Evaluate a - c when a = 20.9 and c = -12.8
A:33.7
B:8.1
C:-33.7
D:-8.1
The required evaluation of a - c when a = 20.9 and c = 12.8 is 33.7. Option A is correct.
Given that,
To evaluate a - c when a = 20.9 and c = -12.8.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The given expression,
= a - c
a = 20.9 and c = -12.8.
= 20.9 - (-12.8)
= 20.9 + 12.8
= 33.7
Thus, the required evaluation of a - c when a = 20.9 and c = 12.8 is 33.7. Option A is correct.

A. P = - 13
B. all real numbers
C. No solution
D. P= -2
Answer:
p = -2
Step-by-step explanation:
5p - 10 = + 4(1 + 3p)
first get rid of the bracquetes:
5p - 10 = + 4*1 + 4*3p
5p - 10 = + 4 + 12p
subtract left and right of = sign by 5p
5p -5p - 10 = + 4 + 12p -5p
0 - 10 = + 4 + (12p -5p)
subtract left and right of = sign by 4
-10 -4 = 4 -4 + ( 7p )
re arrange
7p + 0 = -14
divide left and right of = sign by 7

Determine whether each function is even, odd, or neither.
f(x) = Vx²9

DONE
f(x) = x
DONE
g(x) = x + x2

Answer:
First one: Even
Second one: Neither
Third One: Odd
Fourth One: Neither
Step-by-step explanation:
The functions are:
a) f(x) = x² + 9 is neither even nor odd.
b) g(x) = |x - 3| is neither even nor odd.
c) f(x) = x is an odd function.
d) g(x) = x + x² is neither even nor odd.
Here, we have,
To determine whether each function is even, odd, or neither, we examine their symmetry properties under reflection about the y-axis (for even functions) and the origin (for odd functions).
Let's analyze each function:
a) f(x) = x² + 9
This function is neither even nor odd because it does not satisfy the properties of symmetry under reflection about the y-axis or the origin.
b) g(x) = |x - 3|
This function is neither even nor odd because it does not satisfy the properties of symmetry under reflection about the y-axis or the origin.
c) f(x) = x
This function is odd because it satisfies the property of symmetry under reflection about the origin. In other words, f(-x) = -f(x) for all x.
d) g(x) = x + x²
This function is neither even nor odd because it does not satisfy the properties of symmetry under reflection about the y-axis or the origin.
In summary:
a) f(x) = x² + 9 is neither even nor odd.
b) g(x) = |x - 3| is neither even nor odd.
c) f(x) = x is an odd function.
d) g(x) = x + x² is neither even nor odd.

One month, Ruby worked 7 hours more than Isaac, and George worked 3 times as many hours as Ruby. Together they worked 150 hours. How many total hours did they work? Send
Answer:
Issac worked 24.4 hrs, Ruby worked 31.4 hrs, and George worked 94.2 hours
Step-by-step explanation:
x= hours worked
Issac= x Ruby= (x+7) George= 3(x+7)
x+(x+7)+3(x+7) = 150 [distribute 3 to (x+7)]
x+(x+7)+(3x+21) = 150 [add from left to right]
5x+28 = 150 [subtract 28 from both sides]
5x = 122 [divide both sides by 5]
x=24.4
Now plug the x value back into Issac, Ruby, and George's equations:
Issac=x=24.4
Ruby=x+7=31.4
George=3(x+7)=94.2
Double check by adding all their work hours together
24.4+31.4+94.2=150!!
An angle measures 44° less than the measure of its complementary angle. What is the measure of each angle?
a+b=90°
a=b+44°
b+44°+b=90°
2b+44°=90°
2b=90°-44°
2b=46°
b=23°
a=23°+44°
a=67°
The measure of each angle is 23° and 67°.
What is Angle?Angle is defined as the figure formed by the meeting of two lines or rays at a common point.
Complementary angles are those angle whose angle measures sum up to 90°.
Given that two angles are complementary and one of the angle's measure is 44° less than the measure of other one.
Let x be the measure of first angle.
Then x - 44 is the measure of the other angle.
x + (x - 44) = 90°
2x - 44 = 90
2x = 90 + 44
2x = 134
x = 134 / 2
x = 67
One of the measure of angle is 67°.
Measure of other angle = x - 44 = 67 - 44 = 23°
Hence the angle measures are 23° and 67°.

the midpoint of AB is M(1,3).if the coordinates of A are(-1,5),what are the coordinates of B
Answer:
(3,1)
Step-by-step explanation:
let B be (x,y)
m(1,3)=midpoint
A(-1,5)=(x1,y1)
B(x,y)=(x2,y2)
(1,3)= x1+x2/2 y1+y2/2
(1,3)= -1+x/2 5+y/2
so,
-1+x/2=1 5+y/2=3
-1+x=2 5+y=6
x=3 y=1
therefore the co ordinates of B(x,y) are (3,1)
The co-ordinate points of B is (3,1)
What is midpoint in a line ?A midpoint in a given line segment divides the line segment in two equal parts.
In the given question
AB is a line segment.
Point A has co-ordinates (-1,5) and midpoint M has co-ordinates (1,3).
Assuming point B has co-ordinates (x,y)
We know midpoint formula is give by
M of x = (x₁ + x₂)/2 and M of y = (y₁ + y₂)/2
∴ 1 = (-1 + x₂)/2
2 = - 1 +x₂
x₂ = 3
And
3 = ( 5 + y₂)/2
6 = 5 + y₂
y₂ = 1
So the co-ordinate points of B(x₂,y₂) = (3,1)

The senior class purchased pizza to sell after school for $320. If they sell pizza by the slice they make $2 per slice. If they sell a
whole pizza it's $10. Each pizza has 8 slices. Let u represent the number of slices sold and let y represent the number of whole
pizzas sold. If the class has 40 pizzas to sell, what is the greatest number of pizzas they can sell if they want to make a profit of
at least $140.
Answer:30
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
Why!
let x = number of slices sold
let y= number of pizzas sold
If you need to make a profit of at least 140 then you have to make what you paid + what you want = $320+$140 = $460
x= (40-y)8 = 320-8y : 40 is the number of pizza they bought &each pizza has 8 slices
2x + 10y ≥ 460
2 (320-8y) + 10≥460
Just solve it
180≥6y
30≥y
Therefore the greatest number of pizzas you can sell is 30 to make at least $140
Peter will rent a vehicle while his truck is being repaired. Company A charges $25 per day, plus a one-time fee of $60 for rental insurance. Company B charges $45 per day, and the insurance fee is included in the daily rate. The equation 25d + 60 = 45d can be used to find d, the number of days that Peter can rent a vehicle for the same cost from either company
Answer: 3 days
Step-by-step explanation:
25d + 60 = 45d
60 = 20d
3 = d
Check work:
25(3) + 60 = A
75 + 60 = A
135 = A

The sum of the angle measures of the polygon is 540°. Write and solve an equation to find the value of x. Problems- 85 degrees 5x degrees 5x degrees 5x+5 degrees 5x-10 degrees PLEASE HELP!
Answer:
The measure of x is 23 degrees
Step-by-step explanation:
Here, given the values of the angles of a polygon and the total of these angles, we want to find the value of the variable x attached to these angles;
Mathematically;
85 + 5x + 5x + 5x + 5 + 5x -10 = 540
85 + 5 -10 + 5x + 5x + 5x + 5x = 540
80 + 20x = 540
20x = 540-80
20x = 460
x = 460/20
x = 23 degrees
The product of two-thirds and a number plus 6 is 12
Answer:
18
Step-by-step explanation:
Product in math terms means to multiply
When the term "a number" is used, you can just put a variable
"Is," tells you what the problem equals
With this information, we can create the equation:
(2/3x) + 6 = 12
Now that we have this equation, we can solve it
(2/3x) +6 = 12 We can subtract 6 from both sides.
-6 -6
2/3x = 12 We can divide the 2/3 from each side.
/2/3 /2/3
x = 18
Hope this helps!
Answer:
1
Step-by-step explanation:
2/3x + 12 = 6
2/3x = -6
x = -6 divided by 2/3
(6 divided 2) divided 3 =1

Answer:
How do you explain a linear equation?
The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line. An example of linear equation is y=mx + b. "Linear equation."
Step-by-step explanation:
In mathematics, a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation, and may be arbitrary expressions, provided they do not contain any of the variables.
Write an equation for the nth term of the arithmetic sequence. Then find a50.
26, 22, 18, 14, ...
First, we need a few things.
The first term = 26
The common difference = 22 - 26 = -4
26 - 4(n - 1) is our equation.
Let's plug 50 into n to find a50
a50 = 26 - 4(50 - 1)
a50 = 26 - 4(49)
a50 = 26 - 196
a50 = -170
¿Cuánto es 80% de 120 000?
Answer:
96,000
Step-by-step explanation:
.8 x 120,000 = 96,000
mueves el decimal sobre el porcentaje que deseas encontrar, luego lo multiplicas por el total. por ejemplo quiere 80% entonces mueves el decimal para que sea .8 o si quierias 55% entonces es .55 y el total es el 120,000 el numero que tienes. (:
Answer:96000
Step-by-step explanation:
120000/x=100/80
(120000/x)*x=(100/80)*x - we multiply both sides of the equation by x
120000=1.25*x - we divide both sides of the equation by (1.25) to get x
120000/1.25=x
96000=x
x=96000
