Step-by-step explanation:
Nathan buys coffee and hot chocolate for his co-workers. Each cup of coffee costs $1.75 and each cup of hot chocolate costs $1.00. If he pays a total of $14.50 for 10 cups, how many of each does he buy?
Answer:
6 cups of coffee
4 cups of hot chocolate
Step-by-step explanation:
x=number of cups of coffee
y=number of cups of hot chocolate
1.75x+1y=14.5
x+y=10 y=10-x
substitute for y
1.75x+10-x=14.5
0.75x=4.5
x=6
y=10-6=4

Answer:
C
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Express 432 as a product of powers of its prime factors.
We can see easily this is an even number, so let's first divide by 2.
432=2*216
We can see the remaining 216 is still even so we continue.
432=2*2*108
And continue
432=2*2*2*54
and continue
432=2*2*2*2*27
Now we can see that 27 is a multiple of 3 in fact its 3^3.
So we can conclude that 432=[tex]2^4*3^3[/tex]

Answer:13.8
Step-by-step explanation:
Solve y = f (x) for x. Then find the input when the output is -3.
f(x) = 3x+5
Answer:
f(-3)= -4
Step-by-step explanation:
Given function in the question is,
f(x) = 3x + 5
Here, values of 'x' are the input values of the function.
And the values of the function f(x) by substituting the values of 'x' are the output values.
If the output value of the function 'f' is -3,
-3 = 3x + 5
3x = -3 - 5
x = [tex]-\frac{8}{3}[/tex]
Therefore, for the input value x = [tex]-\frac{8}{3}[/tex], output value of the function will be f(x) = -3.

Seven times the sum of a number and six subtracted from four times the number results in negative twenty
Answer:
-20.67
Step-by-step explanation:
Let the number be represented = x
Seven times the sum of a number and six subtracted from four times the number results in negative twenty
7 ×(x + 6) - 4 x x = -20
7(x + 6) - 4x = -20
7x + 42 - 4x = -20
7x - 4x = -20 - 42
3x = -62
x = -62/3
x = -20.67
The number is -20.67

What is the diagram?
Answer:
c/e = e/d
Step-by-step explanation:
These are similar triangles. When you flip the larger one clockwise to enable you to see which sides are corresponding, then you find that:
c corresponds to e'
a corresponds to b
e corresponds to d
Therefore, c/e in the original position = e'/d in the flipped position.
So c/e = e/d

Pls help this is my last problem and I need to pass this class?!?
Answer:
A = 50°
Step-by-step explanation:
[tex](2x - 10) + (x + 30) + 70 = 180 \\ 2x + x = 180 + 10 - 30 - 70 \\ 3x = 90 \\ x = \frac{90}{3} \\ x = 30[/tex]
Then
[tex]a = 2x - 10 \\ a = 2(30) - 10 \\ a = 60 - 10 \\ a = 50[/tex]
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Triangles.
Since we know that, the Angle sum property of a triangle is equal to 180°.
means that, <A + <B + <C = 180°
so we can write as,
==> 2x-10 + x + 30 +70 = 180°
===>3x +90 = 180
==> 3x = 90
hence, x = 30°
so now, substitute angle x,
So angle A is => 2(30)-10 => 60-10 = 50°
hence Angle A = 50°.

What is angle 3
Answer:
Step-by-step explanation:
4x + 6 + 3x + 21 = 8x + 7
7x + 27 = 8x + 7
-x + 27 = 7
-x = -20
x = 20
m<3= 8(20) + 7
160 + 7 = 167
m<1= 4(20) + 6 = 80 + 6 = 86
m<2= 3(20) + 21 = 60 + 21 = 81
12 (x+1/6) = 8 20 points
Answer:
12x + 2
Step-by-step explanation:
12 is multiplyed by both the x and the (1/6) since it is outside the equation.
so 12 times x = 12x since we dont know what x is
and 12 times (1/6) = (12/6) = 2

I have to find slope-intercept equation
Answer:
y = 4x - 9
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
the y-intercept is when the line crosses the y axis, and in this case we can see it at "-9"
The slope we can do rise over run "r/r" ot "y/x"
r/r = 4/1 = 4
The line is positive since its going up
y = 4x - 9
