Answer:
8x + 7 = 3 (x = -0.5)
Step-by-step explanation:
I think this is the equation for what you said
If this is the right equation then x would equal -0.5
(hope this helps)
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
"The sum of 8 times a number (x) and 7 equals 3."
Let, "a number" = x
8x + 7 = 3
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
First, subtract 7 from both sides of the equation:
8x + 7 (-7) = 3 (-7)
8x = 3 - 7
8x = -4
Next, divide 8 from both sides of the equation:
(8x)/8 = (-4)/8
x = -4/8
x = -1/2
-1/2 is your number, or -0.5

Dancing Pools sells swimming pools in 4 sizes. The small pool is
72 feet long and 18 feet wide. The medium pool is 80 feet long and
20 feet wide. The large pool is 88 by 22. If the new superduper
Coffeetable pool is 96 feet long, how wide will it be?
Answer:
I believe the answer would be 24
Step-by-step explanation:
the sequence of the pool length is by 8's
72 + 8= 80
80 + 8= 88
88 + 8= 96
and the same goes to the width and it goes by 2's
18 + 2= 20
20 + 2= 22
22 + 2= 24

Write the equation to find the nth term in the arithmetic sequence. First term:-10 and common difference:2
Step by step
Answer:
2n - 12
Step-by-step explanation:
The nth term of an arithmetic progression is expressed as;
Tn = a+(n-1)d
a is the first term = -10
n is the number of terms
d is the common difference = 2
Substitute
Tn = -10 + (n-1)2
Tn = -10 + 2n-2
Tn = 2n -10-2
Tn = 2n - 12
Hence the nth term of the sequence is 2n - 12

Every day of the week. Jordan eams $4 per hour for delivering newspapers He also earns a weekly bonus of $14 if he arrives on time to work each day Last week Jordan arved on time to work every day and earned a total of $108 for h hours of work Based on this situation, which belongs to p in the form px + q = ?
Answer:
(D) Jordan worked a total of 21 1/2 hours.
Step-by-step explanation:
Solution: m=money made
h=hours worked
m=$4(h)+$10
$96=$4(h)+$10 subtract the 10
$86=$4(h) divide by 4
21.5=h

6x + 15 = 8x + 45
Problem:
What value of x makes this equation true?
A -15
B 15
C 17
D-18
Answer:
the answer is A -15
Step-by-step explanation:
Hope this helps!
Answer:
-15
Step-by-step explanation:
6x+15=8x+45
or,6x-8x=45-15
or,-2x=30
or,x=30/-2
or,x=-15
what percent is 52.8 of 55? also how did u get itttt
Answer:
The answer is 96%.
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 55 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 55, so we can write it down as 100%=55.
4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.
5. Now we have two simple equations:
1) 100%=55
2) x%=52.8
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=55/52.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 52.8 is what percent of 55
100%/x%=55/52.8
(100/x)*x=(55/52.8)*x - we multiply both sides of the equation by x
100=1.0416666666667*x - we divide both sides of the equation by (1.0416666666667) to get x
100/1.0416666666667=x
96=x
x=96
now we have:
52.8 is 96% of 55

what information can you automatically find just by looking at a function in standard form
Answer: The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equation.
6. Name the first step in solving 2x - 5 = 37.
a. Add 5 to each side.
b. Divide each side by 2x.
c. Subtract 5 from each side.
d. Multiply 2x to each side.

is 1 1/2 equal to 1 to 2? why or why not
Answer:
No
Step-by-step explanation:
1 to 2 is 1/2
Answer:
No. See below.
Step-by-step explanation:
I've never heard anyone say this out loud. However, on Brainly, it is always interpreted as 1 1/2 = 1.5. So it is 1 plus 1/2.
1 to 2 is a ratio. For every set of car keys I have 2 house keys.
1 to 2 can be written either as 1/2 or 1:2 depending on how touchy your instructor is.
So no. 1 1/2 is not the same as 1:2
You and your 4 friends plane a surprise party. Each of you contributed the same amount of money "m" for food. a) Wright an algebraic expression for the total amount of money contributed for money? b) Evaluate you expression if each person get $5.25 PLEASE HELP ME OF U KNOW I WILL THANK U IF YOU WRITE THE ANSWER FOR MR THANK YOU
Answer:
a) 5m
b) $26.25
Step-by-step explanation:
You and your 4 friends plane a surprise party. Each of you contributed the same amount of money "m" for food.
a) Write an algebraic expression for the total amount of money contributed for money?
Let the total Amount of money each person contributed be = m
Since each person contributed the same amount , and there are 5 people(you and 4 friends)
The total amount of money contributed = 5 × m
= 5m
b) Evaluate you expression if each person get $5.25
From the answer in question a, we have algebraic expression = 5m
m = $5.25
Total cost = 5 × $5.25
= $26.25
