Answer:
8x +6y -28
Step-by-step explanation:
The outside factor applies to each inside term, so the equivalent expression is ...
-8(-x -3/4y +7/2) = 8x +6y -28
Applying the distributive property once again, we can also write the equivalent expression ...
= 2(4x +3y -14)
__
There are an infinite number of other equivalent expressions. The problem statement is non-specific as to the acceptable form.
Answer:
Step-by-step explanation:
The amount formula in compound interest is:
where:
P = principal amount
r = annual interest
n = number of compounding periods
t = number of years
We already know that:
P = $2000
t = 7 (number of years from 6th to 13th bday)
n = 4 (quarterly in a year)
Then,
Answer:
Unitary cost= $37.34 = $37
Step-by-step explanation:
Giving the following information:
Number of tires= 8
Total cost= $298.75
<u>To calculate the unitary value of each tire, we need to use the following formula:</u>
Unitary cost= total cost / number of tires
Unitary cost= 298.75 / 8
Unitary cost= $37.34 = $37
The answer is x=4 hope it helps
Answer:
26 year old
Step by step explanation:
Five years ago, John's age was half of the age he will be in 8 years.
this means that (x-5) = (x+8)/2
-----
solving for x, we get:
2 * (x-5) = x + 8
which becomes:
2x - 10 = x + 8
which becomes:
x = 18
-----
john is 18 years old now.
5 years ago john was 13
8 years from now john will be 26
13 = 1/2 * 26
