<u><em>Answer:</em></u>
70
<u><em>Explanation:</em></u>
Assume that the number we are looking for is x
one tenth is interpreted into ![\frac{1}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B10%7D%20%20)
Now, we know that one tenth of the number is 7, this means that:
* x = 7
Solve for x by multiplying both sides of the equation by 10, we get:
* x * 10 = 7 * 10
x = 70
Hope this helps :)
Answer:
80
Step-by-step explanation:
first add the parenthesis (9+7) = 16
then multiply 16 * 5 = 80
Answer:
Step-by-step explanation:
Perimeter is equal to twice the length plus twice the width
Perimeter = 2L + 2W factoring out the 2
Perimeter = 2(L + W) L = (8x + 5 - 3x) W = (4x - 1)
first I would simplify L collecting the terms of x
L = (5x + 5)
plug in to L and W
Perimeter = 2 (( 5x + 5 ) + ( 4x - 1 )) L = (8x + 5 - 3x) W = (4x - 1)
Perimeter = 2 ( 5x + 4x + 5 -1 ) collect like terms
Perimeter = 2 ( 9x +4) 2 times the 9 and 4
Perimeter = 18x + 8 SOLVE for x
Perimeter - 8 = 18x + 8 -8
Perimeter - 8 = 18x
(Perimeter - 8) / 18 = 18x / 18
(Perimeter - 8) / 18 = x
remember the Perimeter equals 88
(88 - 8) / 18 = x units
4.444444444 units = x
This seems like an odd number so let's it
Perimeter = 2 (( 5x + 5 ) + ( 4x - 1 ))
Perimeter = 2 (( 5(4.444) + 5 ) + ( 4(4.444) - 1 )) = 87.9952
close enough with the rounding off error
