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:
x = 1
y = -3
Step-by-step explanation:
if y = x - 4
then reorganise the first equation
4 (x - 4) = 9x -21
4x - 16 = 9x - 21
5 = 5x
x = 1
the final temperature was -2 F, and that reflects a drop of 13 units, so
-2------0------------------------------------------------------+11.
Answer:
Length: 139 feet
Width: 104 feet
Step-by-step explanation:
The formula for the perimeter of a rectangle can be given by
. We are given the perimeter of the pool along with the width.


From here, all we have to do is plug back into the original formula:

Which can be further simplified as:


From here, all we have to do is add 70 to both sides of the equation and divide by four:


To make sure that this answer is accurate, we can find that the width of the rectangle should then be 104 (given by 139 - 35). All we have to do is plug back into the original equation:




And the substitution works, so the length of the rectangle would be 139 feet and the width would be 104 feet.
