Answer: n = 0
Step-by-step explanation:
<u>Given expression</u>
(-3/4) (8n + 12) = 3 (n - 3)
<u>Expand parentheses and apply the distributive property</u>
-6n - 9 = 3n - 9
<u>Add 9 on both sides</u>
-6n - 9 + 9 = 3n - 9 + 9
-6n = 3n
<u>Subtract 3n on both sides</u>
-6n - 3n = 3n - 3n
-9n = 0
<u>Divide -9 on both sides</u>
-9n / -9 = 0 / -9
Hope this helps!! :)

The slope of a line parallel is 4 because a parallel line must have the same slope as the original
Answer:
Pipe 1 twice as fast as pipe 2.
(Pipe 1 time * Pipe 2 time) / (Pipe 1 time + Pipe 2 time) = combined time
(x * (x/2)) / (x + x/2) = 10
(x^2/2) / 1.5 x = 10
x^2 / 2 = 15 x
x^2 /2 - 15 x = 0
x = 30 (slow pipe)
x/2 = 15 (fast pipe)
So it would take 30 hours using the slow pipe only.

Answer:
782 in
Step-by-step explanation:
To find the length of fence, we have to find the perimeter first.
Given
Length = l = 25 feet 8 in
Width = w = 8 feet 8 in
Opening = o =3 feet 6 in
So,
we have to convert the lengths into same unit first
So,
l = (25*12)+8 = 308 in
w = ( 8*12) +8 = 104 in
O = (12*3) + 6 = 42 in
Perimeter = 2(l+w)
= 2(308+104)
=2(412)
=824
As the opening does not need fencing
Total fence = P - o
= 824 - 42
=782 in
or
65 feet 2 in ..
Answer:
18x-16
Step-by-step explanation:
expression: (11x-8)+7(x-1)
ok so what you want to do is combine like terms
but first you are going to distribute
(11x-8)+(7x-8) you distribute the 7
they you can subtract 8 from -8 and that will give you -16
you will then add 11x and 7x which will get you 18x
the final expression will be 18x-16
