Answer:
multiply the first equation by -2, then add them
Step-by-step explanation:
7x+4y=-4 *-2 7x+4y=-4 *-2 = -14x-8y=8
5x+8y=28
-14x-8y=8 x=-4, y=6
-9x=36
x=-4
7(-4)+4y=-4
-28+4y=-4
4y=24
y=6
To convert an improper fraction into a mixed number, you must find how many times the denominator fits into the numerator cleanly.
58/7
=8.385
It fits in 8 times.
8*7=56
58-56=2
There is a remainder of 2.
The Mixed number would be 8 2/7.
Hope this helps!

Answer:
Option G: 27 inches.
Step-by-step explanation:
When we have a trapezoid with bases:
B₁ and B₂, the median of the trapezoid can be calculated as:
M = (B₁ + B₂)/2
In this case, we know that the bases are:
B₁ = 30 in
B₂ = 24 in
Then the median is:
M = (30in + 24in)/2 = 54in/2 = 27in
The correct option is G.
