Answer:
Shirts = $7
Shorts $17
Step-by-step explanation:
Let:
T - shirts
S - shorts
We can make two equations out of this problem:
4T + 3S = $79
7T + 8S = $185
Through substitution we can solve for one of the unknowns. We make one equation to solve for an unknown

We use the formula of S and insert it into the other equation:

Thus T-shirts are $7 each.
Now that we know T, we can use it to solve for the other unknown. You can use it on any of the formulas.

We know then that Shorts are $17 each.
The height is 5 becuase if the area is 35 that means the length is 7 so you would divide and get 5
Answer:
34
Step-by-step explanation:
-5y=-45
y=-45/-5
=9
y=9
then
5y-11=5×9-11
=45-11
=34
Answer:
x + x + x + x is the same as 4x
because its "x four times"
5x and x+5 are not the same because x+5 in not "x five times"
5x is 5 multiplied by x.
x + 5 is 5 added to x.
