Answer:
8 shirts, $60
Step-by-step explanation:
Company A: 20+5x=y
Company B: 7.50x=y
Since y represents the amount of money and x represents the number of shirts, you set them equal to each other and solve for x to find the number of shirts where they will have the same amount of money.
20+5x=7.50x
20=2.50x
x=8 shirts
Now that we know they will have the same amount of money at 8 shirts, you just plug in 8 for x on one of the starting equations. You can plug 8 in to both to double check that it gives the same value for both.
20+5(8)= 60
7.50(8)= 60
We have verified that with 8 shirts, they will both be making 60 dollars.

Answer:
c. x>1/2
Step-by-step explanation:
Distribute the -2 to eliminate parentheses:
6x -2x -2 > 0
4x -2 > 0 . . . . . . combine terms
Now, you can divide by 4:
x -2/4 > 0
and add 1/2
x > 1/2 . . . . . matches choice C
Answer:
11v^2 - 8v + 1
Step-by-step explanation:
(4v^2 - 5v - 1) + (7v^2 - 3v + 2)
open brackets
4v^2 - 5v - 1 + 7v^2 - 3v + 2
place like terms together (remember signs remain same )
4v^2 + 7v^2 - 5v - 3v + 2 - 1
add or subtract like terms
11v^2 - 8v + 1
