Step-by-step explanation:
(5b - 2c)*(2a - 3c) = 5b*2a - 3c*5b - 2a*2c + 6c^2
1/5(x-y) = 1
x+y = 9
x-y = 5 (x5)
x+y = 9
First you want to create both equations so at least one of the variables (x or y) are the same in both equations, so that is why I multiplied the top one by 5, you multiply the whole equation (both sides)
2x = 14
x = 7
Then you either Plus or minus one from the other, I plused the top one onto the bottom one, then solved for x
7 + y = 9
y = 2
Then put x back into one of the first two equations to get Y

<u>Answer:</u>
The maximum number of turkey sandwiches Ben could have sold is 6.
<u>Step-by-step explanation:</u>
We are given that turkey sandwiches cost $2.50 and veggie wraps cost $3.50 at a snack stand.
Given the information, we are to find the maximum value of turkey sandwiches Ben could have sold.
Number of veggie wraps sold (y) = 4
2.50x + 3.50(4) < 30
2.50x + 14 < 30
<u> - 14 -14
</u>
2.50x < 16
The maximum number of turkey sandwiches Ben could have sold is 6.
