The cost of four sweats and two pairs of jeans is $140. the cost of two sweats and theee pairs of jeans is $150. define the variable and write a system of equations to represent this situation?

The system would be:

4x + 2y = 140

2x + 3y = 150

Step-by-step explanation:

If we represent the cost of sweats by the letter x and the jeans by the letter y, we can then write an equation for each of the situations using the number of each in each situation.

4x + 2y = 140

2x + 3y = 150

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
