“Rosa is buying T-shirts and shorts. T-shirts cost $20. She plans to spend no more than $120 and buy at least 4 items. Show and describe all possible combinations of the number of T-shirts and shorts she could buy. List 2 possible combinations.” It also states that i have to write a system of linear inequalities and let t represent the number of shorts.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
