Question in picture above. Thanks guys!

QS is 76

Step-by-step explanation:

Since R is the midpoint of QS:

1) 2x+16 = 5x-17

2) 2x+16+17 = 5x-17+17

3) 2x-2x+33 = 5x-2x

4) 33 = 3x

5) 11 = x

Since the sum of QR and RS equal QS:

1) (2·11+16)+(5·11-17) = QS

2) 22+16+55-17

3) 76 = QS

what is all that apply?

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
