SOMEBODY PLEASE HELP ME IN GEOMETRY

x=1

Step-by-step explanation:

RS + ST = RT

7x-1 + 2x-1 = 7

Combine like terms

9x-2 = 7

Add 2 to each side

9x-2+2 = 7+2

9x= 9

Divide by 9

9x/9 = 9/9

x = 1

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
