¿cuáles de estas estrategias eliminan una variable en el sistema de ecuaciones? { 2 x + 3 y = − 5 2 x − 3 y = 10 ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ 2x+3y=−5 2x−3y=10

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!

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

if x = 1, then the answer is 3.5
