Tom is 4 more than twice andrews age. if tom and sara are twins, how old is andrew?

The equation for Toms age is 2A + 4

The equation for Sara's age is 5A - 8

You would need to plug in numbers to find which number would give each problem the same result. The correct answer would be 4.

2(4)+4=12

5(4)-8=12

Good luck!

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

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
