PLEASE HELP! I DONT KNOW THE ANSWER! AHHH I WILLL MARK BRILLIANCE IF ITS RIGHT!
April adds the expressions 9x + 7 and 5x – 3. Evan adds the expressions 14x + 2 and 4x + 3. How much greater is Evan’s sum than April’s sum?

Respuesta :

Answer:

4x + 1

Step-by-step explanation:

If April adds her expressions together correctly, she'll get 14x + 4; Evan will get 18x + 5.

Evan's is the greater sum.  So, to answer this question we subtract April's sum from Evan's:

 18x + 5

-(14x + 4)

--------------

 4x + 1

Evan's sum is 4x + 1 greater than April's sum.

Answer:


Step-by-step explanation:

April:

9x + 7 + 5x - 3

First match the numbers with variables

9x + 5x + 7 - 3

Solve!

14x +4


Evan:

14x + 2 + 4x + 3

Do the same thing!

14x + 4x + 3 + 2 --->

18x + 5


Now you have 14x + 4 from April and 18x + 5 from Evan.

replace x with the same number in both equations and solve:

14(2) + 4 = 32

18(2) + 5 = 41


x is not provided so it is impossible to tell how much Evan has more then April.

However Evan will get a higher number no matter what x is.
