Question

Which expression is equivalent to 10f−5−5f+2? 15f−3 5f−7 15f−7 −3+5f

Answer 1

Answer:

$10f - 5-5f +2 =5f -3= -3+5f$

last option

Answer 2

Answer:

C

Step-by-step explanation:

If we solve 10f-5f+8+69+4, We get 5f+81 (put in comments if you want a step by step explanation on how i solved this).  

Let's try to solve each of the options.  

A) 15f + 14g + 4  

It would not be option A because there isn't a variable such as g in the expression.  

B) 15f + 8 + 10g

 

C) 5f + 69 + 12

5f+ 81  

This one is correct because the expression also equals 5f+81  

D) 5f + 149 +4​

5f+ 153  

D would be wrong as well

Hope this helps! <3
