Question

Equation 7th grade math

Answer 1

Answer is c

Distribute 2 through parenthesis
Collect like terms
Find the Sum

Answer 2

To solve this problem,

⇒ must use PEMDAS and fractional conversions

⇒ I attached an image of what is PEMDAS below

Let's solve:

`2(x+7)-18x+(4)/(5) =2x+14-18x+(4)/(5) =14-16x+(4)/(5)`

Here we convert 14 into a fraction with a denominator of 5 so that we

can add it to 4/5

`14*1-16x+(4)/(5) =14*(5)/(5) -16x+(4)/(5) =*(14*5)/(5) -16x+(4)/(5) \\=(70)/(5) -16x+(4)/(5) =(70)/(5) +(4)/(5) -16x=(70+4)/(5)-16x\\ =(74)/(5) -16x=-16+(74)/(5) \\=-16+(74)/(5)`

Answer: Thus the expression equivalent to the function given is (C)

Hope that helps!
