Answer: x=40

Step-by-step explanation x-0.3x=28

Add similar elements x-0.3x=0.7x

0.7x=28

Multiply both sides by 10

0.7x · 10= 28  · 10

Refine

7x=280

Divide both sides by 7

Simplify

x = 40

I think the Honda and Dodge have the same ratio. If you do the math, the ratio will come out to (12,1) or 12 for both types of cars.

-6x-4+5x=4<br> What is "x". Please show your work.
4vir4ik [10]

Answer:

first thing to do is combine like terms

now you would have -x-4=4

this is because you added -6x+5x

now you would add 4 to each side

now you would have-x=8

then you would divide the negative because x has to be positive

now you would have x= -8

that is your answer. if you any questions just ask :D
