Question

.4(.5x+10)=2(.3x-7)

Answer 1

Distribute on both sides.
(0.4)(0.5)x + (0.4)(10) = (2)(0.3)x - (2)(7)

Answer 2

0.2x + 4 = 0.6x - 14

Answer 3

would the answer be 22.5 ?

Answer 4

let's see

Answer 5

2x + 40 = 6x - 140
-4x = -180
x = 45
This is what I get

Answer 6

i would multiply both sides by 10 as a start and go with
\[.4(.5x+10)=2(.3x-7)\]
\[4(.5x+10)=20(.3x-7)\] because decimals are annoying
either way will work

Answer 7

45

Answer 8

yeah it is 45
