I WILL MARK BRAINLIEST Twelve is added to a number and then the sum is multiplied by 4/5 to give 23.6. What is the number?
Aliun [14]

Answer: 17.5 or 35/2

Step-by-step explanation:

(If you change 4/5 to a decimal, it makes this easier. 4/5 would be 0.8.)

23.6 = (12 + x)*0.8

23.6 = 9.6 + 0.8x

14 = 0.8x

17.5 = x

17.5 as an improper fraction would be 35/2.

How to answer this ?
inessss [21]

Answer:

Each term is separated by an addition or subtraction sign.

Coefficients are numbers in front of a variable (letter).

Constants are numbers with nothing else.

so you get

2  |  2  |  3              |  1

6  |  6  |  0.2, -1, 8  |   1/2

3  |  -3 |   -              |  -
