Question

Evaluate the expression when c = -3/10 and x = -7/8c + 1/5xWrite your answer in simplest form.

Answer 1

`(-19)/(40)`

Step-by-step explanation:

if c = -3/10 and x = -7/8

by replacing them in the equation c + 1/5 * x, we get:

`(-3)/(10)+(1)/(5)*(-7)/(8)\text{ = }(-3)/(10)-(7)/(40)=\frac{-3*4}{10\text{ * 4}}-(7)/(40)=\text{ }(-12-7)/(40)\text{ = }(-19)/(40)`
