Question

simplify: $0.3(4x - 2) - 0.5(x + 6)$
a. $0.7x + 2$
b. $1.2x - 6$
c. $0.7x - 3.6$
d. $1.2x + 1$

Explanation:

Step1: Distribute coefficients

$0.3(4x - 2) = 1.2x - 0.6$; $-0.5(x + 6) = -0.5x - 3$

Step2: Combine like terms

$(1.2x - 0.5x) + (-0.6 - 3) = 0.7x - 3.6$

Answer:

c. 0.7x - 3.6
