Answer :
Answer:
b
Step-by-step explanation:
given the equation
0.4r - 0.13 - 0.7r = 3r - 5.74 ( simplify left side )
- 0.3 r - 0.13 = 3r - 5.74 ( add 0.3r to both sides )
- 0.13 = 3.3r - 5.74 ( add 5.74 to both sides )
5.61 = 3.3r ( divide both sides by 3.3 )
[tex]\frac{5.61}{3.3}[/tex] = r , then
r = 1.7
