Answer:
The answer is A. 0.1x + 18.2
Step-by-step explanation:
We have to simplify the expression
We will use distributive Property of Multiplication with respect to Addition and Subtraction
⇒3×(2.7 x +5) -2 ×(4 x -1.6)
=3×2.7 x +3×5-2×4 x-2×(-1.6)
=8.1 x +15 -8 x+3.2
=(8.1 x- 8 x)+15+3.2-----Adding and Subtracting like terms
= 0.1 x +18.2
Option A
<span>b-3/15=-1
We simplify the equation to the form, which is simple to understand
<span>b-3/15=-1
Simplifying:
<span>b-0.2=-1
We move all terms containing b to the left and all other terms to the right.
<span>+1b=-1 + 0.2
We simplify left and right side of the equation.
<span>+1b=-0.8
We divide both sides of the equation by 1 to get b.
<span>b=-0.8
