Solve for w. 0.7(w+1.2)=2.1 (1 point)

Question

-0.9
1.8
4.2
0.9

Answer 1

To solve for w, we can start by simplifying the equation:

0.7(w+1.2) = 2.1

Distribute 0.7 to the terms inside the parentheses:

0.7w + 0.7(1.2) = 2.1

0.7w + 0.84 = 2.1

Next, subtract 0.84 from both sides to isolate the term with w:

0.7w = 2.1 - 0.84

0.7w = 1.26

Finally, divide both sides by 0.7 to solve for w:

w = 1.26 / 0.7

w ≈ 1.8

So the value of w is approximately 1.8. Therefore, the correct answer is 1.8.
