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.
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.
