Answer:
45.367 cm
Step-by-step explanation:
Approximating to a more number of decimal places gives a better estimation of the exact value.
For 45.367 cm, we approximated to three decimal places or five significant figures.
For 43.43 cm, the approximation is done to four decimal places.
Therefore the measurement 45.367cm is more precise because it has a relatively smaller error.
First, distribute the 7:
7w + 14 + 0.5w = 5
Combine like terms:
7.5w + 14 = 5
7.5w = -9
Divide both sides by 7.5 to solve for w:
w = -9/7.5 = -1.2
The answer is -1.2
