Answer:
Estimating is used to help predict the answer to a calculation. We use estimation to make calculations more manageable and to give us an idea of the answer. Estimation is used in the construction industry, for example, when buying materials and planning labour.
5+10-2^3
= 7
Step by step:
5+10-2^3
= 15 - 2^3
= 15 - 8
= 7
The fastest speed of the William is 7.5 miles per hour. Then the correct option is D.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
William’s typical running speed is 6 mi/h.
The difference between his fastest speed and his typical speed is 1. 5 mi/h.
The equation f - 1.5 = 6 can be used to represent this problem, where f is William’s fastest speed. Then we have
f - 1.5 = 6
f = 6 + 1.5
f = 7.5 mi/h
The fastest speed of the William is 7.5 miles per hour. Then the correct option is D.
