Question

Evaluate the following expression when a = 5 and b = 1. Then, plot the resulting value on the provided number line.

12 + [2 - (4.22)] = 7 + 8

Answer 1

To evaluate the expression 12 + [2 - (4.22)], subtract 4.22 from 2 to get -2.22, then add -2.22 to 12 to get 9.78. The resulting value can be plotted on the number line.

Step-by-step explanation:

To evaluate the expression 12 + [2 - (4.22)], we need to simplify each part of the expression. First, we subtract 4.22 from 2 to get -2.22. Then, we add -2.22 to 12 to get 9.78. Therefore, the value of the expression is 9.78.

To plot the resulting value on the number line, we would locate the point 9.78 and mark it on the number line.
