Question

On Monday, Mr. Roberts drove 42 miles.

Answer 1

Answer:

The expression is equal to

$\frac{1}{2}(42)+5=26\ miles$

Step-by-step explanation:

Let

x ----->the distance, in miles, driven by Mr. Roberts on Tuesday

y ----->the distance, in miles, driven by Mr. Roberts on Monday

we know that

$x=\frac{1}{2}y+5$ -----> equation A

$y=42\ miles$ -----> equation B

solve by substitution

Substitute equation B in equation A and solve for x

$x=\frac{1}{2}(42)+5=26\ miles$
