Answer:

8 hours

Step-by-step explanation:

Eva earns $16 dollars for every 4 hours of dog walking. We already know that half of 32 is 16, so we know that Eva just needs 16 more dollars to get to $32. If she makes $16 every 4 hours, and needs to make $16 more, she needs to work another 4 hours.

For each expression, write an equivalent expression that uses only addition.
konstantin123 [22]

Equivalent expressions are expressions of equal values

The equivalent expressions are 4x+ (y - 8y) + (2z-5z) +6   and 6x-3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)

<h3>How to determine the equivalent expressions</h3>

The first expression has been solved.

So, we have the following expressions

4x−7y−5z+6 and -3x−8y−4−87z

<u>4x−7y−5z+6</u>

We have:

4x-7y-5z+6

Rewrite as:

4x+ (y - 8y) + (2z-5z) +6

<u>-3x−8y−4−87z</u>

We have:

-3x−8y−4−87z

Rewrite as:

3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)

Hence, the equivalent expressions are 4x+ (y - 8y) + (2z-5z) +6   and 6x-3x-6x + (2y - 10y) + (4 - 8) + (z - 88z)
