Nico makes $8 per hour at his after school job. he also earned $20 for mowing his neighbors' lawn last week. which equation can be used to find how many hours nico worked if he earned a total of $140?

The equation which is used to find number of hours is

Rico worked 15 hours after school job last week.

Step-by-step explanation:

Given:

Money earned after school job = $8 per hour

Money Earned in Moving neighbors lawn = $20

Total Money earned = $140

We need to find number of hours Nico worked.

Let number of hours Nico worked be x.

Now Total Money earned is equal to Money Earned in Moving neighbors lawn plus Money earned after school job multiplied by number of hours he worked.

Hence framing the above sentence in equation form we get;

Hence the equation which is used to find number of hours is

Solving the above equation we get;

Hence Rico worked 15 hours after school job last week.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

hope this !
