Answer:

If the student worked 21 hours this month, she will earn $246.75.

Step-by-step explanation:

<em>Let </em>x<em> equal hours.</em>

If the student earns $11.75 per hour, we can represent this with the expression:

11.75x

If she worked 21 hours this month, then:

x=21

With that information, we can substitute 21 for x in the initial expression:

11.75(21)

Multiply:

246.75

Therefore, if the student worked 21 hours this month, she will earn $246.75.

-

We can check our work by setting the initial expression equal to our solution:

11.75x=246.75

Divide both sides of the equation by the coefficient of x, which is 11.75:

x=21

Since this quotient matches the number of hours she worked, our solution is correct!

Combine like terms.<br><br> - 2/3p + 1/5 - 1 + 5/6p
DaniilM [7]

Answer:

1/6 p -4/5

Step-by-step explanation:

- 2/3p + 1/5 - 1 + 5/6p

When I combine like terms, I put them next to each other.

- 2/3p + 5/6p+ 1/5 - 1

We need to get a common denominator of 6 for the p terms

-2/3 *2/2 p + 5/6 p

-4/6p + 5/6 p

1/6 p


We need to get a common denominator of 5 for the contant terms

1/5 - 1*5/5

1/5-5/5

-4/5


Substituting these in

2/3p + 5/6p+ 1/5 - 1

1/6 p -4/5
