She worked 2 and 1/2 hours yesterday, and today she did 4 and 1/4 hours.
first off, let's check how many hours she worked total, and divide 54 by it.
so, first off, let's convert the mixed fractions to "improper" and add them up.

Answer:
Step-by-step explanation:
1. 2x + y
2. 48 + 60 = 108
3. 840 - 210 = 630
Answer:
331.25
Step-by-step explanation:
First you want to find how much each class cost. So first you want to divide $198.75 by 15 and you will get 13.25. Once you do that you will multiply 13.25 by 25 to get 331.25. Your welcome.
<span>y = x^2 +2x - 35</span>
x-intercept y=0
0 = <span>x^2 +2x - 35
</span>0 = <span>x^2 -5x + 7x - 35 //factoring with leading coefficient
</span>0 = x(x-5) + 7(x-5)
0 = (x+7)(x-5)
x=-7 or x=5
answer: C. -7 and 5
