If you help me with my last question I will help you with this one
5(2y + 7) = 20
5(2y) + 5(7) = 20
10y + 35 = 20
<u> -35 -35</u>
<u>10y</u> = <u>-15</u>
10 10
y = -1 1/2
Answer:
5 hours
Step-by-step explanation:
You just multiply until you get to 125 and since he is earning 25 an hour multiply 5*25 or 25*5 so he will be having to work 5 hours to be able to pay materials
X + Y = 35 - 1
X + Y = 65 - 2
2x= 100
x= 50
50-y= 65
y= 50-65
y= -15
Answer:
560 students
Step-by-step explanation:
6/10 so what i'd do is 1400 ÷ 10 = 140
now you wanna find out the kids that don't like science which was 4/10
so you do 4 × 140 = 560
