7 = -x + 3
7- 3 = -x
4 = -x
x = -4 <===== 10 is not a solution
Answer:
.12 = 12/100 or 4/25 I'm not sure if I'm correct but I tried, I'll try solving the other ones and update you
.250 = 25/100 which simplified is 5/20
Answer: Equation: E= 20H
Earning's after 15 hours: E= 20(15)
E = 300
Step-by-step explanation:
The equation would be E =20H. E means her total earnings. 20 is how much money she earns per hour. H is how many hours she tutors. If you put it all together, you get E = 20H.
To solve how much she would get for 15 hours, plug in 15 for H so E=20(15). 20 x 15 = 300. Therefore, she will get $300 after teaching for 15 hours.
