A = 210 + 20(h - 7) <== ur equation
if she earns 410 tutoring...
410 = 210 + 20(h - 7)
410 = 210 + 20h - 140
410 = 20h + 70
410 - 70 = 20h
340 = 20h
340/20 = h
17 = h <=== she spent 17 hrs tutoring
Answer:
0.3
Step-by-step explanation:
4 divided by 12 is .333333333… and the tenths place is right after the decimal point. ex: 5.67 with 6 being in the tenths place. since 3 can’t be rounded upto add onto the tenths place, it stays as .3.
Answer:
The answer would be y= |x-2| -1.
When graphing the answer B would be a larger quantity but A is the correct answer. Hope this helps :))

Answer:
x = 0
Step-by-step explanation:
You can eliminate parentheses and subtract 50.
5(2x +10) = 50
10x +50 = 50 . . . . use the distributive property
10x = 0 . . . . . . . . . subtract 50 from both sides
x = 0 . . . . . . . . . . . divide by 10

<em>Check</em>
5(2·0 +10) = 50
5(10) = 50 . . . . true
