Answer:
the consecutive numbers are: 23, 25, 27, 29, 31.
Step-by-step explanation:
23+25+27 is 75
29+31 is 60
75-60 is 15
3y-10 is greater to or equal to 47 add 10 to each side. 3y is great than or equal to 37 Now divide 37 by 3 which gives you an answer of 12.33 I hope this helps you!

→ Use Elimination:
-9x + 3y = -6
-9x + 2y = -10
__________ ---
0 + y = 4
y = 4
→ Use substitution:
-9x + 3y = -6
-9x + 3(4) = -6
-9x + 12 = -6
-9x = -6 - 12
-9x = -18
x = -18/-9
x = 2
So the value of x = 2 and y = 4

We can calculate the number of hours she needs to babysit by the rule of three.
1 hour--------------------$11
x---------------------------$331
x=(1 hour x x$331) / $11=30.0909.... hours≈31 hours
She needs to work 31 hours.
