Answer:
1/2
Step-by-step explanation:
54,56,60,65,30,55,55,65,66 and 65
then place them in order from least to greatest
30,54,55,55,56,60,65,65,65 and 66
and to average they seem to grow equally over and under sixty inches.
1/2 or 50%
5 are lower than 60
and 5 are =/> 60
Let M = total amount of money earned
M = 12x+8y
To make more than $190, the equation is:
190<12x+8y
Since Trevor is going to scoop ice cream for 20 hours, the equation is:
190<12x+8(20), which simplifies to 190<12x+160.
Isolate x to find the amount of hours that Trevor needs to tutor.
190-160<12x
30<12x
30/12<x
2.5<x
Trevor must tutor for more than 2.5 hours to make more than $190.
x=11
(7x+14)=(9x-8)
7x-9x=-14-8
-2x=-22
-2x/-2=-22/-2
He should mix 25 liters of the 30% solution, and 35 liters of 60% solution.
