Answer:
<em><u>10 and ten-elevenths</u></em>
Step-by-step explanation:
x = 2 + _/3
(x-1/x)^3
(2+_/3)^3 - (1÷2+_/3)^3
= (8 + 3) - 1 ÷ (8 + 3)
= 11 - 1/11
= 10 10/11
There is no problem on here
Divide 28 by 3 and count how many are left over.
28 / 3 = 9 1/3
So each boy had 9 toy cars, and because you can't have 1/3 cars, you round 1/3 to 1. So there was 1 left over car.
Answer:
2 hours
Step-by-step explanation:
variable x = hours
fix it fast: 25 + 50x
do it right: 35 + 45x
25 + 50x = 35 + 45x
subtract 45x from both sides
subtract 25 from both sides
(this action cancels out 45x on the right side and 25 on the left side so you can combine like terms)
50x - 45x = 35 - 25
5x = 10
divide by 5 on both sides
x = 2
