Answer:
y=40x
Step-by-step explanation:
Yea it's good but make sure to check your answers to see if you did anything wrong.
Lets say a balloon = x
4x + 5x + 6x = 120
15x = 120 (divide each side by 15)
15x/15 = 120/15
x = 8
blue balloons = 4x = 4(8) = 32
red balloons = 5x = 5(8) = 40
yellow balloons = 6x = 6(8) = 48
2 miles every 2/5 hour.
how long for 11 miles
Make a ratio
<u>2/5</u> = <u> x
</u>2 11
cross multiply
(2/5)(11)=(2)(x)
4.4 = 2x
divide both sides by 2
2.2 = x
It will take her 2.2 hours (or 2 1/5) to jog 11 miles.
Hope this helps :)
