Answer:
<h2>4gallons per minute</h2>
Step-by-step explanation:
Step one:
the unit rate is the amount of water per unit of time
Given data
4/5 gallon to decimal= 0.8gallon
1/5 minute decimal= 0.2 minute
We are told that 0.8 gallons run in 0.2 minute
then x gallon will run in 1 minute
cross muliply we have
x=0.8/0.2
x=4
this means that in one minutes 4gallons will run in the faucet
The unit rate is 4gallons per minute
D. 7/8
7/8 = 0.875
2/3 = 0.66667
Since 7/8 is the largest value, it is the furthest from zero.
Answer:
x = 1/2
Step-by-step explanation:
-5x -18 = 9x - 25
-9x +18 -9x +18.
-14x = -7
÷ -14. ÷ -14
x = 1/2
The answer simplified is:
a= —2x^2+7x+22
