Answer:
30
Step-by-step explanation:
Set up the proportion y=kx k equals y over x
y=2x
y=30 if x is 15
1/2 an inch = 4 feet.
There are 18 inches
First find how much feet = 1 inch. Multiply 2 to both sides
1/2(2) = 1
4(2)= 8
Now multiply
18 x 4 = 72
72 is your answer
hope this helps
Total Time = (M x K) / (M + K)
5 = (8 x K) / (8 + K)
40 + 5 K = 8K
40 = 3K
King can do the job in 13.33 Hours
King could mow (1 / 13.33) of the lawn in one hour.
6 3/4 hours = (6*60)+45 = 405 minutes
7/5 = 1,4
405 minutes * 1,4 = 567 minutes
= Jack spent 9 3/4 hours
Plug in 6 for x
2^2 - 7(6) - 6
4 - 42 - 6 = -44
