Answer:
w=-1.16u
Step-by-step explanation:
first you want to put the W's on one side and the U's on the other. we can do this by subtracting 4u from the left side and the right side making the equations 8w=-7u+2w.
next we want to subtract 2w from both sides making the equation 6w=-7u then we divide by 6 to get w=-1.16u
Answer: Our required equation would be
Step-by-step explanation:
Since we have given that
y=30, when x = 6.
As there is direct proportion between x and y.
so, it becomes,
So, the equation connecting y and x would be
When we put the value of k, we get that
Hence, our required equation would be y=5x

Answer:
6 h
Step-by-step explanation:
The bottom number in the table is half the top number. The missing value is 6 (hours).

I like to put the variable in the numerator of a proportion. Here, we can write it as ...
t/12 = 45/90
Multiplying by 12 gives ...
t = 12(45/90) = 12(1/2) = 6
It will take Darin 6 hours to mow 12 lawns.
