Use Pythagorean theorem
A^2 + B^2 = C^2
12^2 + B^2 = 15^2
Solves for b
The constant of proportionality is x=y/5 because its the constant that is not changing in he proportion. It represents the total of members made for washing x cars.
This is a ratio problem. If dry ing : water = 5 : 2, what is water when dry ing = 15?
The new ratio is 15 : water. How do we get from the first ratio to the new one? We multiply by 5. Meaning, we also need to multiply the 2 quarts of water by 5, giving us 10 quarts of water.
-2x + 60
15,30
15 fruit, 30 vegetable
First, to multiplying by a from the both sides.
au=k
Secondly, to divide by u from the both sides.
au/u as a fraction, and it equals to k/u as a fraction.
it equals a=k/u.
Answer is A. a=k/u.
