Well by the powers to each of these numbers the only you have to multiply the answer by the next answer. This one took some time but i got 56,700,00 i also calculated the answer to see was it correct. It is. Hope this helps!
Answer:
29
Step-by-step explanation:
So DF = 42, And we know that DF = DE + EF
Therefore (7x+1) + (4x-3) = 42
11x -2 = 42
11x = 44
x = 4
Substitute x = 4 onto DE equation, so 7(4) +1
= 29.

Step-by-step explanation:
Anything divided by 0 is undefined. There is no such number that can be divisible by 0.
Given:
Eighteen 2.5 gallon buckets are needed to fill a cistern with water.
To find:
The constant of variation.
Solution:
If y is directly proportional to x, then


Where, k is constant of variation.
In the given problem, water in cistern (w) is directly proportional to number of buckets (n).

(Capacity of each bucket is 2.5 gallons)
Therefore, the constant of variation is 2.5.
