Your answer would be 210.
Bill tells Matt that he has 3 kids. This means that in this item, we have three unknowns, those are the ages of the three kids. First, the product of the ages is 72.
(x)(y)(z) = 72
Also, for the sum of their ages, we have
x + y + z =?
There are three variables in the equation which means that 3 equations should also be presented to determine the ages of the three children.
4/x = 6/(x+3)
6x = 4(x+3)
6x = 4x + 12
2x = 12
x = 6
P = (4 + 6) +(6+3) + 6
P = 10 + 9 + 6
P = 25
False, they actually decreased some.
Answer:
-7
Step-by-step explanation:
To find the common difference, you subtract a term from the term after it. For example, in the problem, you can subtract 13 from 6:
6 - 13 = -7
To check you can do the same thing with other consecutive numbers in the sequence like:
-1 - 6 = -7
