<u>Answer</u>
If Christina's age is = x
Aaron's age is = x + 6
Jeo's age = 3(x + 6 )
So, the sum of their ages can be write as,

Also, they have given that the sum of their ages is 149
Therefore we can write a equation as,

Now let's solve this and find the age of Christina

Aaron's age is

Joe's age is

C= 3b + 2d
Subtract 3b first.
C-3b = 2d
Divide by 2.
C-3b/2 = d
OR
C-3b
-------- = d Your final answer!

Answer:
x= -7
Step by Step Explanation:
We can write them both like functions like this
A= 5x- 4
B= 3x+ 8
The output of A will be three times the output of B
A=3b
We replace with the functions
5x-4= 3
We solve for x
5x= -4= 9x + 24
5x- 9x= 24 + 4
-4x= 28
x= 28 - 4
x= -7
The output that makes the out put of A 3 times the output of B is -7

Answer:
Step-by-step explanation:
Formula
r = amount / time
Givens
amount = 3/10
time = 2/5
Solution
r = 3/10 // 2/5
Invert the denominator (2/5) and multiply rather than divide.
r = 3/10 * 5/2 Cancel 5 into the 10
r = 3/2 * 1/2
answer: r = 3/4 chord / hour
