One fifth is the same as
and 15 is the same as
So just times across,
×
Resulting in(1 x 15= 15, and 5 x 1= 5),
If you need/want to reduce it, divide both numbers by 5. Leaving you with the simplified answer of
or 3. Either answer works. :)

3a- 2b + 8b - 2 + 6a + 3c
3a + 6a -2b +8b + 3c - 2
9a + 6b + 3c - 2
Answer:
a. 
Step-by-step explanation:
The given equation is;
To solve by the x-intercept method we need to graph the corresponding function using a graphing calculator or software.
The corresponding function is
The solution to is where the graph touches the x-axis.
We can see from the graph that; the x-intercepts are;
(-1,0),(3,0) and (6,0).
Therefore the real solutions are:
The mean can be found by adding the two numbers and dividing by 2
let the second number be y
(x + y)/2 = 1/2x + 1
solve for y
multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2
ANSWER: the second number is 2
First we need to calculate how many years her brother has when she is 18. As text says he is:
18/3 = 6 years old
Now when she gains another 18 years (36-18=18) he will also gain those 18 years
When she is 36 he will have 6+18=24 years old
Answer is 24.
