2/5 and 1/2 can go into 10.
So, 2/5*2 = 4/10
and, 1/2*5 = 5/10.
Got it?
Answer:
x = 1, y = 2
Step-by-step explanation:
In the elimination method to solve a system of linear equations, one of the two equations is added/subtracted to the other, in order to eliminate one variable from the equation.
In this problem, we have the following two equations:

To solve the system, first we multiply by 2 both sides of the second equation, and we get:

So now the system is

Now we add the two equations, and we get:

So, we get

Now we can substitute this value of y into the eq.(2), and we get:

All you do is divide 42,786 by 12
42786÷12=$3,565.50 per month
Answer:
n² + 3n +1
Step-by-step explanation:
n(n+1) + 2n + 1
<h3>i) distribute n into the parantheses</h3>
= (n×n) + (n×1) + 2n + 1
= n² + n + 2n + 1
<h3>ii) collect like terms</h3>
= n² + 3n +1
