<h3>Let the number be x</h3>
- Multiply all terms by the same value to eliminate fraction denominators
- Cancel multiplied terms that are in the denominator
<h2>Solved ✔︎</h2>
Answer:
a= 1/2p-b
Step-by-step explanation:
p=2a+b
divide by 2 on both sides
1/2 p = a+b
subtract b from both sides
1/2 p - b = a
flip equation (not needed, just personal preference)
a= 1/2p-b

9. 20 because a bisector divides an angle into two equal angles
Using the elimination method, the value of x in the system of equations is calculated as: 8.
<h3>How to Solve a System of Equations by Elimination?</h3>
To solve a system of equations given using the elimination method, do the following:
Multiply 2x - 5y = 1 by 2 and multiply -3x + 2y = -18 by 5 to get the following:
4x - 10y = 2 --> eqn. 1
-15x + 10y = -90 --> eqn. 2
Add
-11x = -88
Divide both sides by -11
x = 8

14.I can't see the whole graph, so you need to do it yourself. Add up everyone's age and divide by the amount of people on the graph. That will give you the average.
