Answer:
120/6=20
Step-by-step explanation:
If the drawing of your octagon (or whatever) has been separated into triangles, and one triangle's area<span> is labeled, then you do not need to know the apothem. Just take the </span>area<span> of that one triangle, and multiply by the number of sides in the original </span>polygon<span>.</span>
In this question, you're solving for x.
Solve for x:
2(x - 8) + 4x = 6(x - 2) - 4
Distribute the 2 to the variables inside the parenthesis.
2x - 16 + 4x = 6(x - 2) - 4
Distribute the 6 to the variables inside the parenthesis.
2x - 16 + 4x = 6x - 12 - 4
6x - 16 = 6x - 12 - 4
6x - 16 = 6x - 16
Subtract 6x from both sides
-16 = -16
Add 16 to both sides
0 = 0

Answer:
B=0.10x+2
Step-by-step
sponsor b is paying .10 x 52 pins + $2. = 5.20 + 2 = 7.20
it isn’t the 2 times 52
it is not subtracting the money
and we have to consider the 52 pins as X
Answer: When they work 10 hours each, they both make $300.
kelli y = 20x + 100
karl y = 25x + 50
substitution:
y = 20x + 100
25x + 50 = 20x + 100
-20x -50 -20x -50
--------------------------------
5x = <span>50
</span>5 5
x = 10
(Then plug into any equation)
y = 25x + 50
y = 25(10) + 50
y = 300
When they work 10 hours each, they both make $300.
