If it is a congruent octagon then the sum of its angles is 1080 bc each angle is 135 degrees
L+m=18, l=18-m
14l+10m=204 using l found above in this we get:
14(18-m)+10m=204
252-14m+10m=204
252-4m=204
-4m=-48
m=12, since l=18-m
l=6
So Elle ordered 6 large and 12 medium pizzas.
You first want to make an equation for the problem. Let x be the number of teams needed since the problem doesn’t include it.
30=5x
Divide 5 by both sides to get x on its own side
*What you do to one side you do to the other
30/5=5x/5
6=x
See it is < and not ≤ so we don't include -4
put a circle around -4 but don't shade it in
to get there, move 4 units left from 0
then we see x is less than -4
so shade to the left of the circle
To find the first number, just multiply the three numbers together.
To find the second number, multiply the three numbers together along with another number (this number can be anything).
<u>What They Have in Common:
</u><u />- All numbers will be even, since you are multiplying by 2.
- All numbers will end in a zero, since you are multiplying by 5 and also 2.
