The given equation is
Here we have to solve for x.
First we need to get rid of 9, and for that, we add 9 to both sides. That is
(Addition property of equality)
Now we need to get rid of 2, and for that, we divide both sides by 2.That is
(Division property of equality) .
There are three groups. One group for girls. One group for half the boys which is equal to one group of girls and another identical sized group of boys because there are twice as many boys as girls.
48=total
3=number of groups
48/3=16
16 is equal to the number of girls because it is equal to half the number of boys
16*2=32
32+16=48
Number of boys plus number number of girls: 32+16=48
Answer:
I did my best, but it has been a while. I really hope that this helps
Step-by-step explanation:
so you can find the perimeter of a circle
-----The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle, you need to go halfway around the circle and then across a diagonal to get back to where you started, so the perimeter is 1/2 π × d + d.
Since the 100 degree angle is the same as the m + 20 degree angle, you only have to do: 100-20=80
So the answer is 80
Your answer would be: Continuous Graph
