7/12 of people on the playground were on the jungle gym or playing kickball
Answer:
ASA
Step-by-step explanation:
<span>isolate the variable(x)
</span>(when you move numbers from one side to another you change the sign)
2x=22+73-11-23-67
2x=-6
divide both sides by 2
x=-3
Perimeter: 2w+2l
We know the width and the perimeter, which is 18 and 76, so let's plug it in.
76=2(18)+2l
76=36+2l isolate the variable x!
40=2l
20=l
every length is 20 inches.
Let us assume the unknown number to be = x
Then we can easily write the equation as
2x - 6 = -36
Dividing both sides of the equation by 2 we get
x - 3 = - 18
x = - 18 + 3
x = - 15
So the unknown number that we get is -15.

enough for you to understand. You can always use this procedure for
solving similar question in future without taking any outside help.</span>
