Im not sure if i am understanding the question correctly...
If you are asking if Jama's mom is correct, then no. she is wrong. this is because
if you take the proportion, (is/of)=(%/100) you get (x/30)=(70/100). You then solve for x which in this case would be 21 students are wearing tennis shoes.
Hope this helps.
Answer:
-3 1/8 as a decimal is -3.125
The factored form is (y^2+9)(y^2-9).
Plug the two terms into the equation by finding the root of both.
√y^4= y^2
√81= 9
From here, you plug the terms into the form (x+y)(x-y)
(y^2+9)(y^2-9)
Hope this helps!
