Good answer, beababy !!!!
18/25 = x / 100 cross-multiply
25x = 1800 divide both sides by 25
x = 72
So
18 / 25 = 72 / 100 = .72 = 72%
Nope, MG.......still with us.......1 + 1 = ??? is still around, too......
16 = 4 x 4 = 42
(7 + 9/18) - ( 3 + 2/18) =
4 + 7/18
If we have :
y = (4/9)x , then y varies directly with x....as x grows larger, y grows larger.......and as x gets smaller, y gets smaller
The variation constant is (4/9)

I think you mean "inverse" tangent
Hit the 2nd key on the calculator
Find the "atan" key
Enter your value
Hit " = "
positive x negative = negative
Do you see the answer(s) ???
2 = p^2 take the positive/negative square root of both sides
(plus/minus)sqrt(2) = p
Then 8p = (plus/minus)8*sqrt(2)
