Choose the equation that is equivalent to this statement. 90 is 70% of x. math item stem image clear check 90⋅0.7=x 90x=0.07 x90=70100 90x=70100

90/x = 70/100

Step-by-step explanation:

Replace "is" by "=".

Replace "of" by "×".

Then you have ...

... 90 = 70% × x

70% can be writtten any of several ways, including 70/100 or 0.70 or 0.7.

If you divide this equation by x, you get ...

... 90/x = 70/100

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
