Solve for x: 4 over x equals 5 over 10 8 9 20 40
Sati [7]

\frac{4}{x} =\frac{5}{10}   [4 over x equals 5 over 10]  

Solve for x, so you need to isolate/get x by itself in the equation.

\frac{4}{x} =\frac{5}{10}       Multiply x on both sides

(x)\frac{4}{x}=\frac{5}{10} (x)

4=\frac{5}{10} x       Multiply the inverse of 5/10, which is 10/5, to get rid of the fraction and get x by itself

(\frac{10}{5} )4=(\frac{10}{5} )\frac{5}{10} x

\frac{40}{5} =x

8 = x

Hi there!

The measure for the angle B is 13.

A complementary angle equals to 90 degrees. You add (2x + 10) and (3x + 15) and equal it to 90. Combine like terms and balance out the problem like a 2 step variable equations.

Hope this helps !
