Solve the equation for y:<br> 3 + 5y/2<br> = X

pychu [463]

Answer :

y = $\frac{2}{5} ( x - 3)$

Step-by-step explanation:

6 + 5y = 2x

or, 5y + 6 - 6 = 2x - 6

or, 5y = 2x - 6

or, 5/5 y = 2 ( x - 3) / 5

or, y = 2/5 ( x - 3)

therefore, y = $\frac{2}{5} ( x - 3 )$

The length of the hypotenuse of a right triangle is 137 units. The length of one leg of the triangle is 105. Gina wrote the foll

OLga [1]

A^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 137^2 - 105^2
b^2 = 18769 - 11025
b^2 = 7744
b = sqrt 7744
b = 88

Gina's step is not correct... the length of the unknown leg is not 7744, it is the sqrt of 7744, which is 88
