If y varies directly as x, and y=25 when x=5, find y when x=25

The value of y is 125 when x=25.

Step-by-step explanation:

It is given that y varies directly as x. It means y is proportional to x.

Where k is constant of proportionality.

It is given that y=25 when x=5. Put x=5 and y=25 in the above equation to find the value of k.

Divide both sides by 5.

The value of k is 5.

The relation between x and y is defined by the equation

Put x=25 in the above equation.

Therefore the value of y is 125 when x=25.

47 - 90 = 43

43 - 180 = x

x = 137

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
