Question

Solve the Proportion for x: 2/3 = x/30

Answer 1

Cross multiply the terms.

Answer 2

or multiply 30 to each side

Answer 3

\[\huge \frac{ 2 }{ 3 } = \frac{ x }{ 30 } ---> 3x = 60\]
now just divide 3 to both sides to get x.

Answer 10

still need help with it or you're okay

Answer 11

\[\huge \frac{ x+1 }{ x^2 + 2x + 1 } + \frac{ 1 }{ x+1 }\]
Simplify the first fraction:
\[\huge \frac{ \cancel{x+1}(1) }{ \cancel{(x+1)}(x+1) } + \frac{ 1 }{ (x+1) }\]
\[\huge \frac{ 1 }{ x+1 } +\frac{ 1 }{ x+1 }\]
\[\huge \frac{ 2 }{ x+1 }\]

Answer 12

thanks guys. im all set. thank you for your help:)
