Answer:

\boxed{\bold{x=-\frac{7}{3}}}

Step-by-step explanation:

Expand: \bold{5\left(2x\right): \ 10x}

Expand: \bold{7\left(x-1\right): \ 7x-7}

\bold{10x=7x-7}

Subtract 7x From Both Sides

\bold{10x-7x=7x-7-7x}

Simplify

\bold{3x=-7}

Divide Both Sides By 3

\bold{\frac{3x}{3}=\frac{-7}{3}}

Simplify

\bold{x=-\frac{7}{3}}

katen-ka-za [31]

Answer:

Hello! I hope I am correct!

Step-by-step explanation:

295 feet will equal to 89.916 meters.

(295 feet is equivalent to 89.916 meters!)

Will equal 89.916 meters.

Therefore, 295 feet = 89.916 meter

Hope this helps!
