Glen invited 25 people to his birthday party.
Trava [24]

Answer:

20% of the invited people did not attend

Step-by-step explanation:

5 out of 25 people invited didn't attend Glen's party. That means the following:

\frac{5}{25}  people didn't come which simplifies to  \frac{1}{5}

Multiply \frac{1}{5} by the giant one \frac{20}{20} so the denominator is 100 which is the denominator used to find percentages.

You end up with \frac{20}{100}

\frac{20}{100} = 20%

Determine the solution to the following system of equations: 2x+4y=-12 x+2y=-2
jolli1 [7]

Answer:

undefined/no solution

Step-by-step explanation:

you use elimination to solve. So multiply 2x+4y=-12 by 1 and x+2y=-2 by 2. then you subtract 2x+4y=-12 by 2x+4y=-4 and get 0y=-8. Anything divided by 0 is undefined/no solution because you can't divide anything by 0.

(-4x+9) = (8x-3) find the value of x
NeX [460]

Distributive property: a(b+c)=ab+ac

expand form.

do parenthesis first it's got to be remove.

-4x+9=8x-3

subtract by 9 both sides of an equation.

-4x+9-9=8x-3-9

simplify by equation form.

-4x=8x-12

then you subtract by 8x both sides of an equation.

-4x-8x=8x-12-8x

simplify by equation form again.

-12x=-12

therefore, you can also divide by -12 both sides of an equation.

\frac{-12x}{-12}= \frac{-12}{-12}

finally, simplify equation.

\boxed{x=1}

Hope this helps!

Thanks!
