Write and solve an equation to find the value of x. PLSS HELP
natima [27]

Answer & Step-by-step explanation:

Vertical angles are congruent meaning that these two angles are going to have the same measurement. Since we know this, then we can set up an equation where one angle is equal to the other.

x + 10 = 55

Subtract 10 on both sides of the equation.

x = 45

So, the value of x is 45.

It takes 24 workers to complete the job in 5 days. How many days would 15 workers take to do the same job, assuming all the work
zimovet [89]

I'm guessing 10 days, since you lost a bit more than half of the workers, and it would take longer for the job to get done.

I need the solution
Nataly [62]

The only thing you can do here is to try to simplify, so I'll assume that's what you want to do.

\dfrac{b^2-a^2}{2a^2+ab-3b^2}

The numerator is a difference of squares, so it's easy to factorize:

b^2-a^2=(b-a)(b+a)

In the denominator, we factorize by grouping:

2a^2+ab-3b^2=2a^2-2ab+3ab-3b^2=2a(a-b)+3b(a-b)=(2a+3b)(a-b)

So we have

\dfrac{b^2-a^2}{2a^2+ab-3b^2}=\dfrac{(b-a)(b+a)}{(2a+3b)(a-b)}=-\dfrac{b+a}{2a+3b}
