Answer:

The answer is B. m∠ POS + m∠ POR = 180

step-by-step explanation:

Because if you already know that m∠POQ equals 90 because it is a right angle

Then all you have to do is take 90 from 180 which is 90 then divide 90 by two which is 45

now you have the measurement for the two acute angles 45

which makes m∠POS = 45 and m∠QOR =45

NOW YOU HAVE TO ADD 90 AND 45 AND 45 ALL TOGETHER THEN YOU WILL HAVE 180

Trey has completed 36 deliveries so far this week. He needs to make 80 deliveries for the week. What percentage of deliveries ha

anygoal [31]

We must build the proportion

deliveries made : deliveries due = x : 100

in fact, we must express the fraction of work done as a fraction with denominator 100.

So, we have

$\dfrac{36}{80}=\dfrac{x}{100}\iff x=\dfrac{3600}{80}=45$

Trey has completed 45% of his work so far.

Y = 3x + 15 3x + 3y = 9

Zina [86]

Answer:

$\Large\boxed{x=-3}$ $\Large\boxed{y=6}$

Step-by-step explanation:

Given the system of equations

$1)~y=3x+15$

$2)~3x+3y=9$

Divide 3 on both sides of the 2) equation

$3x+3y=9$

$3x\div3+3y\div3=9\div3$

$x+y=3$

Current system

$1)~y=3x+15$

$2)~x+y=3$

Substitute 1) equation into the 2) equation

$x+(3x+15)=3$

Combine like terms

$x+3x+15=3$

$4x+15=3$

Subtract 15 on both sides

$4x+15-15=3-15$

$4x=-12$

Divide 4 on both sides

$4x\div4=-12\div4$

$\Large\boxed{x=-3}$

Substitute the x value into one of the equations to find the y value

$y=3x+15$

$y=3(-3)+15$

$y=-9+15$

$\Large\boxed{y=6}$

Hope this helps!! :)
