So the ones that would be true are m<MKQ+m<PKQ=m<PKM and PK is a bisector. These two are the only ones, the first one wouldn't be true, because we don't know if PKQ and QKM are congruent or not so we can't prove if it's a bisector or not. The second one wouldn't be true for the same reason, we aren't given any information about those two angles. The third isn't true because again, we don't know the angle measures or if they are congruent or not. The fourth is true because the segments of an angle add up to the whole angle. The next one is true because we are given the information that <PKM is a right angle and therefore 90° and a straight angle, which <JKM is said to be is 180°. the last one is not true because we don't know the measures of either of the angles and are given nothing about any congruent angles.

<h3>Answer: B) 6</h3>

===============================================

Explanation:

Add the equations by adding the terms straight down.

The x terms add to x+x = 2x.

The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away

The constants add to 5+7 = 12

The z terms add to -z+z = 0z = 0 and those go away as well

After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.

Pre-orders for the yearbook cost $38 each and full price cost $45 each. If 24 students in Mr. Hillman's class purchased yearbook

aleksandr82 [10.1K]

15 students preordered the year book and 9 students paid full price.

<u>Solution: </u>

Given that

Cost of pre-ordered year book = $\$38$ each

Cost of full price of year book = $\$45$ each

Number of students in Mr. Hillman's class purchased yearbooks = 24

Total price spent by 24 students to purchase year book = $\$975$

Need to determine number of students pre-ordered and number of students paid full price.

Let assume number of student pre-ordered year book = x

As out of 24, x students pre-ordered the yearbook , so remaining are the ones who paid full price

So number of students paid full price = $24-x$

Money spent by students who pre-ordered the book = number of student pre-ordered year book multiplied by Cost of 1 pre-ordered year book = $x\times38 = 38x$

Money spent by students who paid full price = number of students paid full price x Cost of 1 full price year book = $(24-x)\times 45 = 1080-45x$

Total price spent by 24 students to purchase year book = Money spent by students who pre-ordered the book + Money spent by students who paid full price

$\Rightarrow 975=38 x+1080-45 x$

On solving above expression for x, we get

$\begin{array}{l}{\Rightarrow 975-1080=38 x-45 x} \\\\ {\Rightarrow-105=-7 x} \\\\ {\Rightarrow \frac{-105}{-7}=x} \\\\ {\Rightarrow x=15}\end{array}$
