Answer:

1) Angle AOC + Angle COB = Angle AOB

Angle AOC = X

Angle COB = Y

putting in equation, we get

X + Y = AOB

2) Angle X + Y = AOB (proved above)

AOB = 90° ( given)

Angle X + Angle y = 90°

Angle X is the complement of Y

svetlana [45]

Answer:

$126.20

Step-by-step explanation:

<u><em>Given:</em></u>

<em>Mike is buying eight tickets for a concert. </em>

<em>A package of five tickets costs $74.45. </em>

<em>Individual tickets cost $17.25 each.</em>

<u><em>To Find:</em></u>

<em>What is the least amount that Mike can pay for eight tickets? Be sure to include a decimal point in your answer.</em>

<u><em>Solve:</em></u>

<em>Since we know that:</em>

<em>A package of five tickets costs $74.45. </em>

<em>Individual tickets cost $17.25 each.</em>

<em>Hence we know that 5 + 3 = 8</em>

<em>Thus,</em>

<em>$74.45 = 5 tickets</em>

<em>Now for the 3 tickets we can do individual tickets which cost $17.25</em>

<em>$17.25 × 3 = 51.75</em>

<em>Then we add both together:</em>

<em>51.75 + 74.45 = $126.20</em>

Karen makes $5 per hour for babysitting and $12 per hour giving music lessons. One week she worked a total of 18 hours and made
swat32
B = hours babysitting
m = hours giving music lessons

so... whatever "b" and "m" are, their sum for that week was 18
thus
b + m = 18

now, money wise, she makes $5 for "b" and that is, she made 5*b or 5b that week
for "m", she makes $12, so for that week she made 12*m or 12m

whatever "b" and "m" are
thus

5b + 12m = 139

now \bf \begin{cases}&#10;b+m=18\to \boxed{m}=18-b\\\\&#10;5b+12m=139\\&#10;----------\\&#10;5b+12\left(  \boxed{18-b}\right)=139&#10;\end{cases}

solve for "b", to see how many hours she spent babysitting
