Ok for 22 you just have to add both of them together and set them to equal 90. ( 4z+ 3z+6=90). then you solve for z by combining like terms giving you 7z+6=90 then subtract 6from both side leaving you with 7z=84. then divide to get z=12. you thin plug 12 into the angles such as 4(12) and 3(12)+6 which give you 48 and 42 degrees and to double check just add your 2 degrees together to form 90.

on problem 20, add both angles together and set to 180 (4h+5+8h-5=180) since the line is like half a circle. then combine like terms (12h=180) divide by 12 and then after dividing 180 by 12 and getting 15 you substitute 15 in for h.

If the original quantity is 14 in the new quantity is 24 estimate the percent change<br>

denis23 [38]

Answer:

$\% \: change = \frac{(24 - 14)}{14} \times 100 \\ = \frac{10 \times 100}{14} \\ = \frac{1000}{14} \\ = 71.43\%$

<h2>Percentage change is 71.43%.</h2>

fgiga [73]

To find n
1. Subtract 8n from both side to get -3n=30
2. Divide both sides by -3 to get n=-10

Gavin and Caleb go to the movie theater and purchase refreshments for their friends. Gavin spends a total of $22.25 on 2 bags of

gavmur [86]

Answer:

Drinks = 6.75

Popcorn= 1

Step-by-step explanation:

Let the popcorn = P

Let the drink = D

2*P + 3*D = 22.25 multiply this equation by 6

12*P + 4D = 39.00

<u>12P + 18D = 133.5</u> Subtract these two equations

- 14D = - 94.50 Divide by -14

-14D/-14 = -94.5/-14 Do the division

D = 6.75

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

12P + 4D = 39 Substitute for D

12P + 4*6.75 = 39 Combine

12P + 27 = 39 Subtract 27 from both sides

12P + 27-27=39-27 Collect like terms

12P = 12 Divide by 12

12P/12 = 12/12

P = 1 Answer

A store sells boxes of juice in equal size package Garth bought 18 boxes Rico Ball 36 boxes in my 45 boxes what is the greatest

monitta

I'm not sure I'm understanding the wording of the question, but if it's this:

Juice boxes come in a package with multiple juice boxes in each package. Three people bought 18, 36, and 45 juice boxes. What is the largest possible number of juice boxes per package?

Then the problem is just an involved way of asking what the greatest common factor of 18, 36, and 45 is, and the answer is 9, the difference between 36 and 45, which are both multiples of 9. Note that 18 is also a multiple of 9. One way to find the greatest common factor of three numbers is to factor all of them and find which prime factors they have in common.
