each puff of air added will make the balloon rise one unit
Step-by-step explanation:
8) u = vw + z
For v,
u = vw + z
u - z = vw
(u - z)/w = v
v = (u - z)/w
9) x = b - cd
For c,
x = b - cd
x - b = -cd
-(x - b)/d = c
c = -(x - b)/d
= (-x + b)/d
OR
x = b - cd
cd = b - x
c = (b - x)/d
10) fg - 9h = 10j
For g,
fg - 9h = 10j
fg = 10j + 9h
g = (10j + 9h)/f
11) 10m - p = -n
For m,
10m - p = -n
10m = -n + p
m = (-n +p)/10
12) r = (2/3)t + v
For t,
r = (2/3)t + v
r = 2t/3 +v
r - v = 2t/3
3(r - v) = 2t
t = 3(r - v)/2
13) (5/9) v + w = z
For v,
5v/9 + w = z
5v/9 = z - w
5v = 9(z - w)
v = 9(z - w)/5
14) (10ac - x)/11 = -3
For a,
(10ac - x)/11 = -3
10ac - x = -3 × 11
10ac - x = -33
10ac = x - 33
a = (x - 33)/10c
15) (df + 10)/6 = g
For f,
(df + 10)/6 = g
df + 10 = 6g
df = 6g - 10
f = (6g - 10)/d
Karla spent $1500 to make the shirt and will lose $150 if she sells only 90 t-shirts.
<h3>What is an
inequality?</h3>
An inequality is an expression that shows the non equal comparison of two or more numbers and variables.
Let t represent the number of t-shirts she needs to sell in order to make a profit. Since:
t > 100 and the price is $15 per shirt, hence:
Money spent = $15 * 100 = $1500
Money lost in sell 90 shirts = (100 - 90) * 15 = $150
Karla spent $1500 to make the shirt and will lose $150 if she sells only 90 t-shirts.

Answer:
Your answer for both is 31 degrees
Step-by-step explanation:
Because they are similar we know their angles are the same. If you know the rule about triangles' interior angles always add up to 180, then you can just easily find this out.
First you do
82+67 = 149
Take that answer and minus it by 180
180-149 = 31
