Sharon wants to switch from cable to satellite TV. She calls Great Vista Satellite to get a quote. After looking at her cable bill, the salesperson explains that they can provide the same 300 channels Sharon has for $0.20 less per channel. If she switches, her monthly satellite bill will come to $180
Using proportions, it is found that her satellite bill before the switch was of $240.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, she can pay a total of $180 per 300 channels, hence her price per channel will be of:
p = 180/300 = $0.6.
She currently pays $0.2 more, that is, $0.8, hence:
B = 300 x 0.8 = 240.
Her satellite bill before the switch was of $240.

Answer:
1. x = 23
2. y = 14
3. n = 17.5
4. x = 12
5. n = 11
Step-by-step explanation:
Complementary angles are equal to 90°
Vertical angles are congruent, which means they are equal to each other.
Supplementary angles are equal to 180°
1.
2x - 3 + 47 = 90
Step 1: Combine like terms (-3 + 47)
2x - 3 + 47 = 90
2x + 44 = 90
Step 2: Subtract 44 from both sides
2x + 44 - 44 = 90 - 44
2x = 46
Step 3: Divide by 2 on both sides
2x/2 = 46/2
Step 4: Simplify
x = 23
2.
5y + 12 = 82
Step 1: Subtract 12 from both sides
5y + 12 - 12 = 82 - 12
5y = 70
Step 2: Divide by 5 on both sides
5y/5 = 70/5
Step 3: Simplify
y = 14
3.
4n - 5 + 115 = 180
Step 1: Combine like terms (-5 + 115)
4n -5 + 115 = 180
4n + 110 = 180
Step 2: Subtract 110 from both sides
4n + 110 - 110 = 180 - 110
4n = 70
Step 3: Divide by 4 on both sides
4n/n = 70/4
Step 4: Simplify
n = 17.5
4.
Since m∠XYZ = 110°
3x + 2 + 72 = 110
Step 1: Combine like terms (2 + 72)
3x + 2 + 72 = 110
3x + 74 = 110
Step 2: Subtract 74 from both sides
3x + 74 - 74 = 110 - 74
3x = 36
Step 3: Divide by 3 on both sides
3x/3 = 36/3
Step 4: Simplify
x = 12
5.
5n + 35 = 90
Step 1: Subtract 35 from both sides
5n + 35 - 35 = 90 - 35
5n = 55
Step 2: Divide by 5 on both sides
5n/5 = 55/5
Step 3: Simplify
n = 11

Answer:
288
Step-by-step explanation:
Let x represent the smaller number then the larger number would be 120%x
We can use this to set up an equation:
[tex]x+120\%x=528[/tex]
Convert 120% to a fraction (any percentage is just that number over 100):
[tex]x+\frac{120}{100}x=528[/tex]
Simplify the fraction:
[tex]x+\frac{6}{5}x=528[/tex]
Add like terms:
[tex]\frac{5}{5}x+\frac{6}{5}x=528\\\frac{11}{5}x=528[/tex]
Multiply both sides by 5:
[tex]11x=2640[/tex]
Divide both sides by 11
[tex]x=240[/tex]
Therefore...
[tex]120\%*240=\frac{6}{5}(240)=\frac{1440}{5}=288[/tex]
The larger number is 288

Does the point (–1, 1) satisfy the equation y = 4x + 5?
Answer: True
Step-by-step explanation:
Substitute -1 for x and 1 for y in the equation y = 4x + 5
(1) = 4(-1) + 5
1 = -4 + 5
1 = 1
Left side = right side
Therefore, the point (–1, 1) satisfies the equation y = 4x + 5

A map of a highway has a scale of 2 inches = 39 miles. The length of the highway on the map is 9 inches. There are 7 rest stops equally spaced on the
highway, including one at each end. You are making a new map with a scale of 1 inch = 30 miles. How far apart are the rest stops on the new map?
Scale : 2 inches = 39 miles
The length of the highway on the map is 9 inches -> the real length of it = 39 x 9 : 2 = 175.5 (miles)
There are 7 rest stops equally spaced => There are 7-1 = 6 equal distance between the rest stops
So, every rest stop is 175.5 : 6 = 29.25 miles apart from each other.
With a scale of 1 inch = 30 miles, each rest stop will be 29.25 : 30 = 0.975 inches apart from each other on the new map.
