11. Jimmy bought some used video games and used movies at the Movie Barn. He bought a total of 15 items and spent $106 in all, not including tax. Each used video game cost $10 and each used movie
cost $6. How many of each item did he buy?
Answer:
Used Video game = x = 11
Used movie = y = 4
Step-by-step explanation:
Let
Used Video game = x
Used movie = y
x + y = 15 (1)
10x + 6y = 106 (2)
From 1
x = 15 - y
Substitute x = 15 - y into (2)
10x + 6y = 106
10(15 - y) + 6y = 106
150 - 10y + 6y = 106
-10y + 6y = 106 - 150
- 4y = -44
Divide both sides by -4
y = -44/-4
= 11
y = 11
Substitute y = 11 into (1)
x + y = 15
x + 11 = 15
x = 15 - 11
= 4
x = 4
Used Video game = x = 11
Used movie = y = 4

Answer:
x=70
Step-by-step explanation:
38+x+x+2=180
40+2x=180
2x=140
x=70
Answer:
70
Step-by-step explanation:
x +x +2 + 38 = 180 {Angle sum property of triangle}
2x + 40 = 180
2x = 180 - 40
2x = 140
x = 140/2
x = 70

Step-by-step explanation:
A community center rents their hall for special events. They charge a fixed fee of $200 plus an hourly fee of $22.50. Lin has $300 to spend on renting the hall for a fundraiser.
Using only the money she has, can Lin pay for a 6 hour event? Explain or show your reasoning.
Using only the money she has, can Lin pay for a 3 hour event? Explain or show your reasoning.
If LaTeX: hh represents the number of hours, what does LaTeX: 22.50h+20022.50 h + 200 represent?
Write and solve an equation to determine the number of hours Lin can rent the community center.
Write and solve an inequality that represents this situation. Explain what the solution to the inequality means in this situation.
Lin can only rent the hall for 4 hours with $300.
Linear equationLinear equation is in the form:
y = mx + b
where y,x are variables, m is the rate of change and b is the initial value of y.
Let c represent the cost of renting the hall for h hours.
From the question, we get:
c = 22.5h + 200
If Lin has $330, hence:
300 = 22.5h + 200
h = 4.4 hours
Therefore Lin can only rent the hall for 4 hours with $300.

Item 20 You pay $4.35 for 0.75 pound of American cheese. You buy 2.5 pounds of Swiss cheese for $7.98 per pound. a. How much less does American cheese cost per pound than Swiss cheese? $ less per pound b. How much more do you spend on Swiss cheese than on American cheese? $
Answer:
a. $2.18
b. $15.60
Step-by-step explanation:
a. Price per pound of American cheese = $4.35 / 0.75 = $5.8
Price per pound of Swiss cheese = $7.98
Difference in price per pound = $7.98 - $5.8 = $2.18
b. Total amount spent on swiss cheese = $7.98 x 2.5 = $19.95
Amount spent more on Swiss cheese than on American cheese = $19,95 - $4.35 = $15.60

Answer:
178.7 ft.
Step-by-step explanation:
The kite is (x + 5) ft above the ground. So we need to find x first.
Use the trigonometric identity Sine.
[tex]Sin\ \theta=\frac{perpendicular}{hypotenuse}\\\\sin44=\frac{x}{250} \\\\x=250*sin44\\x=250*0.69\\x=173.66\ ft\\[/tex]
Rounding your answer to the nearest tenth would be 173.7 ft.
Now the kite is above the ground x + 5 which means
173.7 + 5 = 178.7 ft.
