<ABC = 85
Step-by-step explanation:
3x + 25 + 5x - 5 = 180
8x + 20 = 180
- 20 - 20
8x = 160
/ 8 / 8
x = 20
3x + 25
3 (20) + 25
60 + 25
85

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.

A music club membership costs $15 to start and $8 per cd. Write an equation.
Answers
Answer:
y = 8x + 15
Step-by-step explanation:
Let x represent the number of cds, and let y represent the total cost.
Since each cd is $8, we can represent the extra cost from cds with the term 8x.
And, since the membership costs $15, this cost can be represented in the equation by +15.
Put these together:
y = 8x + 15 will be the equation representing this

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?
Answers
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

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? $
Answers
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

Answers
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.
