Answer:
x = 16.5
Step-by-step explanation:
2x + 3y = 73.50
5x + 2y = 109.50
(2x + 3y = 73.5) -5
(5x + 2y = 109.5) 2
-10x - 15y = -367.5
10x + 4y =219
-11y = -148.5
y = 13.5
2x + 3(13.5) = 73.50
2x + 40.5 = 73.5
2x = 73.5 - 40.5
2x = 33
x = 16.5
Answer:Answer: An adult’s ticket costs $9 while a children’s ticket costs $5.
Step-by-step explanation:
1). 2x + 3y = 33
2). 5x + 2y = 55
3). I’m going to use substitution.
Isolate a variable (x):
2x + 3y = 33
2x = -3y + 33
X = (-3y + 33)/2
X = -3/2y + 33/2
Substitute and solve for y:
5x + 2y = 55
5(-3/2y + 33/2) + 2y = 55
-15/2y + 165/2 + 2y = 55
-11/2y = -55/2
Y = 5 <— children’s ticket.
Solve for x:
2x + 3y = 33
2x + 3(5) = 33
2x + 15 = 33
2x = 18
X = 9 <— adult’s ticket.
Check:
5x + 2y = 55
5(9) + 2(5) = 55
45 + 10 = 55
55 = 55
2x + 3y = 33
2(9) + 3(5) = 33
18 + 15 = 33
33 = 33

Erik read a total of 4 books over 2 months. After belonging to the book club for 17 months, how many books will Erik have read in all? plss hep me thank you!!
Answer: 34 books
Step-by-step explanation:
Since Erik read a total of 4 books over 2 months. This means that every month, he read (4/2) = 2 books.
After belonging to the book club for 17 months, the number of books that he'll have read will be the number of books he read per month multiplied by 17 months. This will be:
= 2 × 17
= 34 books
2. A store sells an assortment of batteries
in bulk packs of 300. Of those batteries.
90 are AAA size. What percent of the
pack are AAA-size batteries?
A 10%
B 30%
C 60
D 90
Answer quick PLZZ no website
Answer:
30%
Step-by-step explanation:
# of bulk packs = 300
# of triple As = 90
% = 90 / 300 * 100%
% = .3 * 100%
% = 30%
Answer:
b. 30%
Explanation:
90 ÷ 300 × 100%
= 9 ÷ 30 × 100%
= 0.3 × 100%
= 30%

how many solutions does equation 4x + 3 - 1 = 2(2x + 2) - 2x have explain your reasoning.
Answer:
Anwser: X=1
4x+3-1=2(2x+2)-2x
4x+2=4x+4-2x
4x+2=2x+4
-2 -2x
2x=2
X=1
Step-by-step explanation:
Answer:
one solution
Step-by-step explanation:
Given
4x + 3 - 1 = 2(2x + 2) - 2x ← distribute parenthesis on right side
4x + 2 = 4x + 4 - 2x
4x + 2 = 2x + 4 ( subtract 2x from both sides )
2x + 2 = 4 ( subtract 2 from both sides )
2x = 2 ( divide both sides by 2 )
x = 1

The local pizza restaurant offers free delivery if you live within a 6-mile radius of the restaurant. The restaurant is located at the origin. Ada’s house is 4 miles west and 5 miles north of the restaurant at point (–4, 5). Does Ada’s house lie on or within the circle representing the area that gets free delivery?
a. No, the distance from the restaurant to Ada’s house is miles, which is greater than the 6-mile maximum radius.
b. Yes, the distance from the restaurant to Ada’s house is exactly 6 miles.
c. No, the distance from the restaurant to Ada’s house is 7 miles, which is greater than the 6-mile maximum radius.
d. Yes, the distance from the restaurant to Ada’s house is miles, which is less than the needed 6-mile radius.
Answer:
A.......No, the distance from the restaurant to Ada’s house is miles, which is greater than the 6-mile maximum radius
Step-by-step explanation:
Using the distance between two points, it is found that the correct option regarding whether Ada’s house lie on or within the circle representing the area that gets free delivery is given by:
a. No, the distance from the restaurant to Ada’s house is [tex]\sqrt{41}[/tex] miles, which is greater than the 6-mile maximum radius.
What is the distance between two points?Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
In this problem, we want to find the distance between the restaurant at the origin (0,0) and Ada's house at point (-4,5), hence:
[tex]d = \sqrt{(5 - 0)^2 + (-4 - 0)^2} = \sqrt{41} > 6[/tex]
Greater than 6 miles, hence option a is correct.

Which system of equations is shown by the graph?
Answer:
y-x=15 and 25+2x=y
Step-by-step explanation:
If f (-8)= 0 and f (x)= x^3-x^2-58x+112, find all the zeros of f(x) write your answer in ascending order
Answer:
The zeros in ascending order are 2, 7, 8.
Step-by-step explanation:
Since f(-8) = 0, it means that (x + 8) is a factor of the function f(x)= x³ - x² - 58x + 112.
I have attached the long division of this to get the remaining factors of the polynomial function.
The remaining factor is;
x² - 9x + 14
Using quadratic formula via a calculator, we have; x = 7 and x = 2
Thus,the zeros of the polynomial function f(x)= x³ - x² - 58x + 112 in ascending order are;
2, 7, 8

Given sin y = -4/5, where π < y < 3π/2, and cos x = 12/13, where 0 < x < π/2. Find the exact value of sin (x - y).
Please show all the exact steps in order I am really lost on how to solve this.
Answer:
Solution given:
sin y = -4/5
p/h=4/5
p=4
h=5
b=√{5²-4²)=3
cos y = b/h=-3/5
again
cos x=12/13
b/h=12/13
b=12
h=13
p=√(13²-12²)=5
sin x=p/h=5/13
now
sin[x-y]=sinxcosy-cosxsiny

6. It took Todd 9 hours to paint 4 rooms.
If he continued painting at that rate,
how many rooms could he paint in
12 hours? Explain your reasoning.
Answer quick PLZZ no website
Answer:
5 rooms
Step-by-step explanation:
4 rooms = 9 hours
9 hours = 540 minutes
1 room = 540 ÷ 4 = 135 minutes
60 x 12 = 720 minutes (12 hours)
720 ÷ 135 = 5.33333
5.3333 estimated to nearest whole number = 5

Gary has (20x + 7) dollars. Gary decides to buy two pairs of jeans. Each pair of jeans costs (2x - 3) dollars.
Complete question :
Gary has (20x + 7) dollars. Gary decides to buy two pairs of jeans. Each pair of jeans costs (2x - 3) dollars. write an expression that represents how much money gary will have left over after the purchase then simplify your expression
Answer:
$(16x - 1)
Step-by-step explanation:
Given that:
Amount Gary has = $(20x + 7)
Price per pair of jeans = $(2x - 3)
Number of pairs = 2
Cost of 2 Jean pairs = 2 * $(2x - 3) = $(4x - 6)
Amount left after purchase :
$(20x - 7) - $(4x - 6)
20x - 7 - 4x + 6
20x - 4x - 7 + 6
$(16x - 1)
