GIVING BRAINLIEST!!! PRETTY SIMPLE QUESTION!!!
Mei subscribed to a magazine at a rate of $24 for 12 issues. When she placed her order, Mei used a coupon that added 3 free bonus issues to her subscription. How did the coupon impact the cost per issue of Mei’s subscription?
O The coupon lowered the cost per issue by $0.40.
O The coupon lowered the cost per issue by $1.38.
O The coupon raised the cost per issue by $0.13.
O The coupon raised the cost per issue by $0.67.
Answer:
A
Step-by-step explanation:
Originally, Mei pays $24 for 12 issues.
Therefore, the cost per issue is:
[tex]c=\frac{\$24}{12\text{ issue}}=\$2\text{ per issue}[/tex]
With the coupon, Mei pays the same amount of $24 but for 15 issues.
So, the cost per issue now is:
[tex]c=\frac{\$24}{15\text{ issues}}=\$1.60\text{ per issue}[/tex]
Therefore, the coupon lowered the price of the issue by $0.40.
Our answer is A.
Answer: The coupon lowered the cost per issue by $0.40.
Original price of issue: $2
24 ÷ 12 = 2
Mei added 3 more issues, but she still pays $24.
The answer is A.
Hope this helps you!

Find the intercepts of the graph given the following equation 4x – 3y = 12
Answer:
y-intercept: -4 or (0, -4)
x-intercept: 3 or (3, 0)
Step-by-step explanation:
4x - 3y = 12
we can convert this to slope-intercept form (y = mx+b) given that m is the slope and b is the y-intercept
4x - 3y = 12
-3y = -4x + 12
y = 4/3x - 4
So the intercept is -4 or (0, -4).
For the x-intercept, we can make the y value 0 to solve for x.
4x - 3y = 12
4x - 3(0) = 12
4x = 12
x = 3
So the x-intercept is 3 or (3, 0).
Is the relation a function? And why
A)No
B)Yes

Answer:
Slope is 4.
Step-by-step explanation:
To find the slope, you can use ¨y=mx+b¨ where m= slope, and b= y intercept.
Hope this helped!
Answer:

Step-by-step explanation:
4x−2y=5
Rewrite in slope-intercept form.
y=2x-5/2
Using the slope-intercept form, the slope is 2.
m=2

Answer:
No real Solutions
Step-by-step explanation:
Step one: The coefficient on -6x is -6. So b= -6
Step two: Add (b/2)^2 to each side. in our case it is 9
x^2-6x+9= -49
Step three: Factor left side
(x-3)^2 = -49
Step four: take the square root
x-3 = ±√-49
Step five: add 3 to both sides
x = 3 ± √-49
So there is no real solutions
Write an equation of the line in STANDARD FORM with a slope of 3 and passes through the point (6,-2) in standard form using the formula
y-y1 = m (x-x1) please!
The formula has been given already, just substitute the values.
m is the slope = 3
y1 = -2
x1 = 6
y - (-2) = m (x - (6))
y + 2 = 3(x - 6)

Two trains are traveling at constant speeds on different tracks.
Answer:
Train B is traveling faster
Step-by-step explanation:
From the picture, we want to know which train is traveling faster
We can know this by knowing the speed of the trains
Mathematically;
speed = distance/time
Train A
12.5 m in 1 second
speed = 12.5/1 = 12.5 m/s
Train B
100 m in 4 seconds
speed = 100/4 = 25 m/s
So train B is traveling faster
This is because it covered a distance of 100 m in 4 seconds as opposed to train A which covered a distance of 12.5 m
in 1 second

Chen completed the division problem below. 0.9 StartLongDivisionSymbol 192.6 EndLongDivisionSymbol right arrow 9 StartLongDivisionSymbol 192.6 EndLongDivisionSymbol minus 18 = 12. 12 minus 9 = 36. 36 minus 36 = a remainder of 0 and a quotient of 21.4. What is Chen’s error? He included a 4 in the quotient, which does not belong. He multiplied the dividend by 100 instead of 10. He should have multiplied both numbers by 100. He did not subtract correctly in one of the steps.

Write three factors of 24 which have a sum of more than 37 and less than 40
Answer:
24, 12, 2
Step-by-step explanation:
24, 12, and 2 are all factors of 24.
24+12+2=38
37<38<40
the three factors of 24 that have a sum between 37 and 40 are 2, 12, and 24, with a sum of 38. Another combination is 4, 8, and 24, also with a sum of 38.
To find three factors of 24 with a sum between 37 and 40, we can start by listing the factors of 24:
1, 2, 3, 4, 6, 8, 12, 24
Next, we'll try different combinations of these factors to see if any three of them add up to a sum between 37 and 40:
1 + 2 + 24 = 27 (not within the desired range)
1 + 3 + 24 = 28 (not within the desired range)
1 + 4 + 24 = 29 (not within the desired range)
1 + 6 + 24 = 31 (not within the desired range)
1 + 8 + 24 = 33 (not within the desired range)
1 + 12 + 24 = 37 (not within the desired range)
2 + 3 + 24 = 29 (not within the desired range)
2 + 4 + 24 = 30 (not within the desired range)
2 + 6 + 24 = 32 (not within the desired range)
2 + 8 + 24 = 34 (not within the desired range)
2 + 12 + 24 = 38 (within the desired range)
3 + 4 + 24 = 31 (not within the desired range)
3 + 6 + 24 = 33 (not within the desired range)
3 + 8 + 24 = 35 (not within the desired range)
3 + 12 + 24 = 39 (within the desired range)
4 + 6 + 24 = 34 (not within the desired range)
4 + 8 + 24 = 36 (within the desired range)
4 + 12 + 24 = 40 (not within the desired range)
6 + 8 + 24 = 38 (within the desired range)
6 + 12 + 24 = 42 (not within the desired range)
8 + 12 + 24 = 44 (not within the desired range)
Therefore, the three factors of 24 that have a sum between 37 and 40 are 2, 12, and 24, with a sum of 38. Another combination is 4, 8, and 24, also with a sum of 38.
