Club B: 28+23x
Which expression can be used to determine how much more money Club A will cost than Club B after x months?
A....... 7−4x7 - 4 x
B...... 7+4x7 + 4 x

Answers
The expression can be used to determine how much more money Club A will cost than Club B after x months is 7 - 4x
A linear 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 y represent the total cost for x months.
Club A charges a $35 joining fee, plus $19 per month. hence:
y = 19x + 35
Club B charges a $28 joining fee, plus $23 per month. hence:
y = 23x + 28
Club A will cost than Club B:
19x + 35 - (23x + 28)
= 7 - 4x
The expression can be used to determine how much more money Club A will cost than Club B after x months is 7 - 4x

David plays baseball 18 times each month for 3 months. He also plays soccer 15 times each month for 3 months. How many more times does he play baseball than soccer each month?
Plzz help asp
Answers
Answer:
3
Step-by-step explanation:
3 months baseball = 18 x 3 = 54
3 months soccer = 15 x 3 = 45
54-45 = 9
9 / 3 = 3
David plays baseball 3 more times than soccer each month.
David plays 3 more times baseball than soccer each month.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
David plays baseball for 3 months, and each month he plays 18 times.
Also, David plays soccer for 3 months, and each month he plays 15 times.
In 3 months, David plays baseball = 18 x 3 = 54
Also, in 3 months, David plays soccer = 15 x 3 = 45
The more number of times David plays baseball than soccer
= 54 - 45
= 9
In 3 months, David plays 9 more times baseball than soccer.
In one month, David plays 9/3 = 3 more times baseball than soccer.
3 more times David plays baseball than soccer each month.

The largest lollipop ever made had a mass of 2158.7kg and was made for a festival in Granna, Sweden on July 27, 2003, If a spherical lollipop with radius 2 cm has a mass of 50 g, what was the radius of this giant lollipop?
Answers
Answer:
Step-by-step explanation:
Assuming the density is the same for both lollipops, we can calculate what volume is required to make the 2158.7kg the same density of the smaller lollipop.
Small Lollipop
r = 2cm
V=4 /3πr^3
V = 33.51 cm^3
Mass is 50 g in 33.51 cm^3, so the density is:
50g/(33.51 cm^3) = 1.492 g/cm^3
We have 2158.7kg in the larger lollipop. That is 2158700 grams.
Find the volume required to contain 2158700 grams with a density of 1.492 g/cm^3. :
(2158700 grams)/(1.492 g/cm^3) = 1446775 cm^3
V=4 /3πr^3
1446775 cm^3 = (4/3)*π*r^3
r = 70.12 cm

Using the following image, solve the problems below given that M is the midpoint of VW.
If you are using a screen-reader, please consult your instructor for assistance.Using your setup, what are the values of x, VM, MW, and VW?
Answers
The midpoint of a line segment divides the line segment into equal halves.
The value of x is 4The value of VM and MW is 15The value of VW is 30Point M is the midpoint of line segment VW.
So, we have:
[tex]VM = MW[/tex]
Substitute known values
[tex]4x - 1= 3x+3[/tex]
Collect like terms
[tex]4x - 3x = 1 + 3[/tex]
Evaluate like terms
[tex]x = 4[/tex]
Hence, the value of x is 4
The expression for VM is:
[tex]VM = 4x - 1[/tex]
So, we have:
[tex]VM = 4(4) - 1[/tex]
[tex]VM = 15[/tex]
Hence, the value of VM and MW is 15
The length of VW is the sum of both lengths.
So, we have:
[tex]VW = 15 + 15[/tex]
[tex]VW = 30[/tex]
Hence, the value of VW is 30

3y = 2x + 3 → (2)
Substitute 3y = 2x + 3 into (1)
4x + 2x + 3 = - 15
6x + 3 = - 15 ( subtract 3 from both sides )
6x = - 18 ( divide both sides by 6 )
x = - 3
Substitute x = - 3 into (2)
3y = 2(- 3) + 3 = - 6 + 3 = - 3 ( divide both sides by 3 )

Using the function concept, it is found that the correct option is:
C. Yes; the graph passes the vertical line test.In a function, one value of the input can be related to only one value of the output. In a graph, it means that for each value of x(horizontal axis), there can only be one respective value of y(vertical axis). If it happens, it means that the graph passes the vertical line test.In this graph, for each value of x, there is only one value of y, hence it passes the vertical line test, and option C is correct.

Marcus has hired 3 people to help him with his lawn business. He pays all the same, and he pays them every day. He paid $360 to his 3 workers today. How much did each worker get. In complete sentence
Answers
Hi!
If they each got the same, then they each got 1/3 of the total $360. Therefore, we can divide 360 by 3. We can do this by dividing 36 by 3, 36/3, and that's 12. Then add the 0! 120.
Your sentence could be: "The amount of money each worker got can be represented by 360/3, which is $120."
Hope this helps! :D
Answer: Since Marcus hired 3 people and paid them $360 altogether, it should be easy to figure this out through dividing. 360/3 or 360 divided by 3 = 120. You can put three into 360 one-hundred and twenty times. So, your answer would be that each worker got $120.
