Bill wants to purchase some gloves and hats. The gloves cost $12 and a hat costs $8. Bill can spend no more than $56. Let g represent the number of gloves purchased and h represent the number of hats purchased. Which inequality represents this situation?
Step-by-step explanation:
Let g represent the number of gloves purchased and h represent the number of hats purchased.
The gloves cost $12 and a hat costs $8
We need to write an inequality that represents this situation.
Cost of gloves = $12g
Cost of hats = $8h
No more than $56 means [tex]\le 56[/tex].
We can write the inequality as follows :
[tex]12g+8h\le 56[/tex]
Hence, this is the required solution.

The required solution to the given inequality is x > 16, as shown in the graph.
What is inequality?In mathematics, an inequality is a statement that two values or expressions are not equal. An inequality uses one of the comparison symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to). For example, "x + 3 < 10" is an inequality that states that the value of x plus 3 is less than 10.
Here,
As mentioned in the question,
To graph, the solution of the inequality (x+8) > 2 (2.0 + 10).
Simplifying the given inequality:
(x+8) > 2 (2.0 + 10)
x+ 8 > 2(12)
x > 24 - 8
x > 16
Thus, the required solution to the given inequality is x > 16.

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $7.50 and each adult ticket sells for $11. The drama club must make no less than $990 from ticket sales to cover the show's costs. Write an inequality that could represent the possible values for the number of student tickets sold, ss, and the number of adult tickets sold, aa, that would satisfy the constraint.
Answer: ss*$7.50 + aa*$11 ≥ $990.
Step-by-step explanation:
We have two variables:
aa = # of adult tickets sold.
ss = # of student tickets sold.
The total profit is:
P = ss*$7.50 + aa*$11
And we want P ≥ $990.
Then we can write the inequality:
ss*$7.50 + aa*$11 ≥ $990.
Now, we have only one equation and two variables, so there are a lot of possible solutions for this system.

What is the x-coordinate of the midpoint of line segment AB with points A(62, 5) and B(-46, -13).
Answer: 5
Step-by-step explanation:
The x-coordinate of the midpoint of the segment is the average of the x-coordinates of the two endpoints.
Therefore, the x-coordinate of the midpoint of AB is the average of the x-coordinate of A and the x-coordinate of B.
We are given that the x-coordinate of A is 62 and of B is -42.
The average of 62 and -42 = (62-42)/2 = 10/2 = 5

Please help and explain how to do it (extra points)
Answer:
It is C
Step-by-step explanation:
So 3.75 is the rate of change, when she goes to get a drink it changes it subtracts the amount which Mia has which is $50. so we could put y=-3.75x+50 as the equation because for the number of drink she buys multiply by how much she cost will be the money she has to spend, so by subtracting by 50 her gift card will give how much money she will have in her gift card
Hope this helps
Answer: y= -3.75x + 50
Each drink costs Mia $3.75. Since spending money causes her to lose money, this value will be negative. Therefore, we will put -3.75x in the beginning of the equation.
Mia has $50 on a gift card. Since this amount is positive (she has a positive amount of money) and remains constant (the amount on the gift card won't change) we will put +50 at the end of the equation.
HELP ASAP I GIVE 60 points total and big brain!!!! Solve the system of equations by substitution. If there is one solution, express it as an ordered pair. If there is no solution, write no solution. If there is an infinite number of solutions, write infinite number of solutions.
x−y=−5x
x−y=1/3
Solution:
Given:
x - y = -5xx - y = 1/3Substitute the value of "x - y" into equation 1.
x - y = -5x1/3 = -5xDivide -5 both sides.
1/3 ÷ -5 = -5x/-51/3 x 1/-5 = xx = 1/-15 = -1/15Substitute the value of x into equation 2.
x - y = 1/3-1/15 - y = 1/3-1/15 - y = 5/15-y = 5/15 + 1/15y = -6/15 = -2/5Putting the solutions in (x,y) form.
⇒ (x,y) ⇒ (-1/15, -2/5)Answer:
(x, y) = (-1/15, -2/5)
Step-by-step explanation:
You want to solve the system of equations by substitution:
x -y = -5xx -y = 1/3SubstitutionWe can use the second equation to substitute for (x-y) in the first equation:
1/3 = -5x
-1/15 = x . . . . . . . . divide by -5
Substituting this value into the second equation, we have ...
-1/15 -y = 1/3
-1/15 -1/3 = y = -6/15 = -2/5
The solution is (x, y) = (-1/15, -2/5).

Matthew's dad hired him to paint 6 wooden patio chairs for $125. It takes him 9 hours to paint all of the chairs. If it takes the same amount of time to paint each chair, what fraction of an hour does it take Matthew to paint one chair? Justify your thinking with a model.
Given:
Matthew's dad hired him to paint 6 wooden patio chairs for $125.
Time taken by him to paint all of the chairs = 9 hours.
It takes the same amount of time to paint each chair.
To find:
The fraction of an hour does it take Matthew to paint one chair
Solution:
Total time = 9 hours
Total number of chairs = 6
Now, time taken by Matthew to paint one chair is
[tex]\dfrac{\text{Total time}}{\text{Total number of chairs}}=\dfrac{9}{6}[/tex]
[tex]\dfrac{\text{Total time}}{\text{Total number of chairs}}=\dfrac{3}{2}[/tex]
Therefore, Mattew takes [tex]\dfrac{3}{2}[/tex] of an hour to paint one chair.
Thinking with a model: On dividing the total time by total number of chairs we get time taken by Mattew (in hours) to paint one chair. So, the result represents the fraction of an hour taken by Matthew to paint one chair.

= In circle V, VW = 8 and m<WVX = 20°. Find the length of arch W X. Express your answer as a fraction times pi.
The length of the arc WX is the number of units on the arc
The length of the arc WX is [tex]\frac{8}{9} \pi[/tex]
How to determine the length of the arc WX?The given parameters are:
Central angle, m<WVX = 20 degrees
Radius, VW = 8
The length (L) of the arc is calculated as:
[tex]L = \frac{\theta}{360} * 2\pi r[/tex]
Substitute known values
[tex]L = \frac{20}{360} * 2\pi *8[/tex]
Evaluate the product
[tex]L = \frac{320}{360} \pi[/tex]
Simplify the fraction
[tex]L =\frac{8}{9} \pi[/tex]
Hence, the length of the arc is [tex]\frac{8}{9} \pi[/tex]

the fee for ride tickets at a carnival is shown in the table at the right.
b. can you determine the fee of 30 ride tickets? explain.
The fee for 30 ride tickets is 24.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Fee for ride tickets at a carnival is shown in the table at the right.
5 tickets=5 fee
10 tickets=9.50 fee
15 tickets=13.50 fee
20 tickets=16 fee
We need to find the fee for 30 tickets.
Let x be the fee for 30 tickets
20/16=30/x
Apply cross multiplication
20x=480
Divide both sides by 20
x=24
Hence, the fee for 30 ride tickets is 24.
