Carmen is taking a road trip. After 25 miles, she reaches a stretch of highway where she can drive at a constant speed of 65 miles per hour. Carmen's friend in the passenger seat is trying to figure out the minimum number of hours Carmen will need to drive to reach over 350 total miles for the trip, assuming she keeps a steady pace.
Carmen's friend creates the inequality 65t + 25 > 350, where t is the driving time, in hours.
Answer:
DEW
Step-by-step explanation:
Answer:
Carmen needs more than 5 hours to meet her goal.
Step-by-step explanation:
to make a valid interpretation of Carmen's situation, solve the given inequality for t.
Carmen could reach 350 total miles at 5 hours if she drives at a constant rate of 65 miles per hour. To reach over 350 miles, Carmen will need to drive for more than 5 hours.
So, Carmen needs more than 5 hours to meet her goal.
Anjali’s school is selling tickets to the annual talent show. On the first day of ticket sales the school sold 18 total tickets for $98. Each adult ticket is $14 and each child ticket $3. How many of each type of ticket were sold?
Answer:
adult-5 student-5
Step-by-step explanation: 98 divided by 18= 5. 5 times 14 = 70. 5 times 3= 15. 70+15=98.
Answer:
adult ticket:4
child ticket:14
Step-by-step explanation:
(98-18*3)/(14-3)=4
18-4=14

5x + 16= -3x please hurry
Answer:
x=-2
Step-by-step explanation:
Answer:
x = - 2
Step-by-step explanation:
5x + 16 = - 3x ( add 3x to both sides )
8x + 16 = 0 ( subtract 16 from both sides )
8x = - 16 ( divide both sides by 8 )
x = - 2

MATH HELP PLEASE !!!! Tickets to a local movie were sold at $5.00 for adults and $3.00 for students. If 150 tickets were sold for a total of $610.00, how many adult tickets and student tickets were sold.
Answer:
A = 80 S =70
Step-by-step explanation:
#Adults tickets = A
#Students tickets = S
A + S = 150
5A (means the price is $5 times the number of Adult tickets) equals the total amount for all of the Adult tickets altogether
3S (means the price is $3 times the number of Student tickets) equals the total amount for all of the students tickets altogether
5A + 3S = 610 (Means adding the total of all the student tickets plus adult tickets will equal $610 for all tickets sold)
Using both equations now, you can use substitution or elimination to solve for one of the variables. Then you can use the variable to substitute to solve the remaining one.
A + S = 150
5A + 3S = 610
Substitution:
A = 150 - S (Rearrange the first equation by moving S to the other side)
Substitute into the other equation
5 (150 - S) + 3S = 610
750 - 5S + 3S = 610 Combine like terms : -2S = -140
Solve for S = 70
Substitute into A + S = 150 A + (70) = 150
A = 80

answer pls : y- (-3y)
Answer:
4y
Step-by-step explanation:
When you subtract an already negative number then the two "minus signs" will become one addition sign and it just becomes y + 3y which is 4y
(Just for example: x- (-8x) would turn into x + 8x and the answer would be 9x)

Answer:

Step-by-step explanation:
Tickets to an outdoor concert cost $15 for general admission tickets and $25 for VIP tickets. Ticket sales totaled $4500. Write an equation that models this relationship. Let x = the number of general admission tickets sold Let y = the number of VIP tickets sold
Answer: 15x + 25y = 4500
Step-by-step explanation:
The cost per general admission tickets is $15 and if x is used to represent the number of general admission tickets then 15 has to be multiplied by x and that gives the expression 15x
The same with the VIP tickets, each one cost $25 and y is used to represent the number of VIP tickets sold, so if you want to find out how much a number of VIP tickets cost then you will have to multiply 25 by y and that derives the expression 25y.
A combination of both tickets has to equal $4500 because that is amount they were both sold to get in total.
15x + 25y = 4500
LOOK AT PIC ATTACHED AND HELP NOW
Answer:
a. Line BC and Line GH
b. Line AC and line AJ
c. No, because if they were perpendicular, they would intersect at a 90 degree angle.
Step-by-step explanation:
a. Whenever two lines share identical little triangle marks - such as line BC and line GH in this case - it indicates that those lines are parallel.
b. The little red square at the intersection of line AC and line AJ indicates a 90 degree angle. Whenever two lines intersect at a 90 degree angle, it means they are perpendicular. So, Line AC and line AJ would be perpendicular.
c. The upside down T symbol means "perpendicular," so the question is asking if line BC and line AJ are perpendicular. However, they cannot be since there is no indication on the diagram that they do - no symbols of 90 degree angles - that we can use to prove that they are perpendicular.

15 inches.......3 inches Which measurement is closest to the total surface area of the container in square inches?
Answer:
[tex]Area = 339.29\ in^2[/tex]
Step-by-step explanation:
Given
See attachment
Required
Determine the total surface area
From the attachment:
[tex]r = 3\ in[/tex] --- radius
[tex]h = 15\ in[/tex] --- height
The total surface area:
[tex]Area = 2\pi r(r + h)[/tex]
Substitute values for r and h
[tex]Area = 2\pi * 3(3 + 15)[/tex]
[tex]Area = 2\pi * 3(18)[/tex]
Remove bracket
[tex]Area = 2\pi * 3 * 18[/tex]
[tex]Area = 2\pi * 54[/tex]
[tex]\pi = \frac{22}{7}[/tex]
So, we have:
[tex]Area = 2 * \frac{22}{7} * 54[/tex]
[tex]Area = \frac{2 * 22 * 54}{7}[/tex]
[tex]Area = \frac{2376}{7}[/tex]
[tex]Area = 339.42[/tex]
Hence, the closest is:
[tex]Area = 339.29\ in^2[/tex]

Answer:
5 forks2 spoonsStep-by-step explanation:
The higher-cost item is forks, so we can let x represent the number of those that are purchased. The total number purchased is 7, so the number of spoons purchased is (7-x).
The total cost is the sum of the costs for each of the items:
6x +5(7-x) = 40
x +35 = 40 . . . . . . simplify
x = 5 . . . . . . . . . . . subtract 35; the number of forks
7-x = 2 . . . . . . . . . the number of spoons
Daniel bought 5 forks and 2 spoons.
_____
Additional comment
Since $40 is not divisible by $6, we can guess that the number of forks Daniel bought will be a multiple of 5. That is, Daniel bought 0 or 5 forks. If he bought 0 forks, then he must have bought 40/5 = 8 spoons, so that is not a viable choice. The only number of forks that makes sense in this problem is 5 forks, so 2 spoons--numbers that total 7, as required.
