At the Manchester Ice Cream Parlor, one group of friends ordered 1 small serving of ice cream and 1 large serving of ice cream for $5. Another group of friends ordered 4 small servings of ice cream and 5 large servings of ice cream for $24. How much does the ice cream cost?

The ice cream costs $__ for a small serving and $__ for a large serving.`

Answers

large is $4
small is $1

Answer:

$24

Step-by-step explanation:

5 large servings = 4 + 4 + 4 + 4 + 4 = $20

4 small servings = 1 + 1 + 1 + 1 = $4

20 + 4 = $24

The ice cream costs $1 for a small serving and $4 for a large serving.

The perimeter of a square is 100 feet. What is the length of one of its​ sides? Explain your work.

Answers

Answer:

25

Step-by-step explanation:

to find the perimeter you add up all the sides and since it's a square and squares have all four equal sides

you just divide 100/4=25

4 sides of a square. Each side of a square is equal. You said the perimeter is 100. So if we put it in an equation, lets say S = Side. 4s=100. Now we just divide. s=25

Each side is 25

Solve the system of equations below by elimination. Write your answer as an ordered pair. e.g. (2,3)

Answers

Answer:

(45,35)

Step-by-step explanation:

1 - Stack the equations on top of each other

3x - 4y = -5

4x + 4y = 40

2 - We can eliminate by subtracting the bottom equation from the top equation

 3x - 4y = -5

- 4x - 4y = 40

3 - The y's cancel out, leaving us with...

 3x = -5

- 4x = 40

4 - Continue simplifying

-1x = -45

5 - We can switch the -1x with -x to make things simple

-x = -45

6 - Positize (make it positive) the statement

x = 45

7 - Halfway there! Substitute the x value into one of the equations

(3 * 45) - 4y = -5

8 - Solve

135 - 4y = -5

Minus 135 on both sides

-4y = -140

Divide by -4 on both sides

y = 35

9 - Here is your answer!!

x = 45

y = 35

(45,35)

Jezebel took a train to visit her uncle. The train traveled at a constant speed of 40 miles per hour. Complete the table.​ Then, write an equation to find the total distance d traveled after t hours.

Answers

Answer:

[see below]

Step-by-step explanation:

We can tell that for every hour passed the distance traveled by the train would increase by 40 miles.

We can use the equation d = 40t to determine the values of the table. The 'd' is total distance and 't' is the number of given hours.

Two hours:

d = 40(2)

d = 80

Three Hours:

d = 40(3)

d = 120

Four Hours:

d = 40(4)

d = 160

Hope this helps.

Multiply 40 by that number so basically y=Mx+b

Answers

5 hours if there was supposed to be an x after 20 on the second equation

It will take 5 hours for the cost to be the same for both companies.

What is an equation?

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

Collin needs to repair his malfunctioning air conditioner.

He makes the decision to phone a few technicians to find out how much it would cost to fix the device.

Let x stand for the number of hours and y for the overall expense.

Company A: y = 25x + 20

company B: y = 20x + 45

To find the number of hours it will take for the cost to be the same for both companies, we need to solve the equation:

25x + 20 = 20x + 45

Simplifying the equation, we get:

5x = 25

x = 5

Therefore, x = 5

The formula to find out the volume of a rectangular prism is V = l × b × h where V is the volume , l = length , b = breadth & h = height.

We're provided the figure of trapezium in the second attachment. The formula to fInd out the area of trapezium is A = [tex] \tt{ \frac{1}{2} h(a + b)}[/tex] where a and b are the opposite parallel sides and h be the height of a trapezium.

[tex] \large{ \tt{❃ \: SOLUTION}} : [/tex]

In the first picture , we're provided - Length ( l ) = [tex] \frac{7}{4} [/tex] cm , breadth ( b ) = [tex] \frac{3}{2} [/tex] cm and height ( h ) = [tex] \frac{1}{2} [/tex] cm. Now, plug these known values and them find out the volume of given rectangular prism.

[tex] \large{ {⟶ \: \frac{7}{4} \times \frac{3}{2} \times \frac{1}{2} }}[/tex]

To multiply one fraction by another , multiply the numerators for the numerator and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term if possible.

In the second attachment , we're provided - 6ft and 7 ft are the opposite parallel sides and 3 ft is the height of the given trapezium.
