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.`
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.

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

Collin needs to fix his broken air conditioner unit. He decides to call some mechanics to see what it might cost to get the unit repaired. Let’s x represent the number of hours and let y represent the total cost.
Company A: y = 25x + 20
company B: y = 20 + 45
it will take ____________ hours for the cost to be the same for both companies
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

Answer:
6x+9x and 3(2x + 3x)
Step-by-step explanation:
Answer:
The Bottom Right option would be correct, 6x + 9x and 3 (2x + 3x)
Step-by-step explanation:
If put 3 (2x + 3x) in standard form, it would result in;
3 * 2x = 6x
3 * 3x = 9x
Therefore
3 (2x + 3x) = 6x + 9x

2 3/4 pounds of chicken. How many more pounds of chicken does Valentino need?
Answer:
Valentino needs 1 [tex]\frac{3}{4}[/tex] more pounds of chicken for the recipe.
Step-by-step explanation:
You just need to know how to subtract fractions.
Valentino needs 4 and 1/2 pounds of chicken for a recipe, and he already has 2 and 3/4. We want to know how many more pounds of chicken we need, so you subtract.
4 1/2 - 2 3/4 = 4 2/4 - 2 3/4
= 1 3/4
Valentino needs 1 and 3/4 pounds of chicken still.

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.
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

Answer:
1)
V = l * w * h
7/4 * 3/2 * 1/2 = 21/16 cm^3
2)
A = a+b ÷ 2 * h
6 + 4 = 10 ÷ 2 = 5
5 * 3 = 15 ft^2
The perimeter of a square is 100 feet. What is the length of one of its sides? Explain your work.
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
