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
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.

Answer:
2.4=x
Step-by-step explanation:
So, to solve this, we need to divide a length of one side of one shape by the length of the same side of the opposie shape.
We have several lengths we can use:
4.8 and 4 = 4.8/4= 1.2
3.6 and 3 = 3.6/3 = 1.2
6 and 5 = 6/5 = 1.2
So as we can see, the change or ratio between the two shapes is 1.2
Now lets multiply the 2 on the first shape by the 1.2 ratio to find the x value on the other shape:
2*1.2=2.4
So x=2.4
Hope this helps!
===========================================================
Explanation:
There's a lot to get lost in here, so I can see why it's intimidating. For me, it helps to focus on a few things at a time and try to build from there.
We only need 4 pieces of info to help find x. I'll circle what we need in the diagram below (see attached image). Note the color coding to see how the terms match up.
Since we have similar figures, the corresponding sides form proportional ratios. This means DE/ST is the exact same as EA/TP. I've indicated this in the diagram as well.
So that's why 2/x = 4/(4.8)
-----------------------
Let's solve for x in the equation below.
2/x = 4/(4.8)
2*4.8 = x*4 ... cross multiply
9.6 = 4x
4x = 9.6
x = (9.6)/4 .... divide both sides by 4
x = 2.4
Therefore, segment ST is 2.4 units long.
-------------------------
Side note: The decimal 2.4 converts to the improper fraction 12/5, which is equivalent to the mixed number 2 & 2/5.
To multiply a decimal number by 101, move the decimal point

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)

Answers
Answer:

I hope I didn't read the question wrong,
1 aspirin 500 miligram, so 5 aspirin=5x500=2500 milligram.
1000mg=1 g
so 2.5 grams aspirin is in the pack.
500mg x 5 = 2500
2500 = 2.5 grams

The Surface Area of cube is 384 inch².
We have,
Edge of the cube = 8 inch
Using the formula of Surface area of Cube
Surface Area = 6(side length)²
So, Surface Area = 6(8)²
Surface Area = 6 x 64
Surface Area = 384 inch²

since we are trying to find how many sales she needs, sales would be our s. She earns 4% of her sales so to find 4% we would multiply the amount of sales by 0.04 (0.04s). She already gets $2,400 a month, so we would add that to what she makes per sale. She is trying to get at least $2,600 this month, so she needs her amount this month to be greater than or equal to $2,600. Hope this helped!!

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
