A culinary club earns $1116 from a dinner service. They sold 32 adult meals and 60 student meals. An adult meal costs twice as much as a student meal.
What is the cost of an adult meal? Please explain and show all steps! The answer is 18, but I don't get how.
Answers
Second 18 divided by 2 = 9
Third 9 x 60 = 540
Fourth 540 + 576 = 1116
Fifth Cost of adult meal 18
Sixth Cost of Student meal 9
Answer:
$18
Step-by-step explanation:
Let x represent the cost of an adult meal (the value we want to know). The cost of a student meal is half that, or x/2. The total cost of all the meals is ...
60(x/2) +32x = 1116
62x = 1116 . . . . . collect terms
x = 1116/62 = 18 . . . . divide by 62
The cost of an adult meal is $18.
_____
Additional comment
You can instead use a variable for the cost of a student meal, or you can use variables for both:
a = 2s
32a +60s = 1116
It makes sense here to solve this by eliminating the s variable in any of several ways, since you ultimately want to know the value of 'a'.

x<2.1 is the simplified inequality.
What is an inequality?An inequality is an inequation separated by <,>≥,≤. In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”
Given here: The inequality -4x>8.4
multiplying by -1/4 both sides we get
4x/4 < -8.4/4
x<-2.1
Hence, x<2.1 is the simplified inequality.

We are told the cost of the fabric per meter, so we first need to convert 250 cm into meters.
1 meter = 100 cm
Therefore, 250 cm = 250 ÷ 100 = 2.5 meters
cost of fabric = $15.40 per meter
To calculate the total cost, mulitply the length in meters by 15.40:

Please hurry on an exam The formula for calculating simple interest is I = prt. Which is the equivalent equation solved for r?
StartFraction I Over p t EndFraction = r
StartFraction p t Over I EndFraction = r
I minus p t = r
I + p t = r
Answers
Answer:
r=I/pt
Step-by-step explanation:
I = PRT is the formula for interest, and we need to solve it for R. Since all three of P, R, and T are multiplied, we send things to the other side of the equals through dividing. I = PRT I / P = RT to divide both sides by P I / PT = R to divide both sides by T So I / PT = R (the first choice) is the equation solved for R.

Describe the relationship between the number of feet and the number of yards.
Write an expression for the number of yards in f feet.
Find the number of yards in 63 feet.
Answers
Answer:
answer:
1Yarda = 3 feet
y = (1/3) f
y = 21
Step-by-step explanation:
The first thing we should do is see what relationship we have:
Table is feet to yards 3-1
a. Describe the relationship between the number of feet and the number of yards
That is to say:
1Yarda = 3 feet
b. Write an expression for the number of yards in f feet
Let
y = Yard
f = feet
We have the following expression for the conversion:
y = (1/3) f
c. Find the number of yards in 63 feet
For this case we must substitute in the expression found the value of f = 63.
y = (1/3) f
y = (1/3) (63)
y = 21

Answer:
There are 3 feet per yard
# of yards = 3f
189 feet
Step-by-step explanation:
f = feet
y = yard
First Question: Dividing the # of feet by # of yards for one column will always equal 3. So there are 3 feet per 1 yard
Examples: 3/1=3, 6/2=3, 9/3=3 ...
Second Question: To find the number of yards, divide the number of feet by 3. In other words, f/3=y
Third Question: Using the expression f/3=y, there are 21 yards in 63 feet
Prosses:
f/3=y
63/3 = y

First, rotate 180° counterclockwise around the origin. Then reflect across the x-axis.Figure: Third graph
First translate 9 units to the left. Then reflect across the x-axisFigure: First graph
What is the method to determine the transformation of an image?The coordinates of (x, y) following a reflection across the x-axis is (x, -y)
The coordinates following a reflection across the y-axis is (-x, y)
here, we have,
The points of the triangle following the first transformation is therefore;
(4, 4) → (4, -4) → (-4, -4)
(8, 4) → (8, -4) → (-8, -4)
(6, 6) → (6, -6) → (-6, -6)
The image from the first transformation is (-4, -4), (-8, -4), (-6, -6), which
corresponds to the second graph.
The coordinates following a rotation of (x, y) by 180° about the origin is (-x, -y)
A reflection of the point (-x, -y) about the x-axis is (-x, y).
Therefore;
(4, 4) → (-4, -4) → (-4, 4)
(8, 4) → (-8, -4) → (-8, 4)
(6, 6) → (-6, -6) → (-6, 6)
The image from the second transformation is (-4, 4), (-8, 4), (-6, 6), which corresponds to the third graph.
The coordinates following a translation of 9 units to the left is (x - 9, y)
A reflection of the point (x - 9, y) about the x-axis is (x - 9, -y)
Therefore;
(4, 4) → (4 - 9, -4) = (-5, -4)
(8, 4) → (8 - 9, -4) = (-1, -4)
(6, 6) → (6 - 9, -6) → (-3, -6)
The image from the third transformation is (-13, -9), (-1, -4), (-7, -6), which corresponds to the first graph.

Mia paddled her canoe from the shore of a lake to an island. She stopped on the island to eat lunch, and then paddled her canoe back to the shore. The graph below shows Mia’s distance, in kilometers, from the shore over time. Based on the graph, which of the following statements is true?
Answers
It took Mia 40 minutes to get to the island, 30 minutes eating lunch, and 30 minutes back.
The speed of Mia on the way back to the shore is greater than speed on the way to the island
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the speed on the way to the island be S₁
Let the speed on the way back to the shore be S₂
where the Speed = Distance / Time
So , S₁ = ( 3 - 0 ) / ( 40 - 0 )
S₁ = 3/40 km/minutes
S₁ = 0.075 km/minutes
And , S₂ = 0.1 km/minutes
Now , S₂ > S₁
Hence , the speed on the way back to the shore is greater
