The cost of one sandwich is $3.90
The cost of one deknk is $1.50
hopefully this is correct
The system of equations are
The cost of one sandwich x = $ 3.90
The cost of one drink y = $ 1.50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of one sandwich be x
Let the cost of one drink be y
Now , the equation will be
A customer ordered three sandwiches and two drinks for $14.70
So , 3x + 2y = 14.70 be equation (1)
And , Another customer bought two sandwiches and four drinks for $13.80
So , 2x + 4y = 13.80 be equation (2)
On simplifying the equations , we get
Multiply equation (1) by 2 , we get
6x + 8y = 29.4 be equation (3)
Subtracting equation (2) from equation (3) , we get
4x = 15.6
Divide by 4 on both sides of the equation , we get
x = $ 3.90
So , the cost of one sandwich is $ 3.90
And ,
Substituting the value of x in equation (1) , we get
3x + 2y = 14.70
3 ( 3.90 ) + 2y = 14.70
11.70 + 2y = 14.70
Subtracting 11.70 on both sides of the equation , we get
2y = 3
Divide by 2 on both sides of the equation , we get
y = $ 1.50
So , the cost of one drink is $ 1.50
Hence , the cost of one sandwich and one drink is $ 3.90 and $ 1.50 respectively

Factor Completely:
n^2+8n+15
Answer:
(n+3)(n+5)
Step-by-step explanation:
the common factor between 8 and 15 is 3 and 5. If you add 3 and 5 together, you get 8. If you multiply 3 and 5, you get 15. So using the FOIL method, it should go back to n^2+8n+15

If AB = 24 inches and AB is dilated by a scale factor of
3
5, find A'B'.
Answer:
72in
Step-by-step explanation:
If AB = 24 inches and AB is dilated by a scale factor of 3, then A'B' is gotten by multiplying the AB by the sclae factor as shown;
A'B' = 3AB
A'B' = 3(24)
A'B' = 72 in
Hence the length of A'B' is 72in
Find the circumference and area of a circle to the nearest hundredth. Use 3.14 for pie. Round to the nearest hundredth if necessary. The diameter is 52.
Answer:
Circumference = 163.28 unitsArea = 2,122.64 units²Step-by-step explanation:
Circumference
Circumference of a circle is calculated by the formula:
= π * diameter
= 3.14 * 52
= 163.28 units
Area
Area of a circle is calculated by the formula:
= π * radius²
Radius = DIameter / 2
= 52 / 2
= 26 units
Area = 3.14 * 26 * 26
= 2,122.64 units²

Find the length of midsegment JN in the trapezoid.
Answer:
JN = 18.6
Step-by-step explanation:
Theorem: The length of the midsegment of a trapezoid is the average of the bases.
[tex]JN = \frac{15.4 + 21.8}{2}[/tex]
[tex]= \frac{37.2}{2}[/tex]
= 18.6
See how easy that is when you know the theorem.

Answer:
I believe it might be C. -3
Answer:
The answer is C. -3
Step-by-step explanation:
You could go about solving this mathematically or graphically. I'll explain both ways.
Mathematically: Plug the points into this equation
y(2) - y(1) / x(2) - x(1)
If you do this, it will be -2- 4 / 1 - -1, which equals -6/2. You can simplify this to -3 and there you go.
Graphically: Start on the point (-1,4) and count on the graph until you get to (1,-2) That will be down six units and right two units. This can be written as -6/2, which of course, can be simplified to -3.
I hope this helps.
Tom made fruit punch for a party. He mixed 2 gallons of orange juice, 4 quats of pinnapple juice, 3 pints of cranberry juice. How many quarts did he make in all?
Answer:
13.5
Step-by-step explanation:
Tom made fruit punch for a party
He used the following amount of fruits
2 gallons of orange juice
= if 1 gallon is 4 quart then 2 gallon is 4×2= 8 quarts
3 pints of cranberry juice
= if 1 pint is 0.5 quart then 3 pints is 0.5×3 = 1.5 quarts
The amount of quartz he made can be calculated as follows
= 1.5 + 8 + 4
= 13.5
Hence he made 13.5 quarts of fruit punch
