Lincoln went into a movie theater and bought 2 bags of popcorn and 4 candies, costing a total of $34. Zoey went into the same movie theater and bought 6 bags of popcorn and 5 candies, costing a total of $74. Determine the price of each bag of popcorn and the price of each candy.
12 each bags
Step-by-step explanation:
2x +4y =34
6x +5y =74
x =34- 4y ÷2
y = $3
x= $ 11
bag each price is $11
The price of one bag of popcorn is $9 and the price of one candy is $4.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Let the price of 1 bag of popcorn = x
And price of 1 candy = y
Given that,
Lincoln buys 2 bags of popcorn and 4 candies for $34
implies that,
2x + 4y = 34 (1)
Also, Zoey buys 6 bags of popcorn and 5 candies for $74
implies that,
6x + 5y = 74 (2)
By solving equation (1) and (2),
x = 9 and y = 4
The price of one bag of popcorn is $9 and the price of one candy is $4.

Hello! Please check the image attached to see the question!
To solve this question, we must break down the question into different scenarios.
The speed expression for the first rider is:
[tex]\begin{gathered} s=\frac{d}{t} \\ \text{let us make the distance the first rider covers as y.} \\ d=y\text{ miles} \\ t=3\text{ hours.} \\ s_1=\frac{y}{3} \end{gathered}[/tex]The speed expression for the second cyclist:
[tex]\begin{gathered} s=\frac{d}{t} \\ the\text{ first rider covered a distance of y miles, the remaining distance } \\ \text{left for the second cyclist to cover is:} \\ (108-y)\text{miles at the same time of 3 hours.} \\ s_2=\frac{108-y}{3} \end{gathered}[/tex]Since one cyclist cycles 3 times as fast as the other:
It is expressed thus:
[tex]\begin{gathered} s_1=3\times s_2 \\ s_1=3s_2 \end{gathered}[/tex]Now substitute the values for the speed expression into the expression above, we will have:
[tex]\frac{y}{3}=3\times(\frac{108-y}{3})[/tex]By solving the above expression, we will get the value of y (part of the distance travelled) and we can get the speed of the faster cyclist.
[tex]\begin{gathered} \frac{y}{3}=\frac{324-3y}{3} \\ y=324-3y \\ y+3y=324 \\ \end{gathered}[/tex][tex]\begin{gathered} 4y=324 \\ y=\frac{324}{4} \\ y=81\text{ miles.} \\ \\ So\text{ the speed of the faster cyclist will be:} \\ _{}=\frac{y}{3} \\ =\frac{81\text{ miles}}{3\text{ hours}} \\ =27mi\text{/h} \end{gathered}[/tex]The speed of the faster cyclist is 27 mi/h.

The equation of a line.
Explanation-:
The slope of the parallel line is also the same.
[tex]m_1=m_2[/tex]Where
m is the slope of a parallel line
The general equation of a line is:
[tex]y=mx+c[/tex]So the equation become is:
[tex]\begin{gathered} y=mx+c \\ \\ y=-\frac{2}{3}x+c \end{gathered}[/tex]The line pass ( 3,4)
That mean,
[tex](x,y)=(3,4)[/tex][tex]\begin{gathered} y=-\frac{2}{3}x+c \\ \\ (x,y)=(3,4) \\ \\ 4=-\frac{2}{3}(3)+c \\ \\ 4=-2+c \\ \\ c=4+2 \\ \\ c=6 \end{gathered}[/tex]So the equation of a line is:

Tom buys some shirts for $15 each. He has a coupon for $9 dollars off the total price. If he pays $36, how many shirts, s , did he buy
We have to find how many shirts (s) he has bought.
We know that each shirt costs $15, so the total cost of the shirts should be 15*s.
If we substract the discount, we have the total final cost C as:
[tex]C=15\cdot s-9[/tex]If we know that this total cost was $36, we can find the number of shirts as:
[tex]\begin{gathered} C=36 \\ 15s-9=36 \\ 15s=36+9 \\ 15s=45 \\ s=\frac{45}{15} \\ s=3 \end{gathered}[/tex]Answer: He bought 3 shirts (s = 3).
Helaine graphed the equation 12x-4y=3 . what was the slope of Helaines line
The slope of Helaine's line is 3
Explanations:Note that:
The slope - Intercept form of the equation of a line is:
y = mx + c
Where m = the slope
c = the intercept
The given equation is:
12x - 4y = 3
Rewrite the above equation in the form y = mx + c
4y = 12x - 3
Divide through by 4
[tex]\begin{gathered} \frac{4y}{4}=\frac{12x}{4}-\frac{3}{4} \\ \\ y\text{ = 3x - }\frac{3}{4} \end{gathered}[/tex]The slope, m = 3
The intercept, c = -3/4
Therefore, the slope of Helaines line is 3

12. Which of the following is a function?(A)(B)(C)(D) {(-5,9), (-2,-5),(1,-5),(5,-2)} (E){(-5,9),(-2,-5),(1,-5).(-5,-2)}
Explanation:
A relation is a function if and only if there is one value of x for different values of y.
This means that if we see repeated x-values then it's not a function. We can see this clearly in the graphs by drawing a vertical line for the values of x. Of the line crosses the graph more than once, then it's not a function.
In every graph the line crosses the graph more than once, so none of these options are functions.
Then, for a set of points we have to check the x-coordinate of each pair. If one repeats in the set, then it's not a function.
In the relation E x = -5 is repeated, so it's not a function. On the other hand, for relation D none of the x-coordinates are repeated. Therefore relation D IS a function
Answer:
Option D is a function

There are x cars and y bikes.
The equation for the total number of vechiles is,
[tex]\begin{gathered} x+y=178 \\ y=178-x \end{gathered}[/tex]In a car, there are 4 vechiles and in a bike there are two wheels. So the equation for the wheels,
[tex]\begin{gathered} 4x+2y=602 \\ 2x+y=301 \end{gathered}[/tex]Substitute (178 - x) for y in the equation 2x + y = 301 to obtain the value of x.
[tex]\begin{gathered} 2x+178-x=301 \\ x=301-178 \\ =123 \end{gathered}[/tex]Substitute 123 for x in the equation y = 178 - x to obtain the value of y.
[tex]\begin{gathered} y=178-123 \\ =55 \end{gathered}[/tex]So number of cars are 123 and number of bikes are 55. So correct option is

Drag the red and blue dots along the x-axis and y-axis to graph 7x+3y=127x+3y=12
Answer:
Explanation:
A linear equation can be graphed in a simple manner. We just have to find two points that lie on the line of the equation and then connect them to produce a line.
Now what two points lie on 7x + 3y = 12?
Well, let us pick a point where x = 0. What is the y-coordinate? Putting x = 0 into our equation gives
[tex]\begin{gathered} 7(0)+3y=12 \\ 3y=12 \end{gathered}[/tex]diving both sides by 3 gives
[tex]\begin{gathered} y=12/3 \\ y=4 \end{gathered}[/tex]Hence a point with x = 0, y= 4 lies on the line. In other words, (0, 4) lies on the line.
We now need to find a second point that lies on the line. How about

The first step is to use a pattern to cut squares from pieces of fabric. Onthe pattern, one side of the square starts at point (5,-4) and ends at point (5,2). If each unit on thepattern is one inch, how many inches long is the side of the square?
Answer:
6 inches
Explanation:
On the square pattern, one side of the square starts at point (5,-4) and ends at point (5,2).
To determine the length of a side of the square, find the distance between the endpoints.
From the endpoints: (5, -4) and (5,2)
The x-coordinates are the same, therefore, the distance between the endpoints is:
[tex]|2-(-4)|=|2+4|=6\text{ units}[/tex]If each unit on the pattern is one inch, the length of a side of the square is 6 inches.
Finds the measures of angle b and d given that m ll n. Explain.
Answer:
b = 60.7
d = 43.1
Explanation:
The angles of measure 60.7 and b are alternate interior angles because they are on opposite sides of the transversal and in the inside of the parallel lines m and n. These angles have the same measure, so
b = 60.7
Angle d and the angle of measure 136.9 form a straight line, so they sum to 180 degrees. Therefore, the measure of angle d is
d = 180 - 136.9 = 43.1
Therefore, the answers are
b = 60.7
d = 43.1
