3. Andrea is buying snacks at the basketball game. The snacks are $2.25 apiece. She wants to buy 4
snacks. Would the ordered pair (4,9.25) be a solution to this problem? Explain why or why not.
If this is not a solution, provide the correct solution for an x-value of 4.
a) Yes
b) No, the ordered pair (9,4) is a solution to this problem.
c) No, the ordered pair (4, 1.77) is a solution to this problem
d) No, the Ordered pair (4,9) is a solution to this problem.
Answers
Answer:
D - No, the ordered pair (4,9) is a solution to this problem.
Step-by-step explanation:
If you plotted the number of snacks as the x-axis, and then the total cost of the snacks on the y-axis, you would be able to graph a line and see the cost of snacks based on the number purchased. If you were going to write an equation for this, it would be y=2.25x (or y = 2 1/4 x)
In this case, as each snack is the same price, the y-values for each x would be as such: (1, 2.25) <- one snack, $2.25;
(2, 4.5)
(3, 6.75)
(4, 9)
So that is why the ordered pair of (4,9) would be a solution to this problem.
Hope that makes sense!

Step-by-step explanation:
I'm pretty sure that I'm correct. Hope this helps and have a nice day!
Answer:
they have to win 15 games more to have a .500 record
Step-by-step explanation:
If .500 means half,then :
half of 50 games= 25 games
They already won 10
So they need to win 15 more games to have 25 games (half of the 50 games)

Given the equation y= -3x + 2.5 . When x is 0, what value of y makes the equation true?
Answers
Answer:
2.5
Step-by-step explanation:
plug in 0 where x is in the equation to find y
y = -3x + 2.5
y = -3(0) + 2.5
y = 2.5
check it by subbing 2.5 into the y values
2.5 = -3x + 2.5
-2.5. -2.5
0 = -3x
+3x
3x = 0
x = 0
Is-5 a solution to the equation 6x+5=5x+8+2 x? Explain. please help asap
Answers
Answer:
6x+5=5x+8+2x
x= -3
Step-by-step explanation:
use like terms so add 5x+2x=7x
6x+5=7x+8
subtract 5 from both sides
6x+5-5=7x+8-5
simplify
-x = 3
divide both sides by -1
-x/-1 = 3/-1
x= -3
so no -5 is not a solution

Answers
Answer:
(2,-2)
Step-by-step explanation:
Answer:
x = 2, y = -2
Step-by-step explanation:
This means that [tex]-3x + 4 = 4x - 10[/tex]
Now, you just have to solve the equation
[tex]-3x + 4 = 4x - 10\\\\[/tex]
add 3x to both sides
[tex]4 = 7x - 10[/tex]
add 10 to both sides
[tex]14 = 7x[/tex]
divide both sides by 7
[tex]x = 2[/tex]
Substitute this into the equation [tex]y = -3x + 4[/tex]
[tex]y = -3(2) +4\\y = -6 + 4[/tex]
[tex]y = -2\\[/tex]
Alexis divided a 5/12 pound bag of apples among her five friends. How many pounds of apples did each friend receive?
Answers
Answer: 1 /12 pounds each
Step-by-step explanation:
Alexis has a 5/12 pound bag of apples and 5 friends to divide them amongst.
The number of pounds each friend receives is the number of pounds Alexis has divided by the number of friends she has:
= 5/12 ÷ 5
= 5/12 * 1/5
= 5 / 60
Take the fraction to the lowest form by dividing by 5:
= 1 / 12
Hint: When dividing a fraction by a number, you can instead multiply that fraction by the inverse of that number.

on your own paper graph the following equations. describe the graphs and give a solution to the system of equations -2x - 5y = 20 y = 4/5 x + 2
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}-2x-5y=20\\ y=\frac{4}{5}x+2\end{bmatrix}[/tex]
Please check the attached graph.
On the attached diagram:
The blue line represents the line -2x - 5y = 20
The red line represents the line y = 4/5x + 2
It is clear from the graph that both the graphs meet or intersect each other at the point (-5, -2).
In other words,
(x, y) = ( -5, -2) is the point of intersection of the two lines.
We know that the point of intersection of the two lines is the solution of the system of equations.
Therefore, the solution to the system of equations will be:
(x, y) = ( -5, -2)
The solution to the system of equations using the elimination method:
Given the system of equations
[tex]\begin{bmatrix}-2x-5y=20\\ y=\frac{4}{5}x+2\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}-2x-5y=20\\ -\frac{4}{5}x+y=2\end{bmatrix}[/tex]
Multiply -2x - 5y = 20 by 2: -4x-10y=40
Multiply y = 4/5x + 2 by 5: -4x+5y=10
so
[tex]\begin{bmatrix}-4x-10y=40\\ -4x+5y=10\end{bmatrix}[/tex]
now subtracting
[tex]-4x+5y=10[/tex]
[tex]-[/tex]
[tex]\underline{-4x-10y=40}[/tex]
[tex]15y=-30[/tex]
solve 15y = -30 for y
[tex]15y=-30[/tex]
Divide both sides by 15
[tex]\frac{15y}{15}=\frac{-30}{15}[/tex]
[tex]y=-2[/tex]
For -4x-10y=40, plug in y = -2
[tex]-4x-10\left(-2\right)=40[/tex]
[tex]-4x+20=40[/tex]
simplify
[tex]-4x=20[/tex]
divide both sides by -4
[tex]\frac{-4x}{-4}=\frac{20}{-4}[/tex]
Simplify
[tex]x=-5[/tex]
Therefore,
The solution to the system of equations will be:
(x, y) = ( -5, -2)
