Answer:
There are 55 large boxes
and 70 small boxes.
Step-by-step explanation:
Let's assume that the number of large boxes is x, and the number of small boxes is y. We then can use how many pounds each box weighs to form a system of equations.
System:
[tex]50x+25y=4500\\x+y=125[/tex]
Step 1: Solve for a variable
[tex]x+y=125[/tex] is also [tex]y=-x+125[/tex]
Step 2: Substitute
[tex]50x+25(-x+125)=4500[/tex]
Step 3: Simplify
[tex]50x+-25x+3125=4500\\25x=1375\\x=55[/tex]
Step 4: Solve for y
[tex]y=-55+125\\y=70[/tex]

Drag each expression to show whether it is equivalent to 36x+9
or 9(4x−1)
.
Answers
In order to find out what 36x + 9 is equivalent to,, we must factor out 9 from the expression. Once we do this you will find that this expression is equivalent to 9(4x + 1),, or option E.
Next we will look at the expression 9(4x-1). In order for us to find out the equivalent to this expression,, we must first multiply each term in the parenthesis by 9.
9 × 4x - 9
Now calculate the product
36x - 9
This means that the equivalent for this expression is
36x - 9,, or option A.
Lastly,, we will look at the final expression given which is 4(9x + 2). The first step for finding the equivalent of this expression is to multiply the numbers in the first parenthesis together.
(36x) + (4 × 2)
Now multiply the numbers in the second parenthesis together.
(36x) + 8
Remove the parenthesis
36x + 8
Now factor out 4 from the expression to get your final answer.
4(9x + 2)
This means that the last expression is equivalent to 4(9x + 2),, or option C.

Answer:
A movie is $2.5
A video game is $6
Step-by-step explanation:
Pre-SolvingWe are given that Ann had rented 2 movies and 5 video games for a total of $35.
We also know that she also rented 8 movies and 3 video games for a total of $38.
We want to know how much a movie costs, and how much a video game costs.
If a movie costs x dollars, then a video game costs y dollars.
This means that costwise, 2 movies will cost 2x, and 5 video games will be 5y.
8 movies will cost 8x, and 3 video games will cost 3y.
So, we will have two equations:
2x + 5y = 35
8x + 3y = 38
We now have this system of equations, which we can solve.
Let's solve this by elimination.
To eliminate, we need to clear one of the variables, and solve for the other one.
To do this, we need to make sure that one variable has the same coefficient with opposite signs (e.g. -3x and 3x). We might need to multiply one equation by a number in order to achieve this.
We can multiply 2x + 5y = 35 by -4.
-4(2x + 5y) = -4(35)
-8x - 20y = -140
We can rewrite the equations:
-8x - 20y = -140
8x + 3y = 38
They can be added together. The result will be:
-17y = -102
Divide both sides by 017.
y = 6
We found y, but now we need to find x.
We can substitute 6 as y into 2x + 5y = 35 or 8x + 3y = 38 to find x.
Taking 2x + 5y = 35 for instance:
2x + 5(6) = 35
2x + 30 = 35
Subtract 30 from both sides.
2x = 5
Divide both sides by 2
x = 2.5
Recall that x = price of a movie, and y = price of a video game.
Therefore, a movie is 2.5 dollars, and a video game is 6 dollars.
and a snack is $6
Solve for x.

How much money did Rita earn for the time she worked on Monday? Show or explain all of the steps you used to determine your answer.]
Answers
Answer: $158
Step-by-step explanation:
$16(8) + $24(1 ¼) = $128 + $30 = $158
Rita earned a Total of $196 for the time she worked on Monday.
To determine how much money Rita earned for the time she worked on Monday, we need to calculate her earnings for each portion of the day separately.
1. From 8:00 a.m. to 12:00 p.m. (4 hours):
Rita worked for 4 hours within the first 8 hours, so she earns her regular rate of $16 per hour for this time:
Earnings = 4 hours * $16/hour = $64.
2. From 12:30 p.m. to 6:00 p.m. (5.5 hours):
Rita worked for 5.5 hours beyond the initial 8 hours, so she earns 1.5 times her regular rate for each of these hours:
Earnings = 5.5 hours * ($16/hour * 1.5) = $132.
Now, we can sum up Rita's earnings for both periods:
Total earnings = Earnings from the first period + Earnings from the second period
Total earnings = $64 + $132
Total earnings = $196.
Therefore, Rita earned a total of $196 for the time she worked on Monday.

What are the coordinates of the image of (1, 3), where R(−3, 5) is the center of dilation with scale factor 0.5?
PLS ANSWER QUICK
Answers
Answer:
the coordinates of the image D are (-1, 4)
Step-by-step explanation:
To find the coordinates of the image D, we need to apply the dilation transformation centered at R(-3, 5). Let the scale factor be k.
The x-coordinate of D will be shifted k times the distance between 1 and -3, which is 4 units, from the x-coordinate of R, which is -3. So we have:
0.5 = -3 + k(4)
Solving for k, we get:
k = 1.375
Similarly, the y-coordinate of D will be shifted k times the distance between 3 and 5, which is 2 units, from the y-coordinate of R, which is 5. So we have
R: (x, y) = (-3, 5)
D: (x, y) = (-3 + 1.375(1 - (-3)), 5 + 1.375(3 - 5))
D: (x, y) = (-1, 4)
Therefore, the coordinates of the image D are (-1, 4), which is option D.
