Maria and Emma each have movie DVD collections.
The number of DVD's in Maria's collection can be represented by x
The number of DVD's in Emma's collection is 3 times the number in Maria's collection.
The total number of DVD's in both collections is 144
What is x the total number of DVD's in Maria's collection?
A=108
B=48
C=72
D=36

So, number of DVDs Emma has is 3x
Given,
x+3x=144
4x=144
x=144/4 = 36

What is the value of x in the following equation?
2/3x+2=4
Answer: 3
Step-by-step explanation: Subtract 2 from both sides, leaving 2/3x=2. All you need to do now is find a number to multiply 2 by to get 6/3, which would be 3. 2=2 is a true statement.
The value of x in the equation (2/3)x + 2 = 4 is x = 3.
We have,
To solve the equation (2/3)x + 2 = 4, we can follow these steps:
- Start by subtracting 2 from both sides of the equation to isolate the term with x:
(2/3)x + 2 - 2 = 4 - 2
(2/3)x = 2
- To get rid of the fraction, multiply both sides of the equation by the reciprocal of (2/3), which is 3/2:
3/2 (2/3)x = 3/2 x 2
x = 3
Therefore,
The value of x in the equation (2/3)x + 2 = 4 is x = 3.

(7m+3)+(7m+6)
I really need help with this
Answer:
Step-by-step explanation:
The parenthesis can cancel because the lack of anything you can do in them, so that will leave you with 7m + 3 + 7m + 6
Next step is to add like numbers, you should start by adding 7m + 7m, which would be 14m.
Next would be to add 3 + 6, which is nine.
To end this equation, simply put 14m + 9
There is no one-number answer because we do not know what m is. So the equation 14m + 9 is the final answer.

Kennith and three of his friends shared a basket of apples. The basket weighed 14.75 pounds. What is the weight of the apples that each of them recieved
Answer:
3.6875 lbs per person
Step-by-step explanation:
Calculation for the weight of the apples that each of them recieved
Based on the information given we were told that Kenneth shared the basket of apples with 3 of his friends which means that they are 4 in total which is Kenneth + 3 of his friends.
Hence,
Weight of apples=14.75 pound/4
Weight of apples=3.6875 lbs per person
Therefore the weight of the apples that each of them received will be 3.6875 lbs per person

An aquarium is being drained. The amount of water in the aquarium, in liters, can be determined by using the function w(x) = 20 - 10 The variable x is the number of seconds after the drain plug is removed. Select EACH true statement about the scenario. The function is a linear equation. The y-intercept of 20 is the initial amount of payater in the aquarium. The slope represents how fast the water is being drained.
Answer:
The answer is all three
Step-by-step explanation:
The function that represents the draining of the aquarium is an illustration of a linear function.
All statements are true about the scenario.
The function is given as:
[tex]\mathbf{w(x) = 20 - 10x}[/tex]
A linear function is represented as:
[tex]\mathbf{y =mx + c}[/tex]
m represents slopec represents the y-interceptBy comparing [tex]\mathbf{y =mx + c}[/tex] and [tex]\mathbf{w(x) = 20 - 10x}[/tex], we can conclude that:
[tex]\mathbf{w(x) = 20 - 10x}[/tex] is a linear equation
The slope of a function is the average rate of a function.
The slope of [tex]\mathbf{w(x) = 20 - 10x}[/tex] is 10
This means that, the aquarium is being drained at a rate of 10 liters per second.
So, we can conclude that, the following statement is also true.
The slope represents how fast the water is being drained.
Lastly, when x = 0, we have:
[tex]\mathbf{w(0) = 20 - 10(0) = 20}[/tex]
This represents the initial volume of the aquarium.
So, we can conclude that, the following statement is also true.
The y-intercept of 20 is the initial amount of water in the aquarium
Hence, the three statements are true.
