Therefore, the expression 4y is equivalent to the given expression for the total number of pets.
A small truck can hold a total of 40 crates and boxes. For every 3 crates the truck can hold, there is room for 5 boxes. How many crates and boxes are in the truck when it is completely full?
Answer: There are 25 crates and 15 boxes in the truck when it is full.
Step-by-step explanation:
Let c= Number of crates , b= Number of boxes.
As per given,
[tex]c+b = 40[/tex] (i)
[tex]3c=5b\\\\\Rightarow\ c=\dfrac{5b}{3}[/tex] (ii)
Put value of c from (ii) in (i)
[tex]\dfrac{5b}{3}+b = 40\\\\\Rightarrow\ \dfrac{5b+3b}{3}=40\\\\\Rightarrow\ \dfrac{8b}{3}=40\\\\\Rightarrow\ 8b=3\times40\\\\\Rightarrow\ 8b=120\\\\\Rightarrow\ b=\dfrac{120}{8}=15[/tex]
put value of b in (ii),
[tex]c=\dfrac{5\times15}{3}=5\times5=25[/tex]
Hence, there are 25 crates and 15 boxes in the truck when it is full.
25 boxes 15 crates
We would get this solution by adding up the two sides comparing the ratios, hence: we get room for 3 crates for every 5 boxes that we can hold in the truck.
What are ratios?A ratio is an ordered pair of numbers a and b, written a:b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. hence, if there is 3 crates and 5 boxes you could write the ratio as: 3 : 5 (for every 3 crates there are 5 boxes) 3 / 5 are boys and 5 / 3 are crates.

Answer:
(-1, 0)
Step-by-step explanation:
We want the point (4x, f(4x)) to match (-4, 0). We already know that f(-4) = 0, so we want 4x = -4.
4x = -4
x = -1 . . . . divide by 4
The desired point is (-1, 0).

A box of cereal states that there are 72 calories in a 3 4-cup serving. What is the unit rate for calories per cup? How many calories are there in 4 cups of the cereal?
Answer:
96 calories per cup
384 calories in 4 cups
Step-by-step explanation:
In this scenario, we can use the rule of three to calculate the number of calories in a single cup like so...
72 calories <==========> [tex]\frac{3}{4} cup[/tex] or 0.75 cup
x calories <==========> 1 cup
(1 * 72) / 0.75 = 96 calories
Now we see that there are a total of 96 calories per cup of cereal. In order to find the total amount of calories in 4 cups of cereal, we simply need to multiply the number of calories per cup by 4, like so...
96 * 4 = 384 calories
There are a total of 384 calories in 4 cups of cereal.
At noon, a tank contained 10 cm water. After several hours, it contained 3 cm of water. What is the percent decrease of water in the tank? The percent decrease in water in the tank is nothing%.
Answer:
70%
Step-by-step explanation:
Given that:
Initial water level in the tank at noon = 10 cm
After several hours, water level = 3 cm
To find the percentage change in the water in the tank, we can use the following formula:
[tex]Percentage\ Change = \dfrac{Final\ Value - Initial\ Value }{Initial\ Value}\times 100[/tex]
Here, Final Value = 3 cm
Initial Value = 10 cm
Putting the values in the formula:
[tex]Percentage\ Change = \dfrac{3 - 10 }{10}\times 100\\\Rightarrow Percentage\ Change = -70\%[/tex]
Here, negative value, means there is a decrease in the final value from the initial value.
Therefore, the answer is 70% decrease.

Complete question is;
An ordinary deck of playing cards has 52 cards. There are four suits
-spades, hearts, diamonds, and clubs
-with 13 cards in each suit.
Spades and clubs are black; hearts and diamonds are red. One of these cards is selected at random. Let A denote the event that a red card is chosen.
Find the probability that a red card is chosen, and express your answer in probability notation.
Answer:
P(A) = 0.5
Step-by-step explanation:
We are told that the ordinary deck of playing cards has 52 cards.
Now, there are four suits
-spades, hearts, diamonds, and clubs
-with 13 cards in each suit.
Now, in a standard set of playing cards, there are 13 black spades and 13 black clubs as well as 13 red hearts and 13 red diamonds
Thus;
Number of red cards = 13 + 13
Thus;
Number of red cards = 26
Since, A denotes the event that red card is chosen.
This means that probability of choosing a red card is;
P(A) = number of red cards/total number in a deck of cards
P(A) = 26/52
P(A) = 0.5
When Carla looked out at the school parking lot, she noticed that for every 2 minivans, there were 5 other types of vehicles. If there are 161 total vehicles in the parking lot, how many of them are minivans?
Answer:
46 of the total vehicles are minivans
Step-by-step explanation:
Let the number of minivans be x
and the number of other types of vehicles be y
From the question,
Carla noticed that for every 2 minivans, there were 5 other types of vehicles.
This means the ratio of minivans to other types of vehicles is 2:5.
Therefore,
x:y = 2:5
We can then write that
x/y = 2/5
∴ 5x = 2y ...... (1)
Also from the question,
There are 161 total vehicles in the parking lot
That is
x + y = 161 ...... (2)
From equation (2), we can write that
y = 161 - x
Put this into equation (1)
5x = 2y
Then
5x = 2(161-x)
5x = 322 -2x
5x+2x = 322
7x = 322
x = 322/7
x = 46
Since x represent the number of minivans
Hence, 46 of the total vehicles are minivans.

Answer:
$8
Step-by-step explanation:
5x / 5 = x
40 / 5 = 8
Marisa’s mother contribution was $8 each month.
What is an expression?An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Given that, Marisa’s savings account can be represented by the expression 5x+40. Marisa saved the same amount x each month for a period of 5 months. Her mother contributed an additional amount each month to Marisa’s savings account.
The amount in Marisa's account after 5 months = 5x + 40
She has saved $x each month for 5 months, therefore, her saving = 5x
Her mother given her an additional amount each month which is here shown by 40,
Since, if in 5 months it became 40, therefore, each month mother gave her = 40 / 5 = 8
Hence, Marisa’s mother contribution was $8 each month.

Which function is best represented by this graph?
A. y=1/4x + 8
B. y=1/4x - 2
C. y=4x +2
D. y=4x +8
Answer:
B. y=1/4x-2
Step-by-step explanation:
The -2 in this equation represents the y value. The graph passes through -2 on the y axis, so you automatically cancel out the rest of the answers.
Option B is correct, y=1/4x - 2 is the function which best represented by the given graph.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The line is passing through the points (0, -2) and (4, -1)
Let us find the slope m.
m = -1-(-2)/4
=1/4
So slope is 1/4
Now let us find the y intercept
-2=1/4(0)+b
-2=b
So equation will be y=1/4x-2
Hence, Option B is correct, y=1/4x - 2 is the function which best represented by the given graph.

what is the inverse of the function f (x)=2x+1
Answer:
[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 2x + 1 ( subtract 1 from both sides )
y - 1 = 2x ( divide both sides by 2 )
[tex]\frac{y-1}{2}[/tex] = x
Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus
[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]
