What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The selling price of 2 boxes of cookies = $ 5
So , the cost of 1 box of cookies A = selling price of 2 boxes of cookies / 2
Substituting the values in the equation , we get
Cost of 1 box of cookies A = 5/2
Cost of 1 box of cookies A = $ 2.50
Therefore , the value of A is $ 2.50
Hence , the unit rate of box of cookies is $ 2.50

The quotient of a number x and −1.5 is 21
Answer:
x = -31.5
Explanation:
We are given that the quotient of x and -1.5 is 21
This means that:
[tex]\frac{x}{-1.5} =21[/tex]
To get the value of x, we will multiply both sides of the equation by -1.5
This means that:
[tex]\frac{x}{-1.5} * -1.5=21*-1.5[/tex]
x = -31.5
Note that the value of x must be negative because we are dividing by a negative number and the quotient is positive (-ve/-ve is +ve and +ve/-ve is -ve)
Hope this helps :)
The value of x is -31.5.
Quotient means the result of dividing a number by another number. For example, the quotient of 4 and 2 is 2.
The information provided in this question can be represented with this equation:
[tex]\frac{x}{-1.5}[/tex] = 21
In order to determine the value of x, multiply both sides of the equation by -1.5.
x = 21 x - 1.5
x = -31.5

A 20,000 gallon swimming pool contains 5000 gallons of water when a hose is placed into the pool and begins adding water at a rate of 1250 gallons per hour. Use the Segment tool to plot a graph representing the volume of water in the pool over time from when the hose is placed into the pool until it is full.
20000-5000=15000
15000/1250=12
it will take 12 hours
Solution: The figure 1 shows the graph of the volume of water in the pool over the time from when the hose is placed into the pool until it is full.
Explanation:
It is given that the capacity of the pool is 20,000 gallon and initial water in the pool is 5000 gallons. The remaining capacity of the pool is 15,000 gallons.
The water in the pool increased at the rate of 1250 gallons per hour.
[tex]\frac{15000}{1250}=12[/tex]
So tank will be full after 12 hours.
The initial water in the pool is 5000 gallons and water in the pool increased at the rate of 1250 gallons per hour. So, the volume of water in the pool is described by the equation [tex]V=5000+1250t[/tex].
First we find the value of volume function in different value of t, then plot these points in a coordinate plane and join them with a straight line.
Hence, the coordinate table and graph of the volume function is given below.

a manager purchased a total of 21 coffee mugs and key chains. each coffee mug cost $8.50, and each key chain cost $2.75 . if manager spent total of $132.50, how many coffee mugs did the manager purchase
The manager purchased 13 coffee mugs.
Explanation:To find the number of coffee mugs purchased, we can set up a system of equations. Let's say the number of coffee mugs is represented by x and the number of key chains is represented by y. We have two pieces of information:
1. The total number of items purchased is 21: x + y = 21
2. The total cost of the purchase is $132.50: 8.50x + 2.75y = 132.50
Now we can solve this system of equations to find the value of x, which represents the number of coffee mugs:
Multiplying the first equation by 8.50, we get: 8.50x + 8.50y = 178.50
Subtracting the second equation from this new equation, we get: 8.50x + 8.50y - 8.50x - 2.75y = 178.50 - 132.50
Simplifying, we have: 5.75y = 46
Dividing both sides of the equation by 5.75, we find: y = 8
Substituting this value into the first equation, we can solve for x: x + 8 = 21
x = 13
Therefore, the manager purchased 13 coffee mugs.
