Answer: x=9, y=26 (9,26)

Using the multiplication and the subtraction property, we can prove that the value of y in the equation given is: 7. (see proof below).

Given the equation, y + 2/3 = 3, to prove that y = 7, we have to solve the given equation in other to find the value of y which must be equal to 7.

(y + 2)/3 = 3 [given]

3 × (y + 2)/3 = 3 × 3 [multiplication property of equality]

y + 2 = 9

y + 2 - 2 = 9 - 2 [subtraction property of equality]

y = 7

Thus, using the multiplication and the subtraction property, we can prove that the value of y in the equation given is: 7.

The average speed required to reach the concert in time is 61 miles per hour.

The average speed required to reach school in time is 27.567 miles per hour.

What is the average speed?

The average speed of an object is defined as the total distance travelled by an object in a particular interval of time or average time. Mathematically, average speed = total distance / total time taken. Its SI unit is m/s.

Calculation of the average speed

We are given that a concert starts in 5 hours and is 305 miles away from the house, i.e. time = 5 hours and distance  305 miles

Then the average speed in miles per hour is given by total distance / total time

Average speed = 305 / 5

= 61 miles per hour

Further, the time taken to reach school is 37 minutes which when converted to hours becomes 37 / 60 hour

The distance between school and home is 17 miles

So, the average speed = total distance / total time

= 17 / (37 / 60)

= (17 × 60) / 37

= 27.567 miles per hour

Hence, the average speed required to reach the concert in time is 61 miles per hour.

The average speed required to reach school in time is 27.567 miles per hour.

The solutions to the absolute value equation given by the word phrase; Absolute value of the quantity one third times x plus 9 end quantity minus 3 equals 21 are; x = −99 and x = 45.

It follows from the task content that the solutions to the absolute value equations as given by the word phrase are to be determined.

Given;

| (1/3)x + 9 | - 3 = 21

Add 3 to both sides;

| (1/3)x + 9 | = 24

Hence, the result equations are; (1/3)x + 9 = 24 OR (1/3)x + 9 = -24.

Therefore, we have;

(1/3)x + 9 = 24

(1/3)x = 24 - 9

(1/3)x = 15

x = 45.

Also, considering the other equation;

(1/3)x + 9 = -24

Subtract 3 from both sides;

(1/3)x = -33

Multiply both sides by 3;

x = -99.

Ultimately, the solutions of the equation are;

x = −99 and x = 45.

Therefore, the solutions to the absolute value equation given by the word phrase; Absolute value of the quantity one third times x plus 9 end quantity minus 3 equals 21 are; x = −99 and x = 45.

An inequality that represents the number of hot dogs per minute joey could eat for the last 9 minutes to break his record is: 9d +  [tex]11\frac{1}{4}[/tex] > 72

For given question,

Joey chestnut is trying to break his own record for eating the most whole hot dogs in 10 minutes.

He needs to eat more than 72 hot dogs to break his record.

After 1 minute, joey has eaten [tex]11\frac{1}{4}[/tex] hot dogs.

let d represent the number of hot dogs joey eats per minute for the next 9 minutes.

9d +  [tex]11\frac{1}{4}[/tex] is the expression that shows how many hot dogs he will eat in total.

9d being how much he'll eat in the remaining 9 minutes, and [tex]11\frac{1}{4}[/tex] being the number of hot dogs he's already eaten in the first minute.

Since it has to beat his former record of 72, it has to be greater than 72. The inequality would be

9d +  [tex]11\frac{1}{4}[/tex] > 72

The amount of Linus's money spent on 200 rounds of arcade game is   $55.

The given question is incomplete, so

Lets suppose that Linus has played 200 round of arcade game and now we will need to determine the amount of Linus's money spent on 200 rounds of arcade game.

Entrance fee of an arcade = $5

Additional cost to play one round = $0.25

With the help of given equation ( C=0.25r+5 )  we will determine the amount of Linus's money spent on 200 rounds of arcade game.

'C' = The relationship between the amount of Linus' money spent

'r'  = The number of rounds of arcade games played

Let's solve the equation now,

As we know that r is number of rounds Linus has played which is 200 rounds.

So,     C = 0.25r+5

          C = 0.25 × 200 + 5

          C = 50 + 5

          C =  $55

Hence, we got that Linus has spent total $55 on 200 rounds of arcade game.
