The solution of the given expression if p = 1, r= -7, and s = -2 will be; -5 and 1/2

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

WE have been given an expression as

-3p-2r / 6+4s

We have to substitute the value p = 1, r= -7, and s = -2 to find the solution.

Plug the values;

-3p-2r / 6+4s

-3 (1) -2 (-7) / 6+4(-2)

-3 + 14 / 6 - 8

11 / -2

Hence, the solution of the given expression if p = 1, r= -7, and s = -2 will be; -5 and 1/2

Answer: $36

Step-by-step explanation:

Let the total amount of money that he had in the beginning be represented by x.

Since Gary spent 1/6 of his money on baseball cards which was $6. This will then be solved further as:

1/6 × x = 6

1/6x = 6

x = 6 × 6

x = 36

The total amount of money that he had in the beginning was $36

Answer:

Step-by-step explanation:

For plane A,

Equation that represents the relationship between time 'x' and distance 'y' is,

y = 470x

By comparing this equation with the slope-intercept form of the equation,

y = mx + b

m = slope = 470

b = 0

Here, slope represents the speed of plane A.

Therefore, speed of plane A = 470 mi per hour

For plane B,

From the given table,

Slope of the graph = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

                                = [tex]\frac{960-480}{2-1}[/tex]

                                = 480

Speed of plane B = 480 miles per hour

Since, speed of plane B is more than plane A,

Plane B is flying faster.

Answer: y = -2 + 3/2x

Step-by-step explanation:

1. 3x - 2y = 4 (move the variable to the right of the equal)

1.1. -2y = 4 - 3x

2. y = -2 +3/2x (divide both sides by -2)

Answer:

[tex]3.2\:\text{hours}[/tex] is spent playing dance music.

Step-by-step explanation:

Given: During [tex]24[/tex] hours a radio station spends [tex]\frac{1}{5}[/tex] of the time playing rock music, [tex]\frac{2}{3}[/tex] playing hip hop, and the rest playing dance music.

To find: How much time is spent playing dance music?

Solution:

We have,

Radio station spends [tex]\frac{1}{5}[/tex] of the time playing rock music.

Radio station spends [tex]\frac{2}{3}[/tex] of the time playing hip hop.

Radio station spends rest of the time playing dance music.

So,

Time spend on playing rock music [tex]=\frac{1}{5}\times24 = 4.8\:\text {hours}[/tex]

Time spend on playing hip hop [tex]=\frac{2}{3}\times24 = 16\:\text {hours}[/tex]

Now, total time radio station spends on all the three music is [tex]24[/tex] hours.

Therefore, rest of the time[tex]=24-(16+4.8)=3.2\:\text{hours}[/tex]

It is given that in the rest of the time, the radio station plays dance music.

Hence, [tex]3.2\:\text{hours}[/tex] is spent playing dance music.

Time taken to complete the race

= Distance / Speed

= 56 miles / (14 miles/hr)

= 4 hours. (B)

Answer:

B. 4 hours

Step-by-step explanation:

If the distance is total of 56 miles and he travels 14 miles per hour,

divide 56/14

56/14=4

4 hours to complete the 56-mile race

Answer:

1.5x ≤ 60

Step-by-step explanation:

He wants to run no more than 60 minutes a day

No more than means Less than or equal to with the inequality sign of ≤

Each lap = 1.5 minutes.

The greatest number of laps Peter could run = x

Therefore, the inequality that best represents the situation and represents x, the greatest number of laps Peter could run in a day

1.5 × x ≤ 60 minutes

= 1.5x ≤ 60

Solving for x

1.5x ≤ 60

x ≤ 60/1.5

x ≤ 40 laps

Hence, the Greatest number of laps = x that he can run is 40 laps
