Answer:

m = 4

Step-by-step explanation:

12m - 15 = 3 (2m + 3)

12 m - 15 = 6m + 9

12m - 6m - 15 = 6m - 6m + 9

6m - 15 = 9

6m - 15 + 15 = 9 + 15

6m = 24

(1/6) 6m = 24 (1/6)

m = 4

Answer:

6 tickets

Step-by-step explanation:

you can't round it so just says 6 tickets with left over money

The number of tickets Roberto can buy with his $200 is 6 tickets.

The total amount Roberto has to spend on tickets = $200.

The cost of each ticket = $30.

We need to find the number of tickets Roberts can buy for the hockey game.

Total amount to spend on ticket = $200.

Cost of each ticket = $30.

The number of tickets possible to buy with $200 :

= 200 / 30

= 6.67 tickets.

We can not have 6.67 tickets so we can say 6 tickets.

Since each ticket cost $30, the total cost for the ticket is :

= 6 x $30

= $180

So after buying 6 tickets Roberto will be left with $20.

The number of tickets Roberto can buy with his $200 is 6 tickets.

Answer:

Parallelogram

Step-by-step explanation:

Answer:

1-8 would be 1 minus 8, which would give you the answer of -7.

Step-by-step explanation:

For myself, imagine the numbers on a number line, such as on the coordinate plane. Imagine 1(positive 1) plotted on the positive side. "Minus 8 would mean jumping back 8 times, which would bring you to negative 7, or -7.

Answer:

7

Step-by-step explanation:

We know, slope = rise/ run. We can use this slope formula to find out the value of every pizza.

So, 58-25/( 5-2) = 33/ 3= 11

So, every pizza costs $11

Now, A customer pays $80 for a number of pizzas. So, if we divide 80 by 11 we can find the value of unknown number of pizzas he ordered.

So, 80/11= 7.27

Here, pizzas can't be fraction and cost of a delivery fee is added to the cost. So, we can remove the fraction.

So, the customer ordered 7 pizzas for $80.  

Answer:

The simple interest on the given principal after 1 year = Rs. 1,000

The amount Rishav has to pay after an year  = Rs 11,000

Step-by-step explanation:

Here, the Principal amount taken = Rs 10,000

Rate of Interest = 10%

Time Period  = 1 year

Now, the SIMPLE INTEREST  = [tex]\frac{P \times R \times T}{100}[/tex]

or, [tex]SI = \frac{10,000 \times 10 \times 1}{100}  = 1,000[/tex]

So, the simple interest on the given principal after 1 year = Rs. 1,000

Now, Amount = Principal + Simple Interest

or , A = 10,000 + 1,000 =  11, 000

Hence, the amount Rishav has to pay after an year  = Rs 11,000

The value of k that makes the system of equations have no solution is k = -0.25. This is because -0.25 makes the third equation parallel to the first two, resulting in no intersection or solution to the system.

The system of equations provided relates to the concept of systems of linear equations in mathematics. When a system of equations has no solution, it means the graphs of the equations do not intersect. To find the value of k where there is no solution, we determine when the planar coefficients of each equation are proportional. This occurs when the two planes are parallel and hence, do not intersect.

By examining the coefficients, we notice that dividing the coefficients from the first equation by -4 gives us the coefficients of the second equation, meaning the first two equations represent the same plane. Thus, k does not affect the first two equations. For the system to have no solutions, the third plane must be parallel to the first two, meaning the coefficients must have a ratio equal to k. If we set the coefficients from the third equation with the coefficients from the first one, we end with the proportion k/1 = 1/-4 = 3/10. Solving for k gives us a value of -0.25.

Answer:

20 seconds

Step-by-step explanation:

The distance to cover between the lead skater and trailing skater is 40 meters

The lead skater's rate is 12 m/s

The trailing one's rate is 14 m/s

So, we can say:

second skater is accelerating, or covering up the distance, in 14 - 12 = 2 m/s

So, at a rate of 2 meters per second, how long would it take to cover 40 meters??

We use the distance formula, substitute the known and solve for unknown.

Distance Formula = D = RT

Where

D is distance

R is speed/rate

T is time

We know

r = 2 m/s

d = 40 m

t = ?

Now,

D = RT

40 = 2t

t = 40/2

t = 20 (seconds)

Hence,

it will take 20 seconds for the second skater to catch up (pass)

Mara's family's average rate of travel, R, is calculated by dividing the total distance of 239.4 miles by the total time of 4.5 hours and then rounding to the nearest mile per hour.

To determine Mara's family's average rate of travel, R, you should start by calculating the total travel time. They started at 9:10 a.m and ended at 1:40 p.m, which is a span of 4 hours and 30 minutes, or 4.5 hours when converted to decimals to match the units of the distance traveled. Now use the formula for average speed, which is distance divided by time.

So, R = total distance / total time.

Substitute the given values into this formula to arrive at R = 239.4 miles / 4.5 hours. To find the average rate of travel, rounded to the nearest mile per hour, you would complete the division and then round the result.

Example Equation:

R = 239.4 miles / 4.5 hours

Answer:

To find the duration of workout plans A and B offered by Shen, we set up a system of linear equations and solved them. Both plans last 1.25 hours each.

Let us denote the duration of workout Plan A as A hours and Plan B as B hours. We can use the provided information to set up a system of linear equations representing the total training time on each day. On Friday, 3 clients did Plan A and 5 did Plan B for a total of 10 hours, leading to the equation 3A + 5B = 10. On Saturday, 6 clients did Plan A and 2 did Plan B for a total of 10 hours, resulting in the equation 6A + 2B = 10.

To solve this system of equations, we can use substitution or elimination. Multiplying the first equation by 2 gives us 6A + 10B = 20. Then we can subtract the Saturday equation from this to find the value of B:

Now that we know the duration of Plan B, we can plug this into either of our original equations to find the duration of Plan A. Let's use the Friday equation for this purpose:

As it turns out, both workout plans last the same amount of time, 1.25 hours each.

Answer:

The total profit for the six month of Jaxon's business is $335.

Step-by-step explanation:

Here, the profit in the business for the first month = $450

Now, the company suffers for loss of $ 60 per month for 4 months.

SO, the total loss in 4 months = 4 x ( loss in 1 month)

= 4 x ( $ 60)  = $240

So, the combined loss in next four months  = $ 240

Lastly, the profit in the final sixth month of business =  $ 125

So, combined PROFIT in the business = Profit in( First + Sixth)  Month  

                                                       = $ 450+ $ 125 = $575

Total loss in the six months  = $ 240

Now, total profit for the six month of Jaxon's business

= Total Profit - Total Loss

= $575 -  $ 240 = $335

Hence, the total profit for the six month of Jaxon's business is $335.

The equivalent time to 2 h 26 min is 146 min ⇒ 2nd answer

Step-by-step explanation:

Let us revise how to change a time from hours and minutes to minutes

Ex: change 3 h 13 min to min, Multiply 3 by 60 and then

and the answer by 13 [(3 × 60) = 180 + 13 = 193], then

3 h and 13 min = 193 min

Let us do the same with your problem

2 h 26 min

∵ The number of hours = 2

∵ 1 hour = 60 minutes

∴ 2 hours = 2 × 60 = 120 minutes

∵ The number of minutes = 26

- Add 120 to 26

∴ 2 h 26 min = 120 + 26 = 146

The equivalent time to 2 h 26 min is 146 min
