A class of 195 students went on a field trip. They took 7 vehicles, some cars and some buses. Find the number of cars and the number of buses they took if each car holds 5 students and each bus hold 45 students.

Answers

Answer 1

Answer:

3 cars and 4 buses

Step-by-step explanation:

Let x = cars

Let y = buses

7 vehicles

x + y = 7

cars hold 5 students and each bus holds 45 students

5x + 45y = 195

Solve using subbstitution

x + y = 7

x = 7 - y

5x + 45y = 195

5(7 - y) + 45y = 195

35 - 5y + 45y = 195

35 + 40y = 195

-35             -35

40y = 160

y = 4 (buses)

x + y = 7

x + 4 = 7

x = 3 (cars)

Find four consecutive even integers whose sum is 84. Find the integers.

Answers

Suppose the integers are n , n+2 , n+4 and n+6.
84=n+(n+2)+(n+4)+(n+6)=4n+12.
Subtract 12 from both ends to get.
72=4n.
Divide both ends by 4 to get.
n=18.
So the integers are: 18 , 20 , 22 , 24.

Step-by-step explanation:

Hello There!

When its asking for the vertical intercept its asking " at what points does the equation cross the vertical axis( y axis) so its pretty much asking for the y intercept¨

In the graph shown below the y intercept is 0 so the coordinates of the vertical intercept would be (0,0)

When its asking for the horizontal intercept its asking " at what points does the equation cross the horizontal axis ( x axis ) so its pretty much asking for the  x intercept."

In the graph shown below the x intercept is 0 so the coordinates of the horizontal intercept would be (0,0)

-(4k^2-13k-12)+5k^2-8k How would I be able to write this in standard form with the greatest exponent being first.

Answers

Answer:

Step-by-step explanation:

Negative sign is outside the parenthesis. So, each term of (4k² - 13k -12) should be multiplied by (-1)

-(4k² - 13k -12) + 5k² - 8k = 4k²*(-1) - 13k*(-1) - 12*(-1) + 5k² - 8k

                                        = -4k² + 13k + 12 +5k² - 8k

Combine like terms,

                                        = -4k² + 5k² + 13k - 8k + 12

                                       = k² + 5k + 12

Like terms are the terms with same variable with same exponent.

(-4k² ) and 5k² are like terms

13k and (-8k) are like terms

Teachers divided students into groups of 3. Each group of 3 wrote a report that had 9 pictures in it. The students used 585 pictures altogether. How many students were there in all?

Answers

Answer: 195

Step-by-step explanation:

585/9=65

65*3=195

Answer:

The answer is 195 students.

Step-by-step explanation:

There are 2 solutions for this.

1st solution.

1. Start with the basics, the number of pictures we have altogether, 585.

2. Divide the number 585 by the number of students which is 3 to identify the total number of students that reported the 585 pictures.

3. 585/3 = 195, the total number of students.

2nd solution.

1. Start with the total again, the number of pictures we have altogether, 585.

2. Divide the number 585 by the number of pictures in each group total received pictures which is 9.

3. 585 divided by 9 = 65.

4. Take the number 65 which is the number of groups and multiply it by 3 the number of students in each group which will lead to the answer 195 again.

5. 195 is the number of students in total.

6. Extra: to even re-check your answers, multiply 195 by 3 and u will get 585, because each student did 3 reports.
