let x represent the bus

6x + 21 = 195

6x = 195 - 21

6x =174

x = 29

Answer:

29 students in each bus

Step-by-step explanation:

at first, 21 students rode by car. so the remaining students are 195-21=174 students.

Now if we divide the remaining number of students by the number of buses then,

[tex] \frac{174}{6} = 29[/tex]

which is 29 students in each bus.

Answer:

See the attached picture.

Step-by-step explanation:

I had to look up 'balanced hanger' because that was not a term from my own math education, but I found it no problem.

See the attached picture.

There are 2 x's on the left and 4 1's on the right.

This means the equation has 2 x's on the left of the equal sign and 4 1's on the right.

Each unit of different size should be in a different shape.

The idea is that the hanger 'balances', just like a set of scales, or the same way an equation balances both sides.

Hope this helps.

Based on the equation, to eliminate the x terms and solve for y in the fewest steps; the first equation should be multiplied by 3 and the second equation by 5.

6x - 5y = 17

7x + 3y = 11

Using elimination method

18x - 15y = 51

35x + 15y = 55

18x + 35x = 51 + 55

53x = 106

x = 106/53

x = 2

6x - 5y = 17

6(2) - 5y = 17

12 - 5y = 17

-5y = 17 - 12

-5y = 5

y = 5/-5

y = -1

Therefore, the solution to the simultaneous equation; 6x - 5y = 17, 7x + 3y = 11 is x = 2 and y = -1

Step-by-step explanation:

c= 6+s

c=6+5

c=11

(5,11)

Hope this helps! :)

Answer:  B.  (5,11)

Step-by-step explanation:

c  = 6 + 1s          In this case we know that c is your total cost and s is the number of downloaded songs.

If we were to do it in terms of x and y, y will be c, and x will be s.

Now is asking for the cost of 5 songs, so you will input the value 5 into the equation for s and solve for c.

c = 6 + 1(5)

c = 6 + 5

c = 11

Now we know that for 5 songs it will cost you $11, and if x is the same as the number of songs, and y is the total cost then we can say that the point will be,

392in³

Step-by-step explanation:

Volume=base X height divided by 3 OR length X width X height divided by 3

length=8in

width=7in

I believe the answer is x = 2

Answer:

Step-by-step explanation:

First you have to multiply both sides by 4

4 (3x - 1)  by 4 > 3 x 4

Then simplify it:

3x-1 > 12

Now add one to both sides

3x - 1 + 1 > 12 + 1

Then simplify it again:

3x > 13

Now divide both sides by 3

3x ÷ 3 >  13 ÷ 3

Answer:

x = 13 ÷ 3

Answer:

-8x² - 6

Step-by-step explanation:

-1 + 2 will give us "+1"

+1 - 7 will give us "-6"

The answers given already are correct as they are properly matched, so we are left with the following to complete:

Thus,

-4y³ + 4y³ will give us "0".

We would be left with:

-3x² - 6 - 5x²

Collect like terms again

-3x² - 5x² - 6

-3x² - 5x² will give us "-8x²"

Final result would be:

-8x² - 6

Answer:

The relation is [tex]y = -1.5x[/tex]

Step-by-step explanation:

x and y are directly proportional:

This means that the equation is given by:

[tex]y = ax[/tex]

In which a is the multiplier that relates these two variables.

x= -4, y =6

We use this to find a. So

[tex]y = ax[/tex]

[tex]6 = -4a[/tex]

[tex]a = -frac{6}{4}[/tex]

[tex]a = -1.5[/tex]

So

The relation is [tex]y = -1.5x[/tex]
