I need help with before 9

Step-by-step explanation:

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.

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]

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

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,

Step-by-step explanation:

Simplify the expression.

Answer

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

height=21in

So, Volume = 8x7x21

1,176in³

Now divide by 392in³

Answer:

Incorrect

Step-by-step explanation:

The formula for slope is [ y2-y2/x2-x1 ] and Emma calculated the slope using the opposite of the formula [ x2-x1/y2-y1 ]. That was her mistake.

Step-by-step explanation:

[tex]3\cdot10^8\dfrac{m}{s}\\\\1km=1,000m\to1m=0.001km\\1h=3,600s\to1s=\dfrac{1}{3600}h[/tex]

therefore

Answer:

The value of the parameter of interest in this setting is:

d. The value of the parameter of interest cannot be determined from the given information.

Step-by-step explanation:

To determine the parameter of interest in this setting, we need information about the population figure of the small-to-medium-sized streams in eastern North Carolina.  We also require the population proportion of these streams, which have runoff from hog farms.  But in this situation, the information is lacking.  Instead, we are given information about the sample, which only produces statistics.  For example, we can calculate the average (mean) proportion of the sample of 242 small-to-medium-sized streams using the 55 that were found to have runoff from hog farms.

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
