There were 5 boys for every 8 girls at Foster High School last year. If there were 390 students at the school, how many were girls and how many were boys?​

Answer:

35)The way to solve this is by making the decimal a fraction, 6tenths equals 6/10.

Now we find a common denominator,lets use 30.

multiply the 6/10 by 3 to get 18/30

multiply 2/3 by 10 to get 20/30

2/3 is greater than 0.6

Answer:

1/4 +6<t-3

Step-by-step explanation:

the answer is tahta

Answer: I think it is the first answer

Step-by-step explanation:

Group A = < Group B

Group A has 6 more than total so 1/4t+6

Group B has 3 less than total so t-3

Given:

Charges for rental card = $10

Charges for movie = $2 per movie

To find:

The linear equation for given situation and find the cost to rent 6 movies.

Solution:

Let y be the total cost for x number of movies.

Cost of one movie = $2

Cost of x movies = $2x

Total cost = Charges for rental card + Charges for x movies

[tex]y=10+2x[/tex]

Put x=6 to find the cost of 6 movies.

[tex]y=10+2(6)[/tex]

[tex]y=10+12[/tex]

[tex]y=22[/tex]

Therefore, the total cost for a new customer to rent 6 movies is $22.

Answer:

y = mx + b

Step-by-step explanation:

Answer:

y = -5/3 * x - 40/3

Step-by-step explanation:

A perpendicular line has an opposite and a reciprocal of the slope.

Your equation should be:

-5y = -3x +6

Divide all parts by -5.

y = 3/5x - 6/5

Since the perpendicular line has an opposite and a reciprocal of the slope, the slope will be -5/3.

Now you must make an equation in point-slope form. This is an example of that form. You will need at least one point to make this equation work. In this case we have (-8,0).

In put the y and x coordinates like this:

y - 0 = -5/3(x - (-8)

Start solving the equation.

y - 0 = -5/3(x + 8)

y - 0 = -5/3 * x - 40/3

y = -5/3 * x - 40/3

This is your equation.

y = -5/3 * x - 40/3

(You can make it -5/3x in your answer but it looks weird online. You may think that it is -5 divided by 3 times x, but it actually is 5/3 times x. That's why I wrote it as y = -5/3 * x - 40/3)

Answer:

  5x +3y = -40

Step-by-step explanation:

When the equation of a line is given in standard form, the equation of the perpendicular line can be found by swapping the coefficients of x and y, and negating one of them.

Here, that means the equation ...

  3x -5y = constant

becomes

  5x +3y = new constant

The value of the new constant is found by putting the given point coordinates in the expression on the left:

  5x +3y = 5(-8) +3(0) = -40

The equation of the perpendicular line is ...

  5x +3y = -40

Answer:

Step-by-step explanation:

2 cups of sparkling water with every 3 cups of apple juice = sparkling juice

Sparkling water : apple juice

2 : 3

How much sparkling water does Jada need if she uses 8 cups of apple juice.

Sparkling water : apple juice

x : 8

Equate both ratios

2 : 3 = x : 8

2/3 = x / 8

2*8 = 3*x

16 = 3x

x = 16 / 3

= 5.33 cups

Sparkling water = 5.33 cups

How much apple juice does Jada need if she uses 8 cups of sparkling water

Sparkling water : apple juice

8 : y

Equate both ratios

2 : 3 = 8 : y

2/3 = 8 / y

Cross product

2 * y = 3 * 8

2y = 24

y = 24 / 2

= 12

y = 12

Apple juice = 12 cups

NOTE: There is an error in your question, you wrote "How much sparkling water does Jada need if she uses 8 coups of sparkling water." but I solved for both sparkling water and apple juice using 8 cups since your question was not clear enough.

Answer:

  y = (-7/3)x +3

Step-by-step explanation:

The line has a negative slope (eliminating choices B and C) that is steeper than a line with a slope of -1, The only answer choice with a negative slope less than -1 is choice D.

__

The slope is the coefficient of x. It is "rise"/"run". Here, the line goes through grid points (0, 3) and (3, -4), so drops 7 units (rise=-7) for each 3 units to the right (run=3). Then the slope is rise/run = -7/3.

The line crosses the y-axis at y=3, so the slope-intercept equation is ...

  y = mx + b . . . . . . . . slope = m; y-intercept = b

  y = (-7/3)x +3

-1/3(px-2) = 9

ok! so first we want to isolate x.

multiply both sides by -3/1 (this is the reciprocal of -1/3)

(px-2) = -27

px = -27 + 2

px = -25

x = -25/p

Answer:

f=  

23/14

=1.643

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-11-(7*(1-2*f)+5)=0

-11 -  (7 • (1 - 2f) +  5)  = 0

14f - 23  = 0

3.1      Solve  :    14f-23 = 0  

Add  23  to both sides of the equation :  

                     14f = 23

Divide both sides of the equation by 14:

                    f = 23/14 = 1.643

Answer:

Step-by-step explanation:

136 = -8(1+6v)

144/ -48 = v

-3 = v

Answer:

962.5 is the answer

Step-by-step explanation:

One gallon cost 2.5 dollars and according to this 1*2.5=2.5+2*5=10........

The relationship between no. of gallons and the total cost of purchasing is in a linear relationship.

A linear relationship between two variable is when one variable is increased or decreased by some constant this results in same amount of increase or decrease in the another variable.

According to the given data

The relationship between the number of gallons of gas that are purchased and the total cost is in linear relationship.

A linear relationship forms when increasing a variable k times results in increase of k times on the another variable and same is for decrease.

We can observe when x = 1, y = 2.5.

Now suppose k is 10

∴ x = 1k and y = 2.5k

  x = 10 and y = 25. Which is already given in the diagram showing a linear relationship.
