The Value of the Expression

a. 50 times the sum of 64 and 36 ... 50 x (64+36) = 50x (100) = 5000

50 x 64 + 36 )

5000

b. Divide the difference between  1,200 and 700 by 5 ...(1200-700) / 5 = 500/5 = 100

(1,200 - 700): 5

100

C. The sum of 3 fifteens and 17  fifteens ... [tex]\frac{3}{15}[/tex] + [tex]\frac{17}{15}[/tex] = [tex]\frac{20}{15}[/tex] = [tex]\frac{4}{3}[/tex]

45 + 255

d. 15 times the sum of 14 and 6 ... 15 x (14 + 6) = 15 (20) = 300

e.

10 x (250 +45) ...10 times the sum of 250 and 45

For a new customer, a video store charges $10 for a rental card plus $2 per movie. Using the linear equation (y=mx+b) you wrote, find the cost for a new customer to rent 6 movies.

Answers

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.

136 = -8(1 + 6v)
Help

Answers

Use distributive property
136 = -8 + -48v
-8 - 48v = 136
Add 8 to both sides
-48v = 144
Divide both sides by -48
v = -3

Answer:

-3

Step-by-step explanation:

136 = -8(1+6v)

136 = -8 - 48v

136 + 8 = -48v

144 = -48v

144/ -48 = v

-3 = v

(-3/7)x+3=y
Because the y intercept on the graph is 3
And when x is 1 y is 2.5

9514 1404 393

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

Write an equation of the line passing through point P(−8, 0) that is perpendicular to the line 3x−5y = 6.

Answers

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

Jada makes sparkling juice by mixing 2 cups of sparkling water with every 3 cups of apple juice. How much sparkling water does Jada need if she uses 8 coups of sparkling water.

Answers

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.
