Answer:

12 cars

Step-by-step explanation:

Ratio 2:3  cars

8:?

To get to 8 from 2, you times by 4, so we do the same on the other side

3 x 4 = 12

8:12

Answer:

B=-2+5 collecting like terms

B=3 answer

Answer:

12

Step-by-step explanation:

(x / 2) + 4 = 10

(x + 2 * 4 ) / 2 = 10

x + 8 = 20

x = 20 - 8

x = 12

or just

x /2 = 10 -4 = 6

x = 6 * 2 = 12

Answer:

x = 12

Step-by-step explanation:

First multiply everything by 2 getting x alone giving you x + 8 = 20 then move 8 to the other side giving you x = 20 - 8 and then subtract giving you x = 12

Answer:

-20x+16 that is the answer

Step-by-step explanation:

Answer:

-20x +16

Step-by-step explanation:

As an equation because you cannot add a constant with a whole number so there is no one answer to you equation. How you can solve is you only need to add combine like terms and the 35 is a negative and not 15 minus 35 but 15x + (-35x). I hope this helps mate ;).

Answer:

2,375,360

Step-by-step explanation:

Answer:

The first group has 20 and the second group has 8.

Step-by-step explanation:

1. Twice as many as 8 is 16  (8x2)

2. If you add four to the total it's 20 (16+4=20)

3. So group one has four more than twice as many as group 2.

Answer:

$27.83

Step-by-step explanation:

15.88+5(.55)+12(.85)=28.83

Answer:

Ann spent $28.83.

Why?

We can find the answer by just multiplying the prices of cookies and doughnuts by their amounts, and adding the total prices together. 0.55 x 5 = $2.75, 0.85 x 12 = $10.20. 2.75 + 10.20 + 15.88 = 28.83. Therefore, Ann spent $28.83.

Answer:

The linear equation is y = -5/8x+15 - Part A

15in - Part B

x = 24 - Part C

Step-by-step explanation:

Part A:

x = number of hours since she filled it

y = amount of ketchup remaining in the bottle

and knowing that we get the points (5, 11[tex]\frac{7}{8}[/tex]) and (8, 10)

Now get the slope of these points.

1. Slope formula

m = y2-y1/x2-x1

2. plug it in and you should get:

m = -5/8

3. Then substitute m = -5/8 and (x1, y1) into the point slope formula then solve for y to write the equation in slope intercept form

4. Point Slope Form = y-y1 = m(x-x1)

y-10 = -5/8(x-8) - substitute

y-10 = -5/8x+5 - distribute

y =  -5/8x+15 -  add 10 on both sides

The linear equation is y = -5/8x+15

Part B:

x represents the hours since she filled it, x = 0 is when she filled the dispenser

= 15in

Part C:

y =  -5/8x+15

0 =  -5/8x+15

5/8x = 15

x = 24

Answer:

770

Step-by-step explanation:

you can do this by doing a proportion: [tex]\frac{4620}{y}[/tex]=[tex]\frac{600}{100}[/tex]

then multiply 4620 by 100 which is 462,000 and divide that by 600 which is 770 so 600% of 770 is 4,620

Answer:

(10,4.6)

Step-by-step explanation:

We need to find the equation for the line first

Find the slope:

m = y2-y1/x2-x1

m = 13 - 7 / -4 - 6

m = 6 / -10

Now we need the y intercept (b)

subtitute one of the points into the equation

y = -6/10x + b

7 = -6/10(6) + b

7 = -3.6 + b

10.6 = b

Now we have the full equation for the line

y = -6/10x + 10.6

and we can input any value into x to find the y of the point

y = -6/10(10) + 10.6

y = -6 + 10.6

y = 4.6

Answer:

(11, 4)

Step-by-step explanation:

Find the slope = rise/ run  or (change in y values)/(change in x-values)

Using points (6, 7) and (-4, 13) ; Slope = (13 - 7)/(-4 - 6) = 6/-10 = -3/5

From this point if the slope is -3/5 this means the rise is -3 and the run 5.

remember that a negative rise you will move down on the rise from the point and a positive run means you will move across from the point.

Using point (6, 7) .

The run is the x movement on a graph so start at 6 and move to the right 5 places,  you in up at  x= 11.

The rise is the y movement on the graph so start at 7 and move down 3 places, you are at y = 4

Point (x, y) on the graph is (11, 4)

to check the problem

you from the slope = -3/5 . If you solve for "b"  in y = mx + b. The equation of the line in slope intercept form is y = -3/5x + 53/5.  Graph  the line and check the point or substitute any value for x and solve for y.

Answer:

The ratios 2.56/32 and 0.48/6 are equivalent; y = 0.08x.

Step-by-step explanation:

$2.56 for 32 oz is a unit price of $2.56/(32 oz) = $0.08/oz

$0.48 for 6 oz is a unit price of $0.48/(6 oz) = $0.08/oz

The unit prices are equal, so the cost of both sizes are proportional.

If x is the weight in oz, multiply the weight by 0.08 to get the cost, y, in dollars.

y = 0.08x

The ratios 2.56/32 and 0.48/6 are equivalent; y = 0.08x.

Using it's concepts, the domain and the range of the function are given as follows:

a) Domain: [0, 7].

b) Range: [0, 300].

The domain of a function is composed by the set of all possible input values of the function. Hence, on the graph, the domain is composed by the values of x.

In the context of this problem, the input of the function is the number of days. A week has 7 days, hence the domain of the function is given by:

[0, 7].

The range of a function is composed by the set of all possible output values of the function. Hence, on the graph, the range is composed by the values of y.

In the context of this problem, the output of the function is the balance of the bank account after each day. Supposing that the smallest balance of the account is of $0, and considering the greatest balance of $300 stated in the problem, the range of the function is given by:

[0, 300].

The graph of the function is incomplete, hence we suppose that the minimum balance is of $0.
