Which table shows a constant rate of change?

1. Hours: 2 7 14
Earnings: 40 60 80


2. Hours: 2 7 14
Earnings: 40 140 280

Answer: the answer is 15/14

Answer:what is 3/4÷1/2?

3/2 also know as 1 1/2

Step-by-step explanation:

To do this problem, we have to divide fractions. If you don't know what dividing fraction is I'mgoign to tell you how to do it

How to divide fractions

To Divide fractions, you have to pick the one that is going to be divided and the one that's going to be divided by. Like the dividend and the divisor. Let's say we have 1/2 divided by 1/2.

One important rule in dividing fractions is always flipping the second fraction. If we have 1/2 as the second fraction, we flip it to 2/1 or 2. This action is called the reciprocal.

Once we changed the second fraction to a reciprocal, we multiply the fractions like 1/2 times 2/1 and then we get the answer, 2/2 which equal to one.

If you want, do some practice problems before we do this problem so you can get comfortable with it

1) 2/3 divided by 6/5

2) 4/5 divided by 1/2

3)5/6 divided by 7/8

Now let's get to this problem.

Solving this question

1) Make 1/2 a reciprocal (`2/1)

2) Multiply 3/4 x 2/1

3) The answer is 3/2 or 1 1/2

How to do Negative Addition

Negative Addition is almost like Positive addition. The only catch in Negative Addition is that it is like subtracting. Let me make this clearer. If you draw a number line, with the positives and the Negatives, it will look somewhat like this. (Attachment down below). As you see, the Positives are increasing to the right, but the Negatives are increasing to the left.

When you do addition, you increase right? Like you have 8+4 which is 12. In positive addition you increase to the right, (look on number line). So, if you reverse it to -8+4 you would have to increase to the right, not the left. -8+4 is not -12 because when you add, you increase not decrease. (-12 is smaller than -8 and 4).

So that means -8+4 is -4.

Trick: Subtraction

Another way to think about it is replacing the addition sign to a minus sign then make the negative go away. So, we get 8-4 which is 4. And then we put the negative sign at the 4, so we get -4.

If you don't understand this, plz tell me

Solving your Problem

1) Take out the X to make it simple (Later we are going to add it back

2)Draw a number line to help you (Optional)

3) Use the subtraction Trick (Optional, but imma use it)

4) 6-7= -1 (Make that positive)  

5) The answer is 1x

Answer:

A) 18

B) 48 , 60 and 72

Step-by-step explanation:

A) since the angles are in ratio 2:4:4 there is a constant proportionality that we call k. So the angles can be represented by 2k,4k and 4k. That means 2k + 4k + 4k = 180. K=18

B) The angles would add up to 180 as a general rule, make x the multiplier and

4x+5x+6x=180

15x=180

X=12

Then

4(12)=5(12)+6(12)=180

48, 60 and 72

Answer:

The constant of proportionality is 12.

Step-by-step explanation:

Let's take a look at the formula give to us:

48=4k

First, we have to isolate the variable, K, by dividing 4 on both sides.

48/4=4/4 k

48/4=12

12=k

We can check the answer by plugging it back into the equation:

12*4=48

48=48

Hence, the variable k equals 12.

Answer:

In order to be less then 8

plug in 12 --> 6

plug in 16 --> 7

So 12 and 16

Answer:

1. 50/1 or 50 (other answer is 16 2/3, see explanation to see what I mean)

2. 120/12 or 10

3. 3/10

Step-by-step explanation:

1. 10 ÷ [tex]\frac{1}{5\\}[/tex]

Convert 10 into a fraction

[tex]\frac{10}{1}[/tex] ÷ [tex]\frac{1}{5}[/tex] = [tex]\frac{10}{1}[/tex] x [tex]\frac{5}{1}[/tex] = [tex]\frac{50}{1}[/tex] or 50

(I think you did a Typo and accidentally said three fifths but im going to put it here in case.)

10 Divided by [tex]\frac{3}{5}[/tex]

Convert 10 into a fraction

[tex]\frac{10}{1}[/tex] ÷ [tex]\frac{3}{5}[/tex] = [tex]\frac{10}{1}[/tex] x [tex]\frac{5}{3}[/tex] = [tex]\frac{50}{3}[/tex] or 16 [tex]\frac{2}{3}[/tex]

2. 3 [tex]\frac{3}{4}[/tex] ÷ [tex]\frac{3}{8}[/tex]

Convert 3 [tex]\frac{3}{4}[/tex] into a improper fraction

3 [tex]\frac{3}{4}[/tex] = [tex]\frac{15}{4}[/tex]

Then Divide

[tex]\frac{15}{4}[/tex] ÷ [tex]\frac{3}{8}[/tex] = [tex]\frac{15}{4}[/tex] x [tex]\frac{8}{3}[/tex] = [tex]\frac{120}{12}[/tex] or 10

3. [tex]\frac{1}{2}[/tex] ÷ [tex]\frac{5}{3}[/tex]

[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{5}{3}[/tex]

Turn it into a multiplication problem by turning the multiplier into a reciprocal

[tex]\frac{1}{2}[/tex] x [tex]\frac{3}{5}[/tex] = [tex]\frac{3}{10}[/tex]

Answer:

1 1/3

Step-by-step explanation:

To answer this problem, you need to see how much bigger the sides are in the bigger shape than the smaller one. The side on the left is 12 boxes for the small and 16 for the big. 12 x 1/3 = 4. Now, we can add 4 to 12 and we get 16. If you do the same with the other sides, we get 6 x 1 1/3 = 8 and 3 x 1  1/3 = 4.

Answer:

Y < -2

Step-by-step explanation:

The horizontal line is at -2y. And since the line goes below that means it is less than. Since the line is dashed, it means just less than and not less than or equal.

Answer:

y=2/6x-5

Step-by-step explanation:

This is because the slope is 2/6 using rise/run and the line crosses the y-axis at -5 so the b=-5 thus the equation y=2/6x-5

Your welcome!

Answer:

y = -1/3x - 5

Step-by-step explanation:

slope: -3-(-7)/-6-6 which is 4/-12, reduced is -1/3. The y intercept is -5 so the equation is y = -1/3x - 5
