I didnt cheat I worked hark please dont say I cheated.

Answer:

formula is y=mx+b

the b(y-intercept) is -3x and m(slope) is 9.

In the graph, you would start at -3x on the y-axis (since it's on the y-intercept)

put your dot on -3x and move up 9.

you should land on positive 7(on the y axis)

9 must be a fraction so it would be 9/1

so, move once to the right on positive 7.

sorry couldn't show you.

this is the best I can do

Answer:

Ratio is 1:5; there are 5 times more blue marbles so there should be 10 blue marbles

Step-by-step explanation:

7:35 creates a 1 green marble to every 5 blue marbles ratio. So for every green marble there are 5 blue marbles. If you have 2 green marbles then you have 5+5 blue marbles

Answer:

340

Step-by-step explanation:

Take all sides such as (13x4), (5x12), (5x4), (12x4), then multiply them by the amount of times they are used again, which is twice except for (5x4). So 13x4x2+5x12x2+12x4x2=X.

Answer:

Let's start by using variables to represent the ages of the three people:

Let L be Liz's age.

Let D be Debbie's age.

Let F be Freya's age.

From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:

L = (2/3)D

We also know that Debbie's age is half of Freya's age, so we can write:

D = (1/2)F

To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:

F = 2D

Now we can substitute this expression for F into the equation for Liz's age:

L = (2/3)D = (2/3)(1/2)F = (1/3)F

So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

Answer:

Part A: Your answer is 32.37$

Part B: is 60

Step-by-step explanation:

Part A: So first we do 156 ÷ 12 = 13 then we do 13 x 3.48 = 32.37, Thus the most viable answer would be 32.37$.

Part B: So we first take 208.80 and then we do 208.80 ÷ 3.48 = 60, Thus 60$ is our most viable answer.

Your Welcome!

Answer: a = 60b

Step-by-step explanation: simplifying both sides of the equation, then isolating the variable. So 60 divided by 5 = 12

60a/5 = 12b

well u should know that.....

1. A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other

2. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. A proportion is an equation that states that two ratios or rates are equivalent.

3. As defined in the lesson on Unit Rate and Proportionality, the unit rate is the rate of change in a relationship where the rate is per 1.

4. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)

Since our line is perpendicular to this line, the slope of

our line is the negative reciprocal of 1/4, which is -4/1.

Remember, negative reciprocal is just a fancy way

of saying flip the fraction and change the sign.

So the slope of our line is -4/1 and we use this slope along

with our given point to write the equation of our line.

Start with the point-slope formula.

Y - y1 = m(x - x1).

~Substitute

Y - -2 = -4/1(x - 5).

Minus a negative is plus a positive.

Y + 2 = -4/1x + 20.

Subtract 2 from both sides.

Y = -4/1x + 18

So, our answer is C.

The percent of people of the people surveyed were satisfied with the car is  the percent of people of the people would buy that type of car again, so we have:  2015 ÷ 3100 × 100% = 65%

ANSWER: 65%

Ok done. Thank to me :3

Answer:

2015 / 3100%= 65%

Step-by-step explanation:

You could never tell how many people there are in this world. So that is why the 3100 should have a percentage which is divided by 2015, equals 65%.

Ruth’s new floor cost $432.

The cost can be calculated as follows.

First, calculate the area of dining room. Use the formula of rectangle area (width x length)

Area = width x length

= 6 yd x 9 yd

= 54 sq yd

Second, calculate the total cost.

Cost = 54 sq yd x $ 8 per sq yd

= $ 432

Hence it cost $ 432 to install the new wood floor.

Answer:

$432

Step-by-step explanation:

1. Find the area of the dining room. The equation for finding the area is Length x Width = Area, so, 9x6=54 square yards.

2. Then, since each square yard is $8.00, multiply 54 and 8 to get $432.

21/5 divided by 4/5

When dividing fractions flip the second fraction

21/5 times 5/4

Then multiply across

105/20 = 21/4 or 5.25

Answer:

First blank(reading from top to bottom left to right) : 21 second blank: 21 third blank: 5 fourth blank: 4 fifth blank: 5.25 or 5 and 1/4 or 21/4

Step-by-step explanation:

To solve this you will first need to make 4 and 1/5 into a improper fraction. To do that you multiply 4 and 5 and get 20. Then you add the 1, and get 21. That will go in your first blank. Next you will remember your KCF (Keep Change Flip) rule. Keep the 20/5, change the division sign to a multiplication sign, and flip 4/5 to 5/4. Next you will just multiply across. 21*5=105      5*4=20  The Directions say to have your answer in simplest form. 105/20 is not in it's simplest form. To make 105/20 in simplest form you would just divide. Your answer on a calculator makes out to be: 5.25. That is just 5 and 1/4 in fraction form, or 21/4 in improper fraction form.

Step-by-step explanation:

the meadian score is greater in Judy’s class compared to Ken’s class.

Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.
