two-thirds less than a number

Answers

Answer: X - 2/3

Step-by-step explanation:

x is the number

the number, x, is having 2/3 taken away from it

The keyword less tells you to subtract. So let’s your the variable Y for example. Your going to subtract 2/3 from Y. So that would be Y- 2/3!

The variables y and x have a proportional relationship, and y = 7 when x = 2.
What is the value of y when x = 5?

Enter your answer as a decimal in the box.

y = ___

Answers

Answer:

17.5

Step-by-step explanation:

x=2

y=7

when y by x, then multiple y by 5.

7/2= 3.5

3.5×5= 17.5

you can also do 7x2 which would give you 14 and then divide 7 by 2 to get 3.5, and add the two together, so 14+3.5=17.

Answers

Answer:

a) 9x + 7y = 279

3x + 5y = 135

b) X (Weight of each large box) = 18.75 kilograms

Y (Weight of each small box) = 15.75 kilograms

Step-by-step explanation:

Let's assume:

X is weight of each large box

Y is weight of each small box

First, multiply the opposite number to get the same value of y:

9x + 7y = 279 ..... ×5

3x + 5y = 135 ...... ×7

Second, here comes the outcome of the multiplication from both side:

45x + 35y = 1,395

21x + 35y = 945

24x = 450

x = 18.75 kg

if x = 18.75, then:

3x + 5y = 135

3×(18.75) + 5y = 135

56.25 + 5y = 135

5y = 135 - 56.25

5y = 78.75

y = 15.75 kg

If you try to input the x and y value into the part a) equation, then you will get the same total weight for first and second delivery respectively.

Hope it helps. Thanks!

How does the fact that the points are on opposite sides of the y axis affect the process of finding the distance between the two points?

Answers

Answer:

See below.

Step-by-step explanation:

The fact that the points are on opposite sides of the y-axis does not affect the process of finding the distance between the two points. The distance between two points in a two-dimensional coordinate system can be found using the distance formula, which is based on the coordinates of the two points and does not depend on which side of the y-axis they lie. The distance formula is:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points, and d is the distance between them. The formula involves squaring the differences between the x-coordinates and the y-coordinates of the two points, and then taking the square root of the sum of the squares. The process remains the same regardless of which side of the y-axis the points are located.

Which of the following tables are non-linear?

PLEASE HELP ME :DDDDDDDDDDDDDD

Answers

Answer:

Step-by-step explanation:

To find the area of a rectangle, you multiply the length by the height.

First, we need to convert the mixed numbers to improper fractions:

Length: 6 3/4 ft = (6 x 4 + 3) / 4 ft = 27 / 4 ft

Height: 2 2/12 ft = (2 x 12 + 2) / 12 ft = 26 / 12 ft = 13 / 6 ft

Now we can calculate the area:

Area = Length x Height

Area = (27 / 4) ft x (13 / 6) ft

Area = 351 / 24 ft^2

Area = 14 11/24 ft^2

Therefore, the area of the rectangle is 14 11/24 square feet.

108 is 36% of what number? Write and solve a proportion to solve the problem.

Answers

First write the proportion to find the missing value, which I will replace it with n.
108/n = 36/100
Next write the cross products. So, 36n = 108 x 100 = 10,800
divide each side by 36.
36n/36 = 10,800/36
Lastly simplify. Which will be, n = 300.
so my answer is 108 is 36% of 300.

This is how I was taught:

1. Take the percentage (36%) and change it to a decimal (.36)

2. Set up the equation.

.36x = 108

3. Divide both sides by .36

x = 300
