Answer:

6(x-4y) = 6x - 24y

Step-by-step explanation:

Here, we want to expand the given expression

We can do this using the distributive approach

We have this as;

(6 * x) - (6 * 4y)

= 6x - 24y

Answer:

Set 1

Step-by-step explanation:

To have a function, you cannot have the same x-coordinate more than once.

In sets 2, 3, and 4, all x-coordinates of each set are different, so they are functions.

In set 1, the x-coordinate 1 appears twice, so set 1 is not a function.

Answer:

Step-by-step explanation:

First you would make 4 4/7 into an improper fraction which you would do by:

7 times 4 is 28 plus 4 is 32.

So the improper fraction is 32/7.

Next you make the denominators the same by finding the least common multiple which is 35.

35 divided by 7 is 5, which also means that 35 divided by 5 is 7.

Then you have to multiply the numerator by the same thing that you multiplied the denominator by.

32 times 5 is 160.

2 times 7 is 14.

So the new problem is 160/35 + 14/35.

You add 160 + 14 which is 174.

So the final answer is 174/ 35 because it can not be simplified any further unless you make it a mixed number which would be: 4 34/35

Answer:

Alex and 5 pages

Step-by-step explanation:

Sammie 25 pages per hour

Alex 1/2 pages per minute

You do 1/2x60=30 because you can find out how many pages he can read per hour.  Which is 30 pages per hour.  So Alex can read 30 pages per hour and Sammie can only read 25 pages per hour.  To find how many pages he reads faster per hour, you have to take 30 and subtract it by 25 to get 5 extra pages.  So Alex reads 5 pages faster per hour.  In the end, Alex reads faster than Sammie by 5 more pages per hour.

Hope this helps!  Please give brainliest.

Answer:

7 and 8

Step-by-step explanation:

Answer:

Step-by-step explanation:

The first step is to find the √58.

The answer is 7.61577310586.

Since this is between 7 and 8, the correct answer is 7 and 8.

Joni pays an annual interest of 5%, which means that in three years, the interest is 15%.

Let us assume that the amount Joni borrowed is m.

After three years, the interest is $30.

15% of the amount m = $30

0.15m = 30

m = 30/0.15 = 200

Therefore, Jodi originally borrowed $200.

The width of the shelf is 10 inches. The correct option is D.

A right-angled triangle is a triangle that has one angle measuring 90 degrees, which is known as the right angle. The sides adjacent to the right angle are known as the legs of the triangle, while the side opposite the right angle is known as the hypotenuse.

The Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs, is one of the fundamental theorems of mathematics and is used extensively in various fields.

Let's call the width of the shelf "x". According to the given diagram, we have a right triangle where the base is x, the perpendicular is 10 inches, and the angle between the hypotenuse and the perpendicular is 45 degrees.

Using trigonometric ratios, we know that:

tan(45) = perpendicular/hypotenuse

tan(45) = 10/x

Since tan(45) is equal to 1, we can simplify the equation to:

1 = 10/x

Solving for x, we get:

x = 10

Therefore, the width of the shelf is 10 inches.

Answer:

No

Step-by-step explanation:

Given b =4, h=6,  H=3, let us find the area.

First we find the area of the triangular face.

(b*h)/2 = 4*6/2 = 24/2 = 12

Then we multiply 12 by the height of the cheese

12*H = 12*3= 36

36 <40, therefore she does not have enough.
