Step-by-step explanation:

1/3 x 20 is equal to 6 2/3 or 20/3.

To solve the expression 1/3 x 20, you multiply 1/3 by 20.

The correct approach is to leave the fraction as it is and perform the multiplication.

Here's how you can calculate it:

1/3 x 20 = (1/3) x 20

To multiply fractions, you multiply the numerators (the numbers on top) and the denominators (the numbers on the bottom). So, in this case:

(1/3) x 20 = (1 x 20) / 3

Multiplying 1 by 20 gives us 20, and the denominator remains the same.

Therefore:

(1/3) x 20 = 20/3

The result, 20/3, is an improper fraction.

If you prefer, you can also express it as a mixed number by dividing the numerator (20) by the denominator (3):

20 ÷ 3 = 6 remainder 2

So, the final result can be written as:

20/3 = 6 2/3

Therefore, 1/3 x 20 is equal to 6 2/3 or 20/3.

Answer:

what is this

Step-by-step explanation:

Answer:

4 cans of soup and 2 frozen dinners.

Step-by-step explanation:

Let the can of soup = x

Let frozen dinner s = y

Davis wants to the grocery store and purchased cans of soup and frozen dinners.

Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium.

David Purchased twice as many cans of soup as frozen dinners and they all collectively contain 2100 mg of sodium.

x = 2y

Hence:

250x + 550y = 2100

250(2y) + 550y = 2100

500y + 550y = 2100

1050y = 2100

y = 2100/1050

y = 2

Since

x = 2y

x = 2 × 2

x = 4

Hence,

the can of soup = x = 4

Let frozen dinner s = y = 2

Davis bought 4 cans of soup and 2 frozen dinners.

22.5 yards

hope it helps!

The amount of bronze yarn is 52.5 yards in the magic carpet.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Given carpet is made with 3 colors of yarn with a ratio of: 5 yards gold : 3.5 yards bronze : 1.5 yards silver

There are 10 pieces of yarn in total. This signifies that 3.5 yards of the carpet are bronze.

To compare this to the 150 meters of total yarn, use the following equation:

⇒ 3.5/10 = x/150

⇒ After that, you cross multiply:

3.5×150 = 10×x or, more simply, 525 = 10x

Then, divide both sides by 10 to get x on its own.

Because 525 /10 = 52.5, x equals 52.5.

This equates to 52.5 yards of silver in the carpet.

Therefore, the amount of bronze yarn is 52.5 yards in the magic carpet.

Step-by-step explanation:

divide then subtract

The dimensions of the rectangular enclosure for his garden is length of 7.5 m and width of 7.5 m.

Let x represent the length of the garden and y represent the width of the garden.

Perimeter = 2(x + y)

30 = 2(x + y)

x + y = 15

y = 15 - x

Area (A) = length * width

A = xy

A = x(15 - x)

A = 15x - x²

Maximum area is at dA/dx = 0:

dA/dx = 15 - 2x

0 = 15 - 2x

2x = 15

x = 7.5 m

y = 15 - x = 15 - 7.5 = 7.5 m

The dimensions of the rectangular enclosure for his garden is length of 7.5 m and width of 7.5 m.

Step-by-step explanation:

Answer: is not / is one x-value

Step-by-step explanation:

The relation is not a function because there is one x-value corresponding to multiple y-values.

For a function, each point on the domain is mapped into only one point on the range.

In this relation we can see the points:

(1, 4), (3, -1), (-1, -2), and (1, -3).

Then we can see that the element of the domain "1" is being mapped into two different elements of the range (4, and -3).

Then the relation is not a function because there is one x-value corresponding to multiple y-values.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation is,

⇒ 3x² - 5x - 2

Now, We can factor the expression as;

⇒ 3x² - 5x - 2

⇒ 3x² - (6 - 1)x - 2

⇒ 3x² - 6x + x - 2

⇒ 3x(x - 2) + 1 (x - 2)
