Answer:

area = l x 5l + 2

Step-by-step explanation:

area equals length times 5 times the length plus two

The expression for the area will be equal to x(5x + 2).

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Flowerbed A has length x feet and width that is two feet more than five times its length

Lenght = x

width = 5x + 2

Area =  L x W

Area = x ( 5x + 2 )

Area = 5x² + 2x

Therefore, the expression for the area will be equal to x(5x + 2).

The proportional relationship is given by y = 8.5x

Two variables are said to be proportion if an increase/decrease in one variable causes an increase/decrease in the other variable.

Let x represent the movie tickets and y represent the cost.

Since x and y are proportional, hence:

y ∝ x

y = rx

Where r is the constant of proportionality.

From the table to find x, when y = 17, x = 2, hence:

17 = 2r

r = 8,5

y = 8.5x

The proportional relationship is given by y = 8.5x

Answer:

21.413

Step-by-step explanation:

Change the divisor 0.63512 to a whole number by moving the decimal point 5 places to the right. Then move the decimal point in the dividend the same, 5 places to the right.

We then have the equations:

1360000 ÷ 63512 = 21.413

and therefore:

13.6 ÷ 0.63512 = 21.413

Both calculated to 3 decimal places.

Explanation:

There are 5 choices for the first selection, 4 choices for the second, etc etc until we reach 1 for the last selection. We have the countdown {5,4,3,2,1}. We'll multiply those values together to get our answer.

5*4*3*2*1 = 120

This operation of starting with some integer, counting down and multiplying along the way, is done so very often that it's given a name which is "factorial". The shorthand notation is to use an exclamation mark. So we'd say 5! = 120

Answer:

[tex]x = \frac{1}{2}y[/tex] or [tex]y = 2x[/tex]

Step-by-step explanation:

Basically, x is 2 times smaller than y, or

y is 2 times larger than x.

For example, when x equals 4, y is 2 times greater, so y = 4 * 2 = 8

Another example:

When y equals 12, x must be 2 times smaller than that, so x = 12 / 2 = 6

I don't know which one you're looking for, but try putting in

x = 1/2y or y = 2x
