It does not matter whether or not you have a d or a c to use for an unknown number, because you do not know what that number is. The letter does not abbreviate something, it's just a symbol to fill in the place of the missing number.<span />

Ok so let's start with the definition of variables: variables mean something that gets put in if u don't know the answer it could be a letter number a shape. Does not matter it is something filling in for that missing answer. It is a lot times used in algebra questions you need to find the answer to.

Ok now let's answer your question we'll it does not matter because we'll it is basically just something filling in for a unknown number. So you can figure out it. It does not matter if it is a square d a or 1 just it is filling in for a unknown number.

See what I mean thank you hope I helped

Which of the following are properties of right triangles?

sineoko [7]

The properties that apply true are:

1–as it implies the Pythagorean theorem; a^2+b^2=c^2

3–as it implies the basic rules of visualized geometry.

4–as the greater side(hypotenuse) is opposite the right angle.

NOT 2, as the accrue angles ARE complimentary.

Rainbow [258]

Answer:

The fraction of the students play soccer = $\frac{2}{5}$

Step-by-step explanation:

Given - In the town of Destin, 2/3 of the students in middle school participate in organized sports after school.

To find - If 3/5 of them play soccer, what fraction of the students play soccer? Enter your answer in simplest form

Solution -

Let us assume that,

Total number of students in the middle school = 3x

Now,

Given that

2/3 of the students in middle school participate in organized sports after school.

So,

Total students participated in organized sports = (2/3)×3x

= 2x

⇒Total students participated in organized sports = 2x

Now,

Given that,

3/5 of them play soccer

So,

Total players who play soccer = (3/5)×2x

= 6x/5

⇒Total players who play soccer = 6x/5

Now,

The fraction of total students play soccer = (6x/5) ÷ (3x)

= $\frac{6x}{5}*\frac{1}{3x}$

= $\frac{2}{5}$

∴ we get

The fraction of the students play soccer = $\frac{2}{5}$

The corresponding sides of two similar rectangles are 6 ft and 10 ft. The area of the smaller rectangle is 78 ft2. To the neares

Ira Lisetskai [31]

We know one side of the smaller rectangle, 6ft. Therefore the longer side is 78/6 ft = 13ft.

The ratio of small to large side is 6:10, so the larger rectangles other length is (13 / 6) * 10 ft = 21.666... ft.

Thus the area of the larger rectangle is 21.666... * 10 = 216.666... ft^2, and hence to the nearest whole number it is 217 ft^2

What are the slope and the y-intercept of the line shown in the graph

EleoNora [17]

The y-intercept is the y value when x = 0, or (0 , y)

Based on the graph, your y-intercept is at (0 , 2) or 2

The slope(m) can be found using the slope formula and plugging in 2 points:

$m=\frac{y_2-y_1}{x_2-x_1}$

But if you look at the answer choices, if the slope is positive, the line would be going up and to the right

If the slope is negative, the line would be going down and to the right

your answer is A
