Answer:

I got 43

Step-by-step explanation:

The first step I took was to make a proportion. I did 9/21 equals x/100. The whole is 21 because it says "Hint: How many players did Clayton play/" so I am guessing it means adding 9 and 12. Then I divided 900 by 21 after using what you would call the butterfly method. I rounded 42.85... to 43.

I hope this helps. This is how I remember it and I got the correct answer. Good luck!

Answer: y=12 x =9

Step-by-step explanation:

In a parallelogram the diagonals bisect each other making them equal.

this means 2y + 6 = 30

we can rearrange this as 30 - 6 = 2y

24 = 2y therefore y = 12

3x - 3 = 24

We can rearrange this as 24 + 3 = 3x

3x = 27

27 / 3 = 9

x = 9

Hope this helped :)

In functions, what does (x+2)(x-4) equate to?

dimaraw [331]

Answer:

f(x) = x^2 -2x -8

Step-by-step explanation:

(x+2)(x-4)

FOIL

first: x*x = x^2

outer: -4x

inner: 2x

last: 2*-4x = -8

Add together

x^2 +2x-4x-8

x^2 -2x -8

This is a parabola

Triangle ABC is congruent to triangle DEF. If DE = 41, EF = 23, DF = 36, and AC = 5x - 9, what is x? Round to the nearest tenth.

Aloiza [94]

Similar shapes may or may not be congruent.

The value of x is (a) 9.0

The corresponding sides are:

AB and DE
BC and EF
AC and DF

The side lengths are:

$\mathbf{DE = 41}$

$\mathbf{EF = 23}$

$\mathbf{DF = 36}$

$\mathbf{AC = 5x - 9}$

Because the shapes are congruent, and AC corresponds to DF.

This means that:

$\mathbf{AC = DF}$

So, we have:

$\mathbf{5x - 9 = 36}$

Collect like terms

$\mathbf{5x = 9 + 36}$

$\mathbf{5x = 45}$

Divide both sides by 5

$\mathbf{x = 9.0}$

<em>Hence, the correct option is (a) 9.0</em>
