Answer:

x=0

Step-by-step explanation:

Simplifying

8x + 5x = 0

Combine like terms: 8x + 5x = 13x

13x = 0

Solving

13x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '13'.

x = 0

Simplifying

x = 0

You can represent the measures of an angle and its complement as x °and (90 - x). Similarly, you can

Tanzania [10]

Answer:

33°
90° -J°

Step-by-step explanation:

If x represents the measure of the angle, its complement is 90-x. The problem statement tells us ...

x +24 = 90 -x

2x = 66 . . . . . add x-24

x = 33 . . . . . . divide by 2

The measure of the angle is 33°.

Using J for x in the given complement relation:

The measure of the complement of J° is (90 -J)°.

In the spinner below the large wedges are twice the size of the smaller ones. What is true about the probability of landing on 6

mr_godi [17]

Answer:

Step-by-step explanation:

If we take each small section to be "1" unit, we can say the large sections (for "2" and "5") are "2" units each. So in total there will be 8 sections.

Since 5 is "2" sections, we can say:

P(5) = 2/8 = 1/4

And 6 is "1" section, so we can say:

P(6) = 1/8

Definitely, Probability of landing a 6 is HALF that of probability of landing a 5. Also we can see this is the picture.

So, from the answer choices, A is right.

Answer:

Step-by-step explanation:

Hello,

First of all we will take any real number x different from 0, -2, +2 as dividing by 0 is not allowed and then we can write

$\dfrac{( - x - 2)}{x(x^2 - 4)}=-\dfrac{x+2}{x(x-2)(x+2)}=\large \boxed{ -\dfrac{1}{x(x-2)}}$

because we know that

$x^2-4=x^2-2^2=(x-2)(x+2)$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
