I need to simplify this complex fraction

I see two ways to do it.

First, you have to understand that when you see a 'complex fraction' like this, the top number is a numerator, and the two bottom numbers are both denominators.

Way-1:

Take the top fraction . . . 2/2 . That's equal to 1 . So the whole thing is <em>1/3</em>.

Way-2:

Multiply the bottom two denominators. Then the whole thing is 2/(2·3) . That's the same thing as 2/6 . Simplify that, and you have <em>1/3</em> .

Answer:

Step-by-step explanation:

x/24 = 30/36 simplify

x/24 = 5/6 divide 24 by 6 is 4; multiply 4 by 5

x= 20

(a(1) = 5/3<br> (a(n) = a(n − 1).(-9)<br> What is the 3rd term in the sequence?

nataly862011 [7]

Answer:-30

Step-by-step explanation:

Third term=a3

an=a(n-1) x (-9)

a3=5/3 x (3-1) x (-9)

a3=5/3 x 2 x -9

a3=(5x2x-9)/3

a3=-90/3

a3=-30

There are two spinners. The first spinner has three equal sectors labeled 1, 2, and 3. The second spinner has four equal sectors

zhuklara [117]

<h3>Answer: A) 1</h3>

=========================

Explanation:

Let's label each pair of outcomes as an ordered pair (x,y)

x = first spinner outcome

y = second spinner outcome

We have these 12 different possible combos

(1,3), (1,4), (1,5), (1,6)

(2,3), (2,4), (2,5), (2,6)

(3,3), (3,4), (3,5), (3,6)

Focus on the third column where y = 5 for each (x,y) pair. Of this column only (2,5) has x be an even number. The other results in that column have x be odd.

Basically (1,5) is the only possible outcome if we want the first spinner to lan on an even number, and the second spinner to land on 5.

-6 (6-a) =-84 what is a

Yuri [45]

Answer: A is -8

Step-by-step explanation:

-6 times 6 = -36 then you would do -6 times -a = 6a then you would have

-36 + 6a = -84 then you would add 36 to both sides to get -48 then you would divided -48 by 6 to get -8

Approximate the zeros of the function. Round to the nearest tenth if necessary. f(x) = 4x^2 + 4x - 35. Explain each step on how

svet-max [94.6K]

4x²+4x-35=0
factor: (2x+7)(2x-5)=0
2x+7=0, or 2x-5=0
2x=-7 or 2x=5
x=-3.5 or x=2.5

I don't see any rounding necessary in this case.

when you factor ax²+bx+c, you take the two factors of a and the two factors of c, one factor of a times one factor of c, the other factor of a times the other factors, the sum of the two products make b.
in this case, the factors of 4 is 2 and 2, the factors of -35 is -5 and 7. I line them up in the following way:
2 -5

2 7
then I multiple them diagonally, the top left 2 multiplying the bottom right 7=14, and the other 2 multiplying -5=-10, 14 and -10 make a sum of 4.

if you don't get the desired sum, switch the factors up and down till you have the right combination. Note: Do not switch left and right.

I hope this makes sense to you.
