Simplify it by dividing both the numerator and denominator by the same amount. They both must have a result.

For example, we have 8/16.

We can divide it by 2 which gives us 4/8, but it can be simplified more.

We can divide it by 4 this time, which gives us 2/4, but it can still be smaller.

We can divide it by 8 this time, which gives is 1/2. This is the farthest simplification that you can get for 8/16.

Hope this helps

Below

Step-by-step explanation:

You simplify by adding the common factors together, like 3x+4x, which gets 7x. Also the same for subtraction, multiplication, and division.

Find the slope and y-intercept in the equation. 2x+4y=9

const2013 [10]

The first thing to do with these problems is to convert them into y=mx+b form; this will literally show you the answer to slope and y intercept since m=slope and b=y intercept.

To convert, isolate the y and the rest should fall into place. Subtract 2x from 4y and the other side of the equation to get the equation 4y= -2x+9 (put the x first because of mx+b). Then Divide the 4 from y and do the same to the other side to get y= -1/2x+9/4. M= -1/2 so that is the slope. B=9/4 so that is the y intercept

Two planes left simultaneously from the same airport and headed in the same direction towards another airport 3600 km away. The

ExtremeBDS [4]

Answer:

800 kph
600 kph

Step-by-step explanation:

Equation

Let s represent the speed of the faster plane. Then its travel time is ...

time = distance/speed = 3600/s

travel time for the slower plane is ...

time = distance/speed = 3600/(s -200)

The difference in these times is 1.5 hours, so we have ...

3600/(s -200) -3600/s = 1.5

Solution

Multiplying by (2/3)s(s -200), we get ...

2400(s) -2400(s -200) = s(s -200)

s^2 -200s -480000 = 0 . . . . . . . . . . rewrite in standard form

(s -800)(s +600) = 0 . . . . . . . . . . . . . factor

The positive value of s that makes a factor zero is s = 800.

Conclusion

The speed of the faster plane was 800 km/h; of the slower plane, 600 km/h.

_____

Check

The travel time for the faster plane was 3600/800 = 4.5 hours. For the slower plane, 3600/600 = 6 hours, a difference of 1.5 hours.

Assume that there are 2 trials.

vampirchik [111]

Answer: The p(success) = 0.6

Your question is a little unclear, but I believe you are asking about the probability that at least one of the trials in the experiment were successful.

If that is the case, you simply have to add the probability of 1 success with the probability of 2 successes.

That is 0.48 + 0.16 = 0.64

Rounding our answer to one decimal place gives us 0.6.

The ratio of boys to girls in a school is 9:11. If there are 400 pupils in the school,how many boys are there

Anvisha [2.4K]

I believe its 180.

I have seen this question before and the amount of girls was 220, so 400-220 is 180

Hope this helps :)
