Answer:
210
Step-by-step explanation:
Formula I made up: (Don't copy it please) (x-1 + x-2 + x-3... until x-(x-1)
Add all answers possible. (4 true and falses with 2 different answers each.) (3 multiple choice with 4 possible outcomes.)
4 x 2 = 8 | 3 x 4 = 12 |
\ /
8 + 12 = 20
Do what I like to call Additional factorial. (it's a little different, so follow the formula above.)
x = 20
20 -1 + 20 - 2... 20-(20-1) = 210
19 + 18... + 1 = 210
Compare my answer to others if you get any because I am just in 8th grade and I am a nerd at math and I love it. Because I am in 8th grade, I have a slight possibility for being wrong. Enjoy the answer and thanks for letting me use my skills for the world. :)
The speed of the 747 jet is 545MPH and the speed of the 787 jet is 530MPH. that means the 747 jet is faster by 15MPH
Answer: (2, -3)
Step-by-step explanation:
To find the the answer, you will need to use the midpoint formula, which is as following:
(x₁+x₂/2, y₁+y₂/2)
Since we have two coordinates, let's substitute them into the equation.
(7 + (-3 )/ 2, (-4) + (-2)/2)
We should first add 7 and -3 together, as well as -4 and -2.
(4/2, -6/2)
We then divide 4 and -6 by 2. This would give us our midpoint coordinate.
(2, -3)
3x+20=7x , then u do 7x minus 3x equals 4x then will have 4x=20 then u divide 20 by 4 and u will get 5 so x=5
