1-100
(1+100) (2+99) (3+98)... (50+51)
(101 x 50) = 5050
(4x + 9) - (2x + 7) = 2x + 16, x = 16.
2(16) + 7 = 39
Using line FB, we can find that angle FBC = EFB = 180 - 147 = 33, from the parallel lines. Next, we can see that 4x = x + 33. Simplifying this equation, we then get x = 11.
Oh ok good. Thanks for double checking Pavlov!
Lol
5 x 4. 20
------ = ---------
7 x 9. 63
And there is no way to simplify this.
I'm not 100% sure about this, but if it's per second, then just multiply 60 by 2, and 0.5 by 2 and you get 120 feet per second.
Create an equation:
If minutes = x,
800 - 6x = 1000 - 10x
4x = 200
x = 50
They will become equal at 50 minutes.
3 millimeters : 1 meter
3 millimeters : 1000 millimeters

First list some equations. (x-3) + 41+ (y+8) = 180
(x-3) = 74
Now we have some equations to work with.
74 + 41 + y + 8 = 180
y + 123 = 180
y = 57
Now plug y into the main equation.
x - 3 + 41 + 57 + 8 = 180
x + 103 = 180
x = -77
