e: gtfo ub1quitous
Ima get my maths exam
e:
240 25kg
110 18kg
e: FIRST
MMMMMMOAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRRRRRR
x + y = 350
y= 350-x
7980 = x25 + (350-x)18
= x25 + 6300-18x
7x + 6300 = 7980
7980 - 6300 = 1680
7x = 1680
x = 240
350 - 240 = 110
240 25kg
110 18kg
x1+x2=350
x1= 350-x2
(350-x2)*25 + x2*18 = 7980
8750 - x2*25 + x2*18 = 7980
- x2*25 + x2 * 18 = -770
x2 * (-25 + 18) = -770
x2 = 110
x1 = 240
edit: was calculating when you posted ><
e: 7!! you obv cant count, you cheated on this test!! :D
e: What ? I did it correct, u went under 0
110*18kg
uh, im too late
v = 18
x*u + y*v = 7980
x + y = 350
x = 350 - y
u(350-y) + v*y = 7980
350u -uy +vy = 7980
350u + y(v-u) = 7980
y = (7980-350u)/(v-u) = 110
x = 240
