Question 441676
x2+(x+1)2+(x+2)2=50
x2+x2+2x+1+x2+4x+4=50
3x2+6x=45
x2+2x-15=0
(x+5)(x-3)=0
x=-5 or 3
Throwing out the negative answer, we get the numbers to be 3,4, and 5.
----------------------------
x/y=3/4
4x=3y
3(x+4)=4(y-8)
3x+12=4y-32
3x=4y-44
12x=16y-176
9y=16y-176
7y=176
y=25.143
---------------------------
m+n=200
6.50m+4.50n=980
65m+45n=9800
45m+45n=9000
20m=800
m=40
n=160
40(6.5)+160(4.5)=720+260=980..
