1/8x+3y=3
subtract 1/8x from both sides
3y=-1/8x+3
divide both sides by 3
y=-1/24x+1
ANSWER: the slope should be -1/24
Answer:
-2 > x
Step-by-step explanation:
Hello,
We don't need algebra to solve this.
I suppose the ages are 1,2,3,4
Their sum is 1+2+3+4=10.
To obtain 94 we must add 94-10=84 for 4 persons =>84/4=21 to each
Ages are
1+21=22
2+21=23
3+21=24
4+21=25
But if really want an algebric resolution:
Let's x the age of the youngest
x+1,x+2,x+3 the others.
x+(x+1)+(x+2)+(x+3)=94
==>4x+6=94
==>4x=88
==>x=22
Ages are 22,23,24,25.
The oldest friend is 25 years old.
180=(9X-11)+(4X+1)+(7X-3)
180=20x-13
193=20x
9.65=x
