Answer:
The three consecutive numbers are 34, 35, 36
Step-by-step explanation:
three consecutive numbers: x+(x+1)+(x+2)
x+x+1+x+2= 105
3x+3=105
-3 -3
3x= 102
3x/3= 102/3
34=x
But we also need to find (x+1) and (x+2)
34+1= 35
34+2=36
34+35+36= 105
The three consecutive numbers are 34, 35, 36
Hope this helps!
Answer:
shorter piece: 2 feet
longer piece: 8 feet
Step-by-step explanation:
let the shorter piece be x
then the longer piece will be 3x + 2
<u>if they join together</u>:
- 3x + 2 + x = 10
- 4x + 2 = 10
- 4x = 10 -2
- 4x = 8
- x = 2
<u>Longer piece</u>:
The equation that represents the relationship between x and y is y= 4x.
