Susan began counting backwards from 1298 by 4's saying one number every 5 seconds. At the same time Jim begins counting forward
from 171 by 3's saying one number every 5 seconds what number will they both say at the same time
1 answer:
1298 - 4x =171 + 3x
Add 4x to both sides
1298 = 171 + 7x
Subtract 171 from both sides
1127 = 7x
Divide by 7 on both sides
x = 161
They will both say the number 161 at the same time.
