In this item, we are basically to get the value of the least number that can be divided both by 6 and 7. In other words, we are to get the least common multiple or (LCM). This is obtained by multiplying the 2 numbers. Thus, after 42 days, they will go golfing the same day again.
68%(plan to go to college) + 14%(plan to start working) = 82%
100% - 82% = 18% (<span>students don't know what they're going to do )
</span>
450 x 0.18 = 81
answer: 81 students <span>are not sure what they are going to do after graduating from high school</span>
4x - (9 - 3x) = 8x - 1
4x - (9) - -(3x) = 8x - 1
4x - 9 + 3x = 8x - 1
7x - 9 = 8x - 1 (-8x from each side)
-x - 9 = -1 (+9 to each)
-x = 8 (divide -1 from each side)
x = -8
