Hi!
1/4 of 20 pencils are 5 pencils.
Since he gave away 4 pencils,
Total = 5 + 4 = 9
Mr. Simms use and give away total 9 pencils.
6y - 4(y - 1) +6
6y - 4y -4(-1) + 6
6y - 4y +4 + 6
2y + 10
The answer is C : x = 2 rad 2 and y= 2 rad 3
3.5 hours each.... 7hrs if work/2 people = 3.5 hrs of work each
120 - 22 = 98. 98 / 15 = 6.533333. Because you want the minimum, and he can't get paid during 0.53333 of a week, Tom must walk the dog for a minimum of 7 weeks.
