Answer:
13 pears in the 21st bag
Step-by-step explanation:
mean = total number of pears/total number of bags
8 = x/21
x = 168
number of pears in 20 bags = (6 x 2) + (7 x 6) + (8 x 9) + (9 x 1) + (10 x 2)
= 155
number of pears in the 21st bag = 168 - 155
= 13
How many miles of gas does my car travel if it used 2 gallons of gas with a speed of 4 mi/h?
R = 2p + 5
r + p < 35
2p + 5 + p < 35
3p + 5 < 35
3p < 35 - 5
3p < 30
p < 30/3
p < 10.....Pat has to be less then 10
minimum age : 7
maximum age : 9
4 (points for an A) x 21 (As) = 84
3 (points for a B) x 24 (Bs) =72
2 (points for a C) x 15 (cs) = 30
84 + 72 + 30 = 186 (total points)
186 divided by 60 (total credits) = 3.1
