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
This you answer x=-1/5y+-4/5

Answer:
12xy(3y-4x)
Step-by-step explanation:
Answer:
x = - 7.5
y = 11.1
Step-by-step explanation:
3x + 5y = 27
- 7x - 5y = 3
add the two equations
- 4x = 30
divide by - 4
x = - 7.5
plug x into an equation to find y
- 7 ( - 7.5 ) - 5y = 3
52.5 - 5y = 3
subtract 52.5
- 5y = - 55.5
divide by - 5
y = 11.1
