Sleeping bag weights 8 pounds
sb=8

backpack+sleeping bag=31
b+sb=31
sb=8
b+8=31
subtract 8 from both sides
b+8-8=31-8
b+0=23
b=23
backpack weighs 23 pounds with out sleeping bag
equation is b+s=31
s=8

choli [55]

Answer:

Step-by-step explanation:

x+y=10

x=10-y

x=10-5

x=5

3(10-y)= -3(10-y)+30

30-3y= -30+3y+30

30+30-30=6y

From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.
