Answer:
Number of pineapples= 10
number of pears = 19
number of kiwis = 10 -2 = 8
Step-by-step explanation:
Cost of a pear = $ 0.50
Cost of a pineapple = $ 1.5
cost of a kiwi = $ 0.3
Let the pineapples = p
Number of pears = 9 + p
Number of kiwis = p - 2
The cost is
0.15 p + 0.5 (9 + p) + 0.3 (p - 2) = 13.50
0.15 p + 4.5 + 0.5p + 0.3 p - 0.6 = 13.50
0.95 p = 9.6
p = 10

Answer:
It took Pedro <em>3.81 hours</em> to reach the lake.
Step-by-step explanation:
Time taken by Mike to hike a lake = 4.5 hours
Average rate of Mike while hiking the lake = 
Formula for distance can be seen as:

Distance traveled by Mike = 
Rate of Pedro while hiking the same distance = 
Given that, Pedro also travels the same distance.
And we have to find the Time.


It took Pedro <em>3.81 hours</em> to reach the lake.
Answer: C. 10.
Step-by-step explanation:
Let x = Number of times you have to go to the gym in order for it to cost the same amount.
Given: Monthly pass fee = $90
Additional charge = $4
Total amount = (Monthly fee) + (Number of times) (Additional charge)
Total amount = 90+4x (i)
Payment for each time you go to the gym = $13
Total amount = 13x (ii)
From (i) and (ii) , we get

Hence, the number of times you have to go to the gym in order for it to cost the same amount= 10
Hence, the correct option is C. 10.
