It takes Francisco 15 minutes to ride his bicycle 4 km, which is the distance
from home to school. What is his
average speed?

i dont know sorry

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

10 x 12 = 120 the tens to conte like 10,20,30,40 so i did that 12 times

x = 3

step-by-step explanation:

you haven't given us any choices but we can guess.

-35x = - 105       divide by - 35

-35x/-35 = -105/-35   the minus signs cancel out and 105 can be divided evenly by 35

x = 3
