Fiona was thinking of a number. Fiona halves the number and gets an answer of 72.8. Form an equation with
x
from the information.

72 = .5x (= 144)

Step-by-step explanation:

A number is denoted as x.

If we half the number, that means we take it times (1/2) or .5.

That leaves us with .5x

Since that equals 72, we can set it equal to 72

.5x = 72

i believe the correct answer is b.

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
