12 = 7w i don't understand how this works

12/7 or 1.71428571429

Step-by-step explanation:

You have to isolate the variable to get the w by itself. It's right next to a 7 which also means 7 multiplied by w. We need to cancel out the seven to isolate the variable so to do this we divide by 7. We also need to do this to the other side of equation to keep it balanced.

-12 = 7w

/7      /7

-1.714...=w

16

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
