False because -5/11 should be add on both sides
Answer:
x = 9
Step-by-step explanation:
given f(x) = 3x and f(x) = 27, then equating f(x) gives
3x = 27 ( divide both sides by 3 )
x = 9
Answer:
686 crystals.
Step-by-step explanation:
You can set up an algebraic equation to find the answer.
Let x represent the number of crystals Lily uses.
The question is asking how many crystals it will take to raise 6,174 zombies, when each crystal raises 9.
9x = 6174
x = 6174 / 9
x = 686
That means it will take Lily 686 dark power crystals to raise 6,174. That's a lot of dark power!
Hope this helps!
Answer:

Step-by-step explanation:
Answer: Option B is the cheaper deal (the 12 batteries for $14.76)
===========================================================
Explanation:
For the first deal we can say
3 batteries = 4.80 dollars
3/3 batteries = 4.80/3 dollars .... divide both sides by 3
1 battery = 1.60 dollars
The unit price for the first deal is $1.60 per battery.
----------------------------------
For the second deal we could say
12 batteries = 14.76 dollars
12/12 batteries = 14.76/12 dollars .... divide both sides by 12
1 battery = 1.23 dollars
The unit price for the first deal is $1.23 per battery.
This is the cheaper deal.
----------------------------------
So in short, you're dividing the total cost over the number of items to get the unit price.
