You solve an expression for a variable if that variable sits alone on one side of the equation, and everything else is on the other side.
So, our goal is to leave 
alone on the right hand side, and move everything else to the left.
So, we start with
We multiply both sides by 3:
We divide both sides by 
To compute the required height, simply plug in the values:
Answer: Answer is b
Step-by-step explanation: The -2 represents the 0's
Answer:
The right answer is the last option, 12,12.
Step-by-step explanation:
Alright! In order to solve this problem you need to know your keywords:
Sum = To add
Difference = Subtract
Product = To multiply
So! When it asks for the sum of 24 and 7 you add them:
24 + 7 = 31
The difference of 18 and 6:
18 - 6 = 12
The find the product of these two you simply multiply:
12 x 31 = 372!
Answer:
first you subtract 2 from both sides
-6x>18
then you divide
-6 by 18 which is -3 and since you divided with a decimal that flips your sign so your answer is X<-3
