Step-by-step explanation:
1
x - 4 = 20 ( multiply through by 3 to clear the fraction )
2x - 12 = 60 ( add 12 to both sides )
2x = 72 ( divide both sides by 2 )
x = 36
2
4 = 
( multiply both sides by 2 to clear the fraction )
8 = - 1 + x ( add 1 to both sides )
9 = x
3
12(x + 9) = - 108 ( divide both sides by 12 )
x + 9 = - 9 ( subtract 9 from both sides )
x = - 18
4
5x + 14 = - 7 ( subtract 14 from both sides )
5x = - 21 ( divide both sides by 5 )
x = - 
= - 4.2
First step is breaking down the word problem.
I think of a number.
U don’t know the number so called it x
The number add 3.
X + 3
Then it says multiply the outcome by 7
You are not sure what what the outcome could be so you put it in brackets
(X+3) times it by 7
(X+3) 7
The solution is 24.5
Solution means equal
(X+3) 7 = 24.5
Now you have the equation
To solve for x
By the BOMDAS method
You times 7 by what is inside the brackets
7x + 21 = 24.5
Now transpose
7x = 24.5 - 21
7x = 3.5
Divide both sides by 7
7x/7 = 3.5/7
Which cancel out 7 and leave x
So the original number is
Or u could say x = 0.5
C) Just substitute and check! :)
Answer:
4/a
Step-by-step explanation:
This is a poor definition because it is not descriptive. If you would have said, "Elephants are an animal that have gigantic feet and gigantic bodies. Elephants also have a trunk that they use to drink water. Along with the trunk elephants also have a mouth." Yes elephant are a gigantic animal, but you have to have reasoning something to back it up or just make it more unique.
