Answer:
The answer is X = 18
Step-by-step explanation:
2x/3 - 7 = 5
Multiply both sides if the equation by 3 : 2x - 21 = 15
Move the constant to the right hand side and change its sign : 2x = 15 + 21
Calculate 2x = 15 + 21
2x = 36
Divide both sides of the eqaution by 2 : 2x = 36
x = 18
Answer X = 18
Answer:
Four more than three times a number is greater than twenty-two.What is the number?
The number is greater than 6.
Step-by-step explanation:
Given:
Four more than three times a number is twenty-two.
Let the number be 'x'.
Three times of 'x' = '3x'
Four more means further four is added.
So,
The number is 
According to the question.
⇒ 
⇒ 
...Subtracting 4 on both sides
⇒ 
⇒ 
...Dividing 6 on both sides
Now if it says that it is greater than 22 then we will use 
sign.
So the number is greater than 6 'x' > 6.
You would start by setting up the equation:
7x=125 where x is equal to the number of books sold
x=17.9
Since you cannot sell .9 of a book, this must be rounded up to 18.
Therefore, Amy must sell 18 books.
We write the expression:
((2 ^ (1/2)) * (2 ^ (3/4))) ^ 2
We use for this case the properties of lso exponents:
((2 ^ (1/2)) * (2 ^ (3/4))) ^ 2
((2 ^ (2/2)) * (2 ^ (6/4)))
((2 ^ (1)) * (2 ^ (3/2)))
((2 ^ (1 + 3/2))
((2 ^ (5/2))
answer:
((2 ^ (5/2))
option 2
