Answer:
Given the equation: 
Distributive property of multiplication states that when a number is multiplied by the sum of the two numbers, the first number can be distributed to both of those numbers and multiplied by each of them separately i.e,
Now, using distributive property to LHS and RHS, we get
Combine like terms on RHS;
or
Subtract 3 from both sides of an equation;
2x+3-3 =4x+3-3
Simplify:
2x = 4x
or
2x = 0
⇒ x =0
Therefore, the value of x in the given equation
is 0.
Answer:
7.4 x 10 to the 9th power
Step-by-step explanation:
At the end of numbers, there is a decimal point. when writing in function notation, you bring the point to the left or to the right depending on if it is a negative or a positive number
in this problem, you are dealing with a positive number, so bring the decimal point to the left. count how many numbers it takes to get in between, in this number, 7 and 4. it takes 9 spaces to the left. now the decimal point has been moved, your number goes from 7,400,000,000 to 7.4 x 10 to the 9th power(7.4 x 10^9)
12/30 = 2/5
12/30 = 0.4
Answer: 2/5 or 0.4
