Answer:
Step-by-step explanation:
We are asked to solve the given equation: 
.
To solve this equation we will combine like terms by moving all the terms containing x to the left hand side of equation and terms without x to right hand side of equation.
Let us add 8x to both sides of our equation.
Let us subtract 8 from both sides of our equation.
Upon dividing both sides of our equation by 6 we will get,
Therefore, the value of x equals 1 will satisfy our given equation.
In other words this means every number is less than 8
Therefore the answer would be:
8
It must be an odd number because 3^7 is also shown as:
3x3x3x3x3x3x3
Which equals:2,187
2,187 is an odd number because the last number is a 7 which is odd.
Answer:
3. 3 and 4
4. 5 and 6
5. x=-3
Step-by-step explanation:
3. 
is between 3 and 4 because 3 is equal to 
and 4 is equal to 
. Since 11 is in between 9 and 16 this is the answer.
4. Same thing, except since 5 is 
and 6 is 
, and 34 is between 25 and 36
5. The equation is -31=4x-19, and we need to isolate x
First, add 19 to both sides
And next divide both sides by 4 to get
As both are adding same number of comic books each months, they will not have same number of books. Adrian will have 4 more comic books.
Step-by-step explanation:
Given,
Adrian starts with 12 comic books and add 4 each month.
Let,
m be the number of books.
A(m) = 4m+12
Rory starts with 8 comic books and add 4 comic books each month.
R(m) = 4m+8
As both are adding same number of comic books each months, they will not have same number of books. Adrian will have 4 more comic books.
