Answer:
x - 3 > 10
There were more than
13
board games in Anne's cabinet to start.
Step-by-step explanation:
The variable x represents how many board games were in Anne's cabinet to start. Since she has already picked out 3 board games to bring, the expression x–3 represents how many board games are still in the cabinet.
And, since Anne has more than 10 board games still in her cabinet, x–3 must be greater than 10.
This inequality shows the relationship.
x–3>10
Now, solve for x.
x–3
> 10
x–3+3
> 10+3 Add 3 to both sides
x
> 13 Simplify
So, there were more than 13 board games in Anne's cabinet to start.
The restrictions for the equation is that the denominator can not be zero. So the restrictions for x would be what values make the denominator zero.
7x^2 + 6x = 0
factor
x(7x + 6) = 0
multiply any number by 0 and you get 0. So either x = 0 or 7x+6 = 0
since there's a x in the numerator x/x = 1 so this will not be a restriction. Then the only restriction is:
7x+6 = 0
7x = -6
x = -6/7

Answer:
1/4
Step-by-step explanation:
Find common denominators. Note that what you multiply (or divide) from the denominator, you must also do the same to the numerator.
In this case, the common denominator would be 4. Multiply 2 to both the numerator & denominator of (-1/2):
(-1/2) * (2/2) = (-1 * 2)/(2 * 2) = -2/4
Subtract across:
3/4 - 2/4 = (3 - 2)/4 = 1/4
1/4 is your answer.
