Answer:
Choice A
Step-by-step explanation:
A restriction of just a point is a hole, which means it is in the denominator
To determine this, we look at the denominators,
B and C do not have denominators,
Square roots cannot be negative, so they have larger restrictions
for D x+2 ≥0
x≥-2
Choice A is the only option that has a restriction that is a hole
x+2 ≠0
x≠-2
(Are you saying the king case is an additional 12% of $84? I think you should word the question a bit more clearly).
12% = 12/100 = 0.12 multiplied by $84 = $10.08 = $84 + $10.08 = $94.08
We have $94.08 so far (king case and camera price combined).
Tax is 6%, so 6/100 = 0.06 multiplied by $94.08 = $5.64
Add $5.64 to the $94.08 total we calculated.
$94.08 + $5.64 = $99.72 <=== this is our total cost plus tax.
So 8w=4c and 2c=3g. divide the first equation by 2 and you get 4w=2c. merge the two equation give you 4w=2c=3g, or 4w=3g. multiply 4 on both sides give you 16w=12g. So 16 widgets equal how 12 goof-ups?
If you would like to know the solution to the equation, you can calculate this using the following steps:
4/5n - 3/5 = 1/5n /*5n
4 - 3/5 * 5n = 1
4 - 3n = 1
4 - 1 = 3n
3 = 3n
n = 1
The correct result would be n = 1.
