Answer:
D
Step-by-step explanation:
Because n is the number of days and 29.99 is the cost per day.
Also, $50 is the fee so you add that too.
Answer:
4x + 14
Step-by-step explanation:
So first you would 2 times 2x to get 4x and then 2 times seven to get 14. So you would get 4x plus 14.
Answer: No. To the contrary, "12,000,000" is the "standard form" of
"1.2 times 10 to the POSITIVE 7 power.
That is; "12,000,000 = 1.2 * 10⁷ " .

Answer:
(D) xy/(x + y)
Step-by-step explanation:
To find r in terms of x and y
Given,
- two resistors with resistances x and y are connected in parallel
- r is the combined resistance of these two resistors
- the reciprocal of r is equal to the sum of the reciprocals of x and y
Then,
1/r = 1/x + 1/y
1/r = (y + x)/xy
Find the reciprocal of both sides
r = xy/(x + y)
The right answer is option (D) xy/(x + y)
3(n+4)=1/2(6n+4)
2x3(n+4)=2x1/2(6n+4)
6(n+4)=1(6n+4)
6n+24=6n+4
24-4=6n-6n
20=O
