Answer:
x = -1
Step-by-step explanation:
x = x2 -5x = 3
-5x + 2x = -3x
x = 1
(-1)2 - 5(-1) = 3
-2 + 5 = 3
Answer: 20790
Step-by-step explanation:
6!+7!+8!=(n)(6!)
calculate the individual values first:
6!=720
7!=5040
8!=40320
plug them into the equation:
720+5040+40320=n720
solve for n
5760+40320=n720
46080=n720
divide both sides by 720 to isolate n
46080/720=n720/720
64=n
Answer:
2121.8
Step-by-step explanation:
The principal is 2000
Rate is 3%
Time is 2 years
Therefore the amount that will be present in the account after 2 years can be calculated as follows
= 2000 × (1+0.03)^2
= 2000 × 1.03^2
= 2000 × 1.0609
= 2121.8
the answer to your equation is
n=40
