Answer:
x = 4
Step-by-step explanation:
Since the terms are in an arithmetic progression then there is a common difference between consecutive terms, that is
2x - 1 - (x + 1) = x + 5 - (2x - 1) ← distribute parenthesis on both sides
2x - 1 - x - 1 = x + 5 - 2x + 1, that is
x - 2 = - x + 6 ( add x to both sides )
2x - 2 = 6 ( add 2 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
The 3 terms are 5, 7, 9
Answer:
The additive inverse of 7 is −7, because 7 + (−7) = 0; The additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0.
I hope I'm right and good luck! :)
Answer:
d) 87.92
Step-by-step explanation:
V = A(base)* height= πr² * h= 3.14*2²*7=87.92
Answer:
7 hours
Step-by-step explanation:
Since, the final amount of caffeine formula would be,
Where,
P = Initial value,
r = rate per period,
t = number of periods,
Here, r = 10% = 0.10, t = h, A = 
Taking log both sides,
Hence, after 7 hours the amount of caffeine in a body to reduce by half.
