Hey there! I'm happy to help!
Let's call this number n. Here is the info we can write about it. Remember that to write as a percent as a decimal you divide by 100.
n-0.16n=159.6
We combine like terms.
0.84n=159.6
We divide both sides by 0.84
n=190
Have a wonderful day! :D
Answer:
c) -4/5
d) 4/5
Step-by-step explanation:
The given equation is 25x^2 -16 = 0
Adding 16 on both sides, we get
25x^2 = 16
Dividing both sides by 25, we get
x^2 = 16/25
Taking square root on both sides, we get
x = √(16/25)
x = ±4/5
Therefore, x = 4/5 and x = -4/5
Answers: C) and D)
Hope this will helpful to understand the concept.
Thank you.
As we can see that common difference is increasing to one more digit after every term
so it means
a21 = 231
104 wall because 38+38 is 76 and 76+28 is 104
