Answer:
x = ± 4/5
Step-by-step explanation:
25 x^2 = 16
Divide each side by 25
25 x^2 /25 = 16 /25
x^2 = 16 /25
Take the square root of each side
sqrt(x^2) = ±sqrt(16/25)
We know that sqrt(a/b) = sqrt(a)/ sqrt(b)
x = ±sqrt(16) / sqrt(25)
x = ± 4/5
3/70=x/100
(3/70)*100=x
300/70=x
x=30/7=4.2857 roughly

Answer:
48
Step-by-step explanation:
We are asked that the value of (4n + 7) will be an integer > 1 and < 200, for how many integer values of n.
So, equating (4n + 7) with 200 we can get the value.
4n + 7 = 200
⇒ 4n = 193
⇒ n = 48.25
Hence, the value of n will be the largest integer less than 48.25.
Therefore, the number of integer values of n will be 48. (Answer)
