Hey!
Lets take the square root of all these answer choices.
√63 ≈ 7.9
√99 ≈ 9.4
√83 ≈ 9.1
√10 ≈ 3.2
So if we look at all the answer choices square root, the answer that is the closest to 9 is √83.
Therefore, your answer will be C. square root of 83.
Hope this helps! :)
(x+3)-3x/2= (x-2)/4
cross multiply
4(x+3) -3x= 2(x-2)
4x+12-3x=2x-4
4x-3x-2x=-4-12
-x= -16
x=16

103.5% would be £6210
Answer:
AP: 10, 0, -10, -20...
a = 10, d = -10
nth term of the AP = a + (n-1)d
= 10+ (n-1)-10
= 10 - 10n + 10
= 20 - 10n
a10 = 20-10(10)
= 20 - 100
= -80
Hope this helps!
