N * (n+1) = 3 (n + n+1) -3
n^2 +n = 3n + 3n + 3 - 3
n^2 -5n = 0
n * (n -5) = 0
n = 5
Check:
5 * 6 = 3 * (11) -3
Answer:
x = 21.4
Step-by-step explanation:
We need to use the law of sins
sin 42 sin x
--------- = ----------
22 12
12 sin 42 = 22 sin x
12 sin 42 /22 = sin x
Taking the inverse sin of each side
sin^-1(12/22 sin 42) = sin^-1(sin x)
21.40637223 =x
To the nearest tenth
x = 21.4
Answer:
3. x = 11.6
4. f = 2 g = 2
Step-by-step explanation:
3) (3x - 7) + (4x + 6) = 90 --> x = 11.6
4) 3f + 1 = 5f - 15 ---> f = 2
6g - 5 = 3f + 1
6g = 3(2) + 6 ---> g = 2
I believe it is 65 but I am not completely sure.
151 feet and 1 inch is equal to 151*12+1 inches, or 1813 inches.
