You would do
3(1p) =3p-n+4
and then add a 1 to the n
3p-1n+4
add 1n+4
3p-5n
hope this helps! tysm
I choose A. 0, because the angles are complementary
Solve for n.
0.2(n - 6) = 2.8
Distribute
0.2*n - 0.2*6 = 2.8
0.2n - 1.2 = 2.8
Now inverse operation should be applied
0.2n - 1.2 = 2.8
+ 1.2 +1.2
2.8 + 1.2 = 4
0.2n = 4
0.2n/0.2 = 4/0.2
n = 20
Answer: 20
By the segment addition postulate,
AB = AC+CB
since C is somewhere between A and B
We know AC is 0.618 and AB = 1
CB = x for now
AB = AC+CB
1 = 0.618+x
1-0.618 = 0.618+x-0.618 ... subtract 0.618 from both sides
0.382 = x
x = 0.382
So CB is 0.382 units long
To find the ratio of AC to CB, divide the values
AC/CB = 0.618/0.382 = 1.618 (approximate to 3 decimal places)
Answer: Choice B) 1.618
Answer:
Step-by-step explanation:
Total number of tickets sold = 3388
Total number of coach tickets = 3069
Total number of first-class tickets = Total number of tickets sold - Total number of coach tickets
= 3388 - 3069
= 319
Ratio of the number of first-class tickets to the total number of tickets = 319:3388
