It's 12 because if you divide 6 by 0.5 you should get 12, so basically use the opposite operation.
Hope that helps!
14=2x +6
14-6=2x+<u>6-6</u>
8=2x

The fraction of the original mass that was lost in the second month is 1/12.
<h3>What is the fraction?</h3>
A fraction is a non-integer that is made up of numerators and denominators. An example of a fraction is 1/10.
Weight lost in the first month = 1/6 x 120 = 20kg
Weight lost in the second month = 1/10 x (120 - 20)
= 1/10 x 100 = 10kg
Fraction of the original mass that was lost in the second month : weight lost in the second month / total mass
10 kg / 120 = 1/12

Answer:
Monthly Expense = $270.83
Step-by-step explanation:
The semi-annual premium is paid twice a year so,
Automobile insurance premium for whole year = 650*2
= $1300
Monthly premium will be paid 12 times a year so,
Health insurance premium for whole year = 125*12 = $1500
Annual premium is only paid once a year.
So adding all the premiums will give us the total premiums for whole year.
Total amount of premium for a year = $1300+$1500+$450
= $3250
The premium amount for whole year is $3250. To find the monthly expense, we will divide it by 12.
So monthly expense is:
= 3250/12
= $270.83 ..
Answer:
y=68.38172757
Step-by-step explanation:
Take the inverse cosine of both sides of the equation to extract
y from inside the cosine.
y=arccos(7/19)
y=68.38172757
The cosine function is positive in the first and fourth quadrants. To find the second solution, subtract the reference angle from
360 to find the solution in the fourth quadrant. y=360−68.38172757
y=68.38172757+360n,291.61827242+360n, for any integer n
