Add all numbers together, then divide by the number of numbers there are. in this case divide by 6
Answer:
24
Step-by-step explanation:
(4y + 7) + (3y + 5) = 180. (angle on a straight line =180)
4y + 7 + 3y + 5 =180
4y + 3y + 7 + 5 = 180
7y + 12 = 180
7y = 180 - 12
7y = 168
y = 168/7
y = 24
Answer:

Step-by-step explanation:
Simple Interest
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
In this question:
We divide in two intervals, the first year and the second year. We have to know that the amount after the end of the first year is the principal at the start of the second year.
First year:
Amount of 2% interest, during 1 year.
So the interest earned is:
The total amount at the end of the first year is:
Second year:
We have that:
The interest earned is of:
The total amount is:
After two years, the investment is worth £8653.68 How much did Briony invest?
So
Brionny invested £8400.
Answer:
Distance between Kevin's home and movie theater is A) 6.32miles

Therefore,
miles
Thus,
Distance between Kevin's home and movie theater is A) 6.32miles
Answer:
