<h3>
answer:</h3>
x = 5
y = -4
<h3>
steps:</h3>
4x + y = 16
multiply 2nd equation by 2
4x + 6y = -4
subtract equations
0 -5y = 20
-5y = 20
y = 20 ÷ -5
y = -4
substitute y = -4 to find the value of x
4x + (-4) = 16
4x - 4 = 16
4x = 20
x = 5

1mile because 1/5 X 5 = 1/1 or 1 :)
Let's name the bag of apples "x"
they have 3 bags of apples: 3x
then they need to divide it among 5 people: so each person gets 3/5
The person would have to leave the money in the bank for 7.8 years for it to reach 13,500 dollars.
Step-by-step explanation:
Step 1; First we must calculate how much interest is generated for a single year. The annual interest rate is 4.5% i.e. 4.5% of 10,000 dollars which equals 0.045 × 10,000 = 450 dollars a year. As the years pass, more and more will be put into the account due to interest.
Step 2; For there to be 13,500 dollars in the bank account we need to calculate how much money is added due to interest.
The money needed to be added through interest = 13,500 - 10,000 = 3,500 dollars.
So we need to determine how long it will take for the bank to add 3,500 dollars by adding 450 dollars a year.
The number of years to reach 13,500 dollars =
= 7.777 years. By rounding this value to the nearest tenth, we get 7.8 years.
