Answer:x = 8, y = 5
Step-by-step explanation:The sum of two numbers is 13. Two times the first number minus three times the second numberis 1. If you let x stand for the first number and y for the second number, the two numbers are: A. x = 8, y = 5
We already know that Emma is 12, and if Luke is twice her age, then that means we need to multiply 12 by 2, which equals 24. If Kendra is one half of Luke's age, which is 24, then we must divide 24 by 2, which equals 12.
In conclusion, Kendra is 12 years old.
Answer:
Average speed is 3 kilometers an hour
The equation used for this problem is
F = P(1+i)ⁿ
where
F is the future worth
P is the present worth
i is the effective interest rate
n is the number of years
Substituting the values,
F = <span>$8,000(1 + 0.03)</span>⁴
F = $9,004.07
Thus, after 4 years, Aaron will have $9,004.07.
