Kerry and Luke biked a total of 18 miles in one weekend. Kerry biked 4 miles more than Luke. How far did each bike? Write a system of equations and solve.
let x - kerry y - luke x + y = 18 x = y +4 y + 4 + y = 18 2y = 14 y = 7 x = 11
$ 6,650 was invested at 3.5%, and $ 5,950 at 4.5%.
Since a student takes out two loans to help pay for college expenses, and the total amount of money borrowed is $ 12600, and both loans have interest that accrues annually, and the first loan has an interest rate of 3.5%, and the second loan has an interest rate of 4.5%, and after the first year, the interest from both loans total $ 500.5, to find the initial amount borrowed at 3.5% the following calculation must be performed:
- 6300 x 0.035 + 6300 x 0.045 = 504
- 6600 x 0.035 + 6000 x 0.045 = 501
- 6700 x 0.035 + 5900 x 0.045 = 500
- 6650 x 0.035 + 5950 x 0.045 = 500.5
Therefore, $ 6,650 was invested at 3.5%, and $ 5,950 at 4.5%.

Answer:
A rational number is a number that doesn't terminate or repeat
a non rational number is a number that terminates or repeats
so she basicelly got mixed up
Hope This Helps!!!
Answer:
Step-by-step explanation:
<u>Find the m∠B:</u>
- m∠B = (360° - 310°) + 50° = 100°
a)
<u>Find AC using law of cosines:</u>
- AC = √(8² + 13² - 28*13*cos 100°) = 16.4 km (rounded)
b)
<u>Find m∠A using law of sines:</u>
- 16.4/ sin 100 = 13 / sin A
- m∠A = arcsin (13 sin 100 deg / 16.4) = 51° (rounded)
<u>The bearing of C from A:</u>
c)
<u>Let the required distance is x:</u>
- x/ BC = sin 50°
- x = BC sin 50°
- x = 13 sin 50°
- x ≈ 10 km (rounded)
