$ 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:
y = 8.5
Step-by-step explanation:
7y - 4 = 9y +13 - 4y
First arrange to combine like terms.
7y - 4 = 9y - 4y + 13
7y - 4 = 5y + 13 Subtract 5y from each side
7y - 5y - 4 = 5y - 5y + 13
7y - 5y - 4 = 13
2y - 4 = 13 Add 4 to each side
2y - 4 + 4 = 13 + 4
2y = 13 + 4
2y = 17 Divide each side by 2
2y/2 = 17/2
y = 17/2 or 8
or 8.5
Answer:
a. AA
b. no (sides are not proportional)
Step-by-step explanation:
a. Two angles are marked as congruent. The triangles are similar by the AA postulate.
__
b. The side ratios 6 : 8 : 11 and 15 : 20 : 33 are both in reduced form. They are clearly not identical, so sides are not proportional. The triangles are not similar.
