A scholarship fund raised $7,000 in contributions. Part of the contributions were invested in bonds paying 6% interest, and the rest were invested in
bank certificates paying 8.5% interest. If the total annual income is $520,
create a system to model the scenario. Then find the amount invested in the
8.5% account.

Simplify the expression and find the missing terms. the simplest form of has in the numerator and in the denominator.

How do you solving the solution of each system using elimination?

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
