Solve for B.
R = x(A + B)
B = (R - A)/x
B = (A - Rx)/x
B = (R - Ax)/x **Weegy:** Answer is definitely c. B = (R - Ax)/x **User:** $5,000 is invested at 3% interest. How much money must be invested at 5% interest so that the total interest from the two investments is $275 after one year?

10(N + 14) = 9N
10(9N + 14) = N
10(N + 9N) = 14 **Weegy:** a.10(N + 14) = 9N **User:** Solve for B.
R = x(A + B)
B = (R - A)/x
B = (A - Rx)/x
B = (R - Ax)/x **Weegy:** Answer is definitely c. B = (R - Ax)/x **User:** Ralph is 3 times as old as Sara. In 6 years, Ralph will be only twice as old as Sara will be then. Find Ralph's age now.
If x represents Sarah's age now, which of the following expressions represents Ralph's age in six years?
2x
6x
2x+ 6
3x+ 6 **Weegy:** c. 2x+4 **User:** Find two consecutive integers whose sum is 67.

3(3x - 1) + 2(3 - x) = 0

9x - 3 + 6 - 2x = 0

7x + 3 = 0

x = - 3/7

9x - 3 + 6 - 2x = 0

7x + 3 = 0

x = - 3/7
