Answer:
hi sorry i need points im in the neggative somehow
Step-by-step explanation:
I must assume that you meant the following:
10(Q-3R)
P = ----------------
R
Multiplying both sides by R, we get PR = 10R(Q-3R), or PR = 10RQ - 30R^2.
Rearranging these terms so that powers of R are in descending order:
30R^2 - 10RQ + PR = 0
Factoring out R, we get
R(30R - 10Q + P) = 0. This has two solutions:
R = 0, and 10Q - P
30R = 10Q - P, so that R = --------------
30
Answer: 60/7
Step-by-step explanation:
- Multiply 8 and 7, which is 56.
- Add 56 and 4, which is 60. This means that the improper fraction is 60/7.
