Answer 2

It looks like you've provided a series of equations with variables and ratios. It's not entirely clear what you're asking, but I'll do my best to help you understand and solve these equations. Please let me know if you need specific solutions or further clarification for any of them.

1. 29r = 5 This equation is quite simple. To solve for r, divide both sides by 29: r = 5/29

2. 1.6r + 9 = 9y This equation appears to relate r and y. To solve for y, isolate it on one side of the equation: 1.6r = 9y - 9 Divide both sides by 1.6: y = (9y - 9)/1.6

3. 0.84r + 0.6y = 3 This equation relates r and y. To solve for y, isolate it on one side of the equation: 0.6y = 3 - 0.84r Divide both sides by 0.6: y = (3 - 0.84r)/0.6

4. 7.5 + 6.9y = 8r This equation relates r and y. To solve for r, isolate it on one side of the equation: 8r = 7.5 + 6.9y Divide both sides by 8: r = (7.5 + 6.9y)/8

If you have specific values for r or y that you'd like to substitute into these equations, please provide those values, and I can help you calculate the corresponding variables.
