I’m not exactly sure what the question is asking, but assuming that the equation is r=10b^2, then the answer would be r=40.
Answer:
67
Step-by-step explanation:
its not a 90!!! tilt your screen.
Here, we are required to determine the solution to the equation: 13.7y = 6.2y + 30?
The solution to the equation is y = 7.5
The solution is thus,
- 13.7y = 6.2y + 30
- 13.7y - 6.2y = 30
- 7.5y = 30
Therefore, y = 30/7.5 = 4
Therefore, y = 4 is the solution to the equation.
