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.

Answer:
51m
Step-by-step explanation:
For this equation, you want to use pythagoras' theorem (or pythagorean theorem) to work out the hypotenuse (diagonal line)
The formula for this is a²+b²=c², where c is the hypotenuse.
We can sub in the 2 sides for a and b, turning the equation into 24²+45²=c².
Working out the squares gives 576+2025=c², which can be solved to c²=2601.
To get c, we must square root both sides, which results in c=51m.
