We set up the equation 580/4 = 725/x. Since we know these are proportional, we can cross-multiply and solve to get x = 5.
Answer:
The multiplicative inverse of 1/2 is 2.
Answer:
The perimeter is 41
Step-by-step explanation:
The perimeter of a shape is just the sum of all its sides added up. In this case, that would mean the perimeter is:
- 12 + 9 + 9 + 4.6 + 6.4 = P
- 30 + 11 = P
- 41 = P
