Answer:
20 questions
Step-by-step explanation:
Well, 10% of 50 is 5, and 5 x 4 = 20. Another way is 50 x .4
X=7 because 7+6=13 and 3•13=39
Answer:
P = 100 centimeters (assuming you are asking for the perimeter)
Step-by-step explanation:
P = 2 (L + W) OR P = 2L + 2W where P equals the perimeter, L equals the length, and W equals the width.
Since the rectangle's length is 4 times its width and given we know the width is 10 centimeters, then the length is 40 centimeters. Now we can substitute these values in our formula, okay?
P = 2 (L + W)
P = 2 (40 + 10)
P = 80 + 20
P = 100 centimeters
I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.
