Mr mannings class observed 4 more birds than mr Gallagher
Answer:
16
Step-by-step explanation:
64 = 4x
64/4 = 4x/4
16 = x
Lets say a photo = x
7x + 4x = 33
11x = 33
x = 3
7x = 7*3 = 21
4x = 4*3 = 12
The 2 groups are 12:21
Answer:
60 days
Step-by-step explanation:
To find when the two actions will happen together again, we just need to find the least common multiple of 12 and 30.
To do this, first we factor them in prime numbers:
12 = 2 * 2 * 3
30 = 2 * 3 * 5
Now we choose one of them and add the prime factors that the number chosen does not have from the other.
If we choose 30, we should add a number 2, so 2 * 30 = 60
If we choose 12, we should add a number 5, so 12 * 5 = 60
So after 60 days Dexter will mow his lawn and wash the windows on the same day.
