Answer:
74 and 27
Step-by-step explanation:
let x and y be the numbers
x + y =101........eqn 1
x - y = 47.......eqn 2
solve simultaneously
from equation 2, make x the subject
x= 47 + y........eqn 3
put eqn 3 into eqn 1
(47+y) + y = 101
47 + 2y = 101
2y= 101 - 47
2y=54
y= 54/2
y= 27
put y=27 into eqn 3
x = 47 + 27
x = 74
Answer:
There is an inverse relationship between the total magnification and the diameter of the field of view – i.e., as magnifications increases the diameter of the field decreases in proportion, so the diameter of field of view at different magnification can be calculated mathematically, using the formula.

Answer:
6 2/3 cups needed
Step-by-step explanation:
So first I would find the unit rate for cookies and cups
1 cup = 9 cookies
So now divide becuase we want to find the amount of cookies
60/9= 6.666666666 or 6 2/3
Now normally it would just be left like that
