Answer:
19 and 16
Step-by-step explanation:
Let x and y be the two numbers
x+y = 35
x-y =3
Add the two equations together
x+y = 35
x-y =3
---------------
2x = 38
Divide by 2
2x/2 = 38/2
x = 19
Solve for y
x-y = 3
19-y = 3
Subtract 19 from each side
19-19 -y = 3-19
-y = -16
y =16
48:9
So, their's 48 kittens in 9 puppies.
48:9
96:18

Answer:
18 cm and 42 cm
Step-by-step explanation:
a = wl
7w = 3l, then l = 7/3w
756 = w(7/3w)
756 = 7/3w²
w² = 324
w = 18
l = 42
The answer would be be between 1 and 0.7
