<span>seventy two hundredths</span> = 0.72.
Decrease = Subtraction.
Two Tenths = 0.2
So:
0.72 - 0.2
0.72 - 0.2 = 0.52
So, This Expression Is Equal To 0.52
Rabbits Cows Chickens
6 : 3 : 2
rabbits - chickens = 8
6 parts -2 parts = 8
4 parts =8
1 part =8/4
1 part =2
cows have 3 parts so
3 parts =cows
3 x 2 (1 part) = cows
cows = 6
Answer:
x = 2.56, y = -2.63
Step-by-step explanation:
I first multiplied the second equation by two, getting
4x-6y = 26
I then subtracted the equations
4x+2y = 5
- 4x-6y = 26
--------------------
8y = -21
y = -2.63
with y solved, I plugged it into the second equation to get x:
2x-3(-2.63) = 13
2x+ 7.89 = 13
2x = 5.11
x = 2.56
I hope this helped! ;D
