Answer: 46 or 46=4
Step-by-step explanation:
Do what's in the Parenthesis first so 7+2=10 which now give you the equation
[10x 5-4]=2+2
Now we Multiply so we do 10x5 which is 50 so that now gives us the equation[50-4]=2+2
Now we add the 2+2 which is 4 giving us the equation [50-4]=4
Now we subtract 50-4 giving 46
46=4
The answer is 6 (x + 5) (x - 5)
3 cats can catch 3 rats in 3 minutes ==> 1 rat per minute.
It takes 3 cats to catch 1 rat per minute.
100 rats in 100 minutes ==> 1 rat per minute
The same <u>3 cats</u> can do it, if they don't wear out and take naps.
