Step-by-step explanation:
Sorry for not giving you the calculation here -
5/12 and 2/9 have denominators divisible by only 3 right? Well The common denominator that can then change is 3 because that's the only number they have in common (except 1)
If you're looking for the number of dogs (I'm assuming, you didn't specify), all you'd have to do is divide the number by two, then round down to find the number of dogs, then check your answer by adding that number and that number plus 5.
For example, yours would look like 125/6=62.5, and rounding down to 60.
Then check your answer by adding 60 and 65, the number of cats. 60+65=125.
There are 60 dogs inside the kennel.
Answer:
2x + 11 = 25
x = 7
Step-by-step explanation:
Let the number be x.
Double of x and add 11 equals 25.
2x + 11 = 25
Solve the equation.
2x + 11 = 25
Subtract 11 on both sides.
2x = 25 - 11
2x = 14
Divide 2 on both sides.
x = 14/2
x = 7
