Answer:
35 dogs
Step-by-step explanation:
We can simplify the ratio 49:28 by dividing by 7
The new ratio is 7:4 which is easier to work with.
It says there are 20 cats so we know that for every 4 cats there are 7 dogs
We simply multiply 20 by 7/4
20 x 7/4 = 35 so there are 35 dogs
N= C. 23
2n-4=42
add 4 to both sides
2n=46
divide both sides by 2
n=32
You would multiply a single digit from the second number by every number in the first and repeat the process while adding a zero at the end of the next number.
So you would do the equation 528*9 = 4,752 then for the next one your equation would look something like:
528
x002
-------
10,560
The zero at the end being added on. After you do this with all three numbers you get 158400, 10560, and 4752. Add them together and get 173712 and there is your answer: 173,712
