Kathy counts 9 goats and sheep at the petting zoo. Her brother counts 4 goats. Write 2 ways you can find how many sheep there ar

Method 1 (without using an equation):

Total number of goats and sheep is 9. Since her brother counts 4 goats, the remaining animals must be sheep.

Calculating 9 minus 4 gives 5 sheep.

Method 2 (using an equation):

Let x equal the number of sheep present. Since there are 4 goats, total animals are x + 4, which equals 9.

Set up the equation: x + 4 = 9

Subtract 4 from both sides to find x:

x = 9 - 4

x = 5

Alternate Method 3 (using an equation):

Assuming the total animals are 9, then the amount of goats is 9 - x (where x is sheep).

Since her brother counts 4 goats,

9 - x = 4

which rearranges to

x = 9 - 4

x = 5

Therefore, there are 5 sheep.

One way: 5B + B = 20

Another way: 6B = 20

Solving gives B = 20 / 6 = 10/3 hours.

Then, A = 5 × (10/3 + 2) = 80/3 hours.

Brian traveled 10/3 hours, Annie traveled 80/3 hours.
