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 are.

1 way (without equation)

Kathy counts in total 9 goats and sheep at the petting zoo. Her brother counts 4 goats. Then if you subtract the amount of goats from the total amount, then you obtain the amount of sheep.

9-4=5 is the number of sheep at the petting zoo.

2 way (with equation)

Let x be the number of sheep at the petting zoo. If brother counts 4 goats, then the total number of animals is x+4. Kathy counts in total 9 goats and sheep at the petting zoo, then x+4=9.

Solve this equation:

x+4-4=9-4,

x=5.

3 way (with equation)

Let x be the number of sheep at the petting zoo. If total number of animals is 9, then the amount of goats can be found as 9-x. Brother counts 4 goats, then

9-x=4,

9-4=x,

x=5.

5 sheep.

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
