Kids were playing baseball outside the house and broke 20% of the windows. if they broke 6 windows, how many windows did the house have? find the answer by showing two different methods.

windows * 20 percent = 6

windows * .2 = 6

divide each side by .2

windows = 6/ .2

window = 30 windows

6 windows         20

 =

total windows    100

cross products

6 * 100 = 20 * total windows

600 = 20 * total windows

divide each side by 20

600/20 = total windows

30 = total windows

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
