There are 22 animals in the barn. Some are geese and some are goats. There are 82 legs in all. How many of each animal are there
Free_Kalibri [48]

Let the number of geese be x.

Then number of goats is 22-x.

A goose has 2 legs, and a goat has 4.

There are a total of 82 legs.

So,

2x + 4(22-x) = 82

2x + 88 - 4x = 82

-2x = -6

x = 3

There are 3 geese and (22-3=) 19 goats.

Express in exponential form. log2(x)=3
igomit [66]
The relationship between logarithms and exponentials is that they are inverses of each other. That is, they are reflected about the line y = x.
In order to rewrite logarithms, we need to understand the basic fundamentals of them:
log_ab = y

This is essentially saying: "If we raise a to the y-th power, we get the answer to b".
Using this, we can say:
log_2x = 3 \rightarrow 2^{3} = x
