Answer: Table C
Explanation: The X values match up with those on the graph!
Answer:
B) 57.4+x=67
Step-by-step explanation:
We take the amount in the piggy bank. Then we take the amount spent and add it to the amount she has left. These two amounts should be equal
piggy bank = spent + left
67 = x + 57.40
Answer:

Step-by-step explanation:
log20 = 1.301 (when you see only "log" with no base, it is taken as a base 10)
This basically means:
(This is the log in exponential form)
Since we don't know what
is equal to, we will say
= x
So to solve for
= x, you do the same thing. (convert to exponential form)

Now you will notice that both of these equations are equal to 20.
Since 20 = 20,
we can say
= 
Another way of saying 100, is
(make the bases the same)
Now we get
(we get 2x because an exponent to the power of an exponent (
) is the same as 2 * x)
Because you have the same base, you can just ignore the 10s and focus on the exponents. So you get:
2x = 1.301
x = 0.6505
