Answer:
26.7
Step-by-step explanation:
This is the answer because 26.7/20 = (16+26.7)/32
When two triangles are similar, it means their sides are also proportional. The reason why it is not ten is because you need to add 10 to 16 to the large triangle as well, which no longer makes it proportional.
To solve, you create a formula.
(16+x)/32=x/20
Multiply both sides by 32 to get rid of the 32 in the left side.
16+x=32x/20
Multiply both sides by 20 to get rid of the 20 right side.
320+20x=32x
-20x on both sides to get all the variables on one side and all the nukbers on the other.
320=12x
Divide both sides by 12 to get x by itself
x=26.66667
Answer:
a = 
Step-by-step explanation:
Given
ga + q = r ( subtract q from both sides )
ga = r - q ( isolate a by dividing both sides by g )
a = 
Answer:

Step-by-step explanation:
So I'm assuming when you typed "log yhat=.4785 + 1.468x", you meant to write:
. And generally a logarithm can be written in the form
which can then be rewritten as
, but since the log has no base, it's assumed to be 10. So in this case you have the equation:
, which can then be written in exponential form as:
