Hi!
So, x is going to be the price of one apple. We need to solve for x, so let's start with getting an equation up and running.
<em>3x + 0.84 = 5x
Now, we're going to subtract three from both sides.
3x - 3x + 0.84 = 5x - 3x
Now, we're going to divide 2 from both sides!
0.84 / 2 = 2x / 2
And our final answer is... 0.42 for each apple! =)

A) 31%
B) 31%
For the first problem, we know that 25 out of 80 tokens are black. To find the percentage all we have to do is divide 25 by 80, which equal 0.31. To convert this to percentage form, you move the decimal two places to the right, giving you 31%.
And for the second problem you do the same thing. Divide 5 by 16, giving you 0.31. Convert that into percentage, also giving you the percent of 31%.
Answer:
Step-by-step explanation:
Given
See attachment for sample space
Required
From the attached sample space, we have:
---- total outcomes
--- outcomes with 1 Y and 1 P = 2 i.e. (P,Y) and (Y,P)
So, the required probability is:

The dimensions of the scale drawing is length = 168 inches and width = 126 inches
<h3>How useful is a scale drawing?</h3>
Scale drawing helps to represent surfaces on earth in a paper by either enlarging its dimension, reducing its dimension by a constant factor called the scale factor.
The conversion or scale factor is 21 inches = 4 meters
If 21 inches = 4 meters,
then 1 meter = 21/4 inches
32 meters inches = 32 x 21/4 = 168 inches
24 meters = 24 x 21/4 = 126 inches.
In conclusion, length of the scale drawing is 168 inches and width of the scale drawing iss 126 inches

I am assuming this is a triangle.....P = a + b + c
P = 2a - 3 + 2a + 3a + 1....combine like terms
P = 7a - 2 <==
