First set up birds is +3 than 2x the number of birds Rhonda saw
Rhonda's birds = r
Current set of birds = c
c = 2r + 3
Current birds are equal to three more than double the amount of birds rhonda saw
The last one is the answer
<em>Greetings from Brasil...</em>
According to the statement, one figure is scaled in relation to another, so we can apply similarity to polygons.....
So
BIG/small = BIG/small
or
small/BIG = small/BIG
12.5/10 = X/16
OR
10/12.5 = 16/X
12.5/10 = X/16
10X = 12.5 · 16
X = 200/10
<h3>X = 20</h3>
The only equation that matches the first point (x, y) = (2, 2) is that of ...
c) y = 3/2x -1
Joe completes an average of (10 ft)/(5 h) = 2 ft/hour. Bill completes an average of (10 ft)/(4 h) = 2.5 ft/hour. Together, they complete 2+2.5 = 4.5 ft/hour. At that rate, it will take them
... (120 ft)/(4.5 ft/h) = 26 2/3 h
