Answer:
the number if people in line when the booth opened.
Step-by-step explanation:
70-5x: the number goes down by 5 people per minute. So for example if it has been 10 minutes, 50 people would’ve been given their tickets.
The picture in the attached figure
we know that
In similar triangles. The ratio of the lengths of the sides CS and CB must be equal to the ratio of the lengths of sides CR and CA. CS / CB = CR / CA
which can also be written as,
CS / (CS + SB) = CR / (CR + RA)
CS*(CR+RA)=CR*(CS+RA)
CS=2x+1
SB=6x
CR=7.5
RA=18
(2x+1)*[7.5+18]=7.5*[2x+1+18]
(2x+1)*[25.5]=7.5*[2x+19]
(51x+25.5)=15x+142.5
51x-15x=142.5-25.5
36x=117
x=117/36
x=3.25
the answer is x=3.25
You need to understand the different kinds of categories in order to solve this problem.
There are:
types of crusts - 3
types of toppings - 5
You multiply these together (3 x 5)
Your answer should be 15
