Similarity means that the two rectangles have the same shape and proportions, but not the same size.
Set up a proportion for the two rectangles to find the missing width of rectangle B:
The numerator represents the length, and the denominator represents the width of the rectangles.
Cross multiply the fractions:
Divide both sides by 10 to get x by itself.
The width of the second rectangle is 15 centimeters.
The area of a rectangle is given by the following:
width * length
Multiply the width by the length to find the area of this rectangle.
The area of rectangle B is
450 square centimeters.
Equation 1:
y = -9x + b
-7 = -9(-2)+ b
-7 = 18+b
b = 11
y = -9x + 11
Equation 2:
y = -0.4x + 8

Answer:
10/3 pizza
Step-by-step explanation:
step one:
This problem is focused on ratios and fractions
from the problem statement, Martin has 5/6 pizza
Liam has 4 times more of what Martin have
