On putting the value of given foot length in the linear equation, the shoe size of the man is 8.1.
A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0.

Answer:
The answer is 8.
Step-by-step explanation:
I had this in my math 1 test and got it wrong lol
you multiply by using the formula
x1*x2=y1*y2
B. 24 feet
C. 3 feet
D. 33 feet
**my answer: D. 33 feet
not too sure tho.. is that right?
The ball have traveled 33 m when it hits the ground for the fourth time.
The correct option is D .
Given, that a ball falls from 12feet.
Analyzing the fall of ball every time.
Fall 1:
Ball dropped from height = 12 m .
Ball returns to half the distance from which it is dropped .
Rebound distance covered by ball = 6 m .
Fall 2:
Ball dropped from height = 6 m .
Ball returns to half the distance from which it is dropped .
Rebound distance covered by ball = 3 m .
Fall 3:
Ball dropped from height = 3 m .
Ball returns to half the distance from which it is dropped .
Rebound distance covered by ball = 1.5 m .
Fall 4:
Ball dropped from height = 1.5 m .
Ball returns to half the distance from which it is dropped .
Rebound distance covered by ball = 0.75 m .
Total distance covered when ball hits the ground for fourth time:
12 + 6 + 6 + 3 + 3 + 1.5 + 1.5
= 33 meters.
The correct option is D .
