Answer:
Step-by-step explanation:
so let’s say x is the length. Then the width will be 3x-4. You add them together and multiply by two. The perimeter is 72 so the equation equala 72.
Equation:
(x+3x-4)*2=72
(4x-4)*2=72
8x-8=72
8x=80
x=10
length:10
width:26
If you would like to know how many kilometers did Kelly jog that week, you can calculate this using the following steps:
Morgan: 51.2 kilometers
Kelly: Morgan - 6 kilometers = 51.2 - 6 = 45.2 kilometers
The correct result would be 45.2 kilometers.
A= adult
C= child
3A+C = 38.3
A+3C = 52
There is no logical way to find the value of each other than guess-and-check.
