Step-by-step explanation:
First you want to find the unit rate so divide both numbers
so the answer is 3
Answer:
3.45
Step-by-step explanation:
first you use a calculator.
Answer:
Mean: 12.6
Median: 12
Mode: 9, 10, 12, 15, 17
Step-by-step explanation:
Mean: To find the mean you have to add up all your terms and divide your result by the number of terms you have. ((12+9+17+15+10) / 5)
Median: To find the median you have to organize your terms from least to greatest and then find your center term. (12)
Mode: Normally to find your mode would be to organize your terms from least to greatest and see which of your terms occurs the most. In this case all terms occur only once, making all your terms the mode.

Define x :
-----------------------------------------------
Let the width be x
Width = x
Length = 4x + 7
-----------------------------------------------
Formula :
-----------------------------------------------
Perimeter = 2 (Length + Width)
Perimeter = 74
2(4x + 7 + x) = 74 // sub length and width into the equation
2(5x + 7) = 74 // combine like terms
10x + 14 = 74 // Apply distributive property
10x = 60 // Take away 14 from both sides
x = 6 // Divide by 10 on both sides
-----------------------------------------------
Find Length and Width :
-----------------------------------------------
Width = x = 6mm
Length = 4x + 7 = 4(6) + 7 = 31mm
----------------------------------------------------------------------------------------------
Answer: The length is 31mm and its width 6mm.
