Check the picture below.
you really have two rectangles, a 6x10 and a 6x5, and surely you know what those areas are, so sum them up, and that's the area of the polygon.
Answer: plants are same height in 30 days; Plant A is tallest in 6 weeks
Step-by-step explanation:
x = number of days
4 + (2/3)x = 9 + (1/2)x
(2/3)x - (1/2)x = 9 - 4
(1/6)x = 5
x = 30, number of days for Plant A and Plant B to be same height.
6 wks = 42 days
Plant A in 42 days: 4 + (2/3)(42) = 32 inches
Plant B in 42 days: 9 + (1/2)(42) = 30 inches
The unit of time that will make the statement true is "day"
<h3>What unit of time will make the statement true?</h3>
The conversion equation is given as:
Seconds + Seconds/? * day = seconds
Represent the blank with a variable (x)
So, we have:
Seconds + Seconds/x * day = seconds
Subtract "seconds" from both sides of the equation
So, we have:
Seconds/x * day = seconds
Divide both sides of the equation by "seconds"
So, we have:
1/x * day = 1
Multiply both sides by x
x= day
Hence, the unit of time that will make the statement true is "day"

Answer:
The price of each CD before tax is $15.70
Step-by-step explanation:
Given that:
Number of CDs bought by Reuben = 5
Cost of five CDs = $81.50
Sales tax on each CD = $0.60
Sales tax on 5 CDs = 0.60*5 = $3.00
Price of CDs without tax = 81.50 - 3.00 = $78.50
Price of each CD = 
Price of each CD = 
Price of each CD = $15.70
Hence,
The price of each CD before sales tax is $15.70
