Width=19
Length=17
72-4=68/2=34/2= 17 length
72-4=68+4=38/2=19 width
Answer:
Keegan is 16 and Jamie is 13.
Step by Step Explanation:
So if we were to take the number 39 and divide it by 2, we would get 19.5. Since Jaime is 3 years younger, we would subtract 3 from one of the 19's. Then we would add 1.5 to both of the numbers since that 3 we subtracted has to go somewhere in that 39, and we come up with the numbers 21 and 18. Since it is asking how old they are NOW and not in the future, we subtract 5 from both numbers to account for the 5 years, and we end up with the years 16 and 13.
Math:
39÷2 = 19.5
19.5 19.5
-3

Answer:
a= -infinity to 3
Step-by-step explanation:
Given
Required
Determine the value of a such that the inequality has no solution
Considering the first inequality (<em>Solve for x)</em>:
Collect Like Terms
Divide both sides by 10
Reorder
This means that the least value of x is 2;
Substitute 
in the second equation
Collect Like Terms
Reorder
This means that the least value of a is 4
Hence;
<em>The values of a for which the system has no solution is -infinity to 3</em>
(b) If the temperature is 23 in degrees Celsius, what is the temperature in kelvins? Show your work.
C = K − 273.15
23 = K - 273.15
296.15 Kelvin
(c) Which is greater, 300 kelvins or 25 degrees Celsius? Show your work.
To compare, we need to convert both to the same units. We do as follows:
300 Kelvin
25+273.15 = 298.15 K
Therefore, 300 Kelvin is larger.
