Answer:
C. solution:
3(3c-2) = 5(2c-1)
or, 9c-6 = 10c-5
or, -6+5 =<em> </em>10c-9c
or, -1 = 1c
Hence, c = -1.
D. solution:
5(5-2a) = 4(6-a)
or, 25-10a = 24 - 4a
or, 25-24 = -4a+10a
or, 1 = 6a
or, 1/6 = a
Hence, a = 1/6.

Answer:
The updated IQR is 14.54.
Step-by-step explanation:
The interquartile range is given by the difference between the 75th percentile(value that is greater than 75% of the measures) and the 25th percentile.
This means that each piece of wood is actually 5 inches shorter than the value recorded by the employee.
This means that the length of each wood is less than 5. However, the difference between the 75th percentile and the 25th percentile will stay the same, since both were subtracted by 5.
The updated IQR is 14.54.
Answer:
Step-by-step explanation:
Move x / 4 to left hand side and change its sign
Similarly, move 2 to right hand side and change it's sign
Take the L.C.M of 3 and 4
L.C.M of 3 and 4 = 12
Subtract 2 from 3
Do cross multiplication
--------------------------------------------------------------------
Distribute 3 through the parentheses
Move x to left hand side and change it's sign
Similarly, move 12 to right hand side and change it's sign
Collect like terms
Subtract 12 from 33
Divide both sides by 7
Calculate
