Answer:
4a - 40 = 1
Step-by-step explanation:
4/5 a - 8 = 1/5
Multiply each side by 5 to clear the fractions
5(4/5 a - 8) = 1/5 *5
distribute
4a - 40 = 1
What is the question supposed to be?
Answer:
6 cells
Step-by-step explanation:
Cell A = 1 hour to complete cycle and produce 2 cells
Number of cycles completed on 6 hours = 6 cycles
Number of cell produced = 2 * number of completed cycles = 2 * 6 = 12 cells
Cell B = 2 hours to complete a cycle ; 2 cells produced per cycle
Number of cells produced after 6 hours :
Number of cycles in 6 hours = 6/2 = 3 cycles
Number of cells produced = 3 * 2 = 6 cells
Difference in cells produced : (12 - 6) = 6 cells
It is a linear equation (ie., no x²), so solution should be possible.
First, let's get rid of the brackets:
2/4 x - 1/4 + 1/5 x - 1/5 = 2
Next, lets change the denominator to 20, the least common multiple of 4 and 5:
10/20 x - 5/20 + 4/20 x - 4/20 = 40/20
Then simplify by taking the x terms together and the constant terms:
14/20 x = 49/20 (now multiply by 20 to remove the denominator)
14x =49 (now divide left and right by 14)
x = 49/14 (divide numerator and denominator by 7)
x = 7/2
Of course, there's any order in which you can perform these operations. They should all lead to the same answer.
