Answer:
x = 15.8
Step-by-step explanation:
let the number be x
according to the question equation is
x*5 - 2 = 77
5x - 2 = 17
5x = 77 + 2
5x = 79
x = 79/5
x = 15.8
Answer:
<h3>C. t = x + x - 6</h3>
Step-by-step explanation:
Let the time use by other one technician be x
if the other technician takes 6 minutes less than the first technician, then the time taken by the other technician will (x - 6)
The total amount of time t it would take to run the tests if the technicians work together will be expressed by taking the sum of the time taken by the two technician as shown.
First technician = x
Second technician = x-6
Sum of the time taken
t = x+ (x-6)
Hence option C is correct
