Answer:
x = -5.975
Step-by-step explanation:
distribute first by multiplying 2/5 by 'x' and then by 9/10 to get:
2/5x - 18/50 = -2 3/4
next, change -2 3/4 into an improper fraction to get:
2/5x - 18/50 = -11/4
now add 18/50 to -18/50 and to -11/4 using a common denominator of 100
2/5x = -275/100 + 36/100
2/5x = -239/100
multiply each side by 5/2 to isolate 'x':
x = -239/100 · 5/2
x = -1195/200
now simplify:
x = -5.975
Answer:
0.75 days (im a bit unsure but i tried my best, hope this helps :) )
Step-by-step explanation:
If it takes 8 technicians 36 hours to test 560 samples, find how many technicians can test 525 samples.
8: 560
x: 525
x= 7.5 (which is considered 7)
Then, find how long it takes to sample 525 samples, when 560 are done in 36 hours;
560: 36
525: x
x= 33.75 (which is considered 34 hours)
The last step is to check how long 15 technicians take to sample 525 samples when 8 can do the same number in 34 hours. this is inverse proportion so dont forget to flip one numerator and denominator
8; 34
15; x
it will become
15:34
8: x
x= 18 hours
Divide by 24 for days hence 0.75 days
Answer:

Step-by-step explanation:
Only reasonable answer, the other options are incorrect.
F = .7p
add the original discount of 50% to the additional of 20%. the total discount is 70%. multiply the 70% (.7 as a decimal) by the original price (p) to find the final price (f).
