1st equation should be multiplied with 3
6x+9y=24
-6x+4y=11
________
13y=35
y=35/13
2x+3y=8...1
put y=35/13 in 1
2x+3(35/13)=8
26x+105=104
26x=-1
x=-1/26
Answer: 0.52
Step-by-step explanation: 8 out of the 15 years were in the 90s. So 8/15 is 0.52
Answer:
Adam
Step-by-step explanation:
Speed is calculated with the formula distance over time.
Convert all measurements to the same unit: ft/s.
<u>Speed of Frank:</u>
d/t
=11/s
<u>Speed of Emily:</u>
d/t
=86/10
=8.6/s
<u>Speed of Adam: </u>
There are 5280 feet in a mile.
d/t
=5280/388
=13.6/s
<u>Speed of Noah:</u>
There are 60 seconds in a minute.
d/t
=600/60
=10/s
Adam runs the fastest because 13.6 > 11 > 10 > 8.6.
I believe the correct question is:
6.7*10^7 calc/sec?
So:
1/(6.7 x 10^7) = seconds per calculation
1/(6.7 x 10^7) = 100/(6.7 x 10^9) = 14.9 x 10^-9 seconds per
calculation = 14.9 ns
Which is approximately 15 ns
Answer:
15 ns
The one and the negative one
