Hello,
let's say v the speed of transmission
v=20kB/4s=5 kB/s
Data downloaded =v*t=5kB/s*15s= 75 kB*s/s= 75 kB.
Answer: -3n-2.
Because for the first term, for example, plug in 1, you'll get -3(1)-2=-3-2=-5, which is the first one. Try it with all terms.
After combining like terms:
-0.7k + 1 = 7.8
Subtract the 1 from both sides:
-0.7k = 6.8
Divide by -0.7 from both sides:
k = -9.7142, simplified is -9.7
Checked Answer:
-0.7(-9.7) = 6.79, simplified is 6.8
The answer is 160
hope it will be help ( ´ ▽ ` )ノ
