Answer:
-6
Step-by-step explanation: 2(n+5)=-2
Remove the bracket(expanding):
2×n+2×5=-2
2n+10=-2
collect like terms:
2n=-2+(-10)
2n=-12
Dividing both side by the coefficient of n i.e 2
2n/2=-12/2
n=-6
Answer:
a) The rule is;
f = 5.75 + 2d
b) f = $33.75
Step-by-step explanation:
Here, we want to write a rule
The rule is that we have a standard download fee of 5.75 for the first download, and then a download fee of $2 per download for the rest
We have this as;
f = 5.75 + 2(d)
f = 2d + 5.75
Now for 15 downloads;
first download is $5.75, remaking 14 is at a rate of $2 per one
Thus, we have the fee value as;
f = 5.75 + 2(14)
f = 5.75 + 28 = $33.75
