The first thing you do is distribute. So multiply -7 to n and 6 to get -7n-42=-91 add over -42 to -91 to get -7n=-133 then divide by 7 on both sides and you get n=19

-91=-7(n+6) step 1: distribute -7 to n and 6
-91=-7n+(-42) step 2: add 42 to both sides
-91+42=-7n+(-42)+42
-49=-7n step 3: divide both sides by -7
-49/-7=-7n/-7
7=n

Vladimir [108]
F=5.77X10^9(1.032^(y-1985)), we want to know when this is:

2.2X10^12=5.77X10^9(1.032^(y-1985))

381.2825=1.032^(y-1985)

ln(3,812825)=(y-1985)ln(1.032)

ln(3.812825)/ln(1.032)=y-1985

y=1985+ln(3.812825)/ln(1.032)

y≈2027.5  

So GDP will reach 2.2 trillion during the year 2027.

3abc + b = 5 solve for c
oee [108]

Answer:

c=5-b/3ab

Step-by-step explanation:

What you do is you have to get c by itself.

First you will subtract the b on both sides to get 3abc=5-b.

You will then divide 3ab to get c by itself on both sides.

c=5-b/3ab is your answer.
