7n - 4 = 31
move -4 to the other side
sign changes from -4 to +4
7n-4+4= 31+4
7n= 31+4
7n= 35
divide both sides by 7 to get n by itself
7n/7= 35/7
cross out 7 and 7 , divide by 7 and then becomes 1*1*n= n
n= 35/7
answer:
n= 5
x=3.5
This is how I did it I took the bottom 2, 3 and 2.4 and I divided 3 by 2.4 (3/2.4) and got 1.25. I then multiplied 2.8 by 1.25 and found that x was 3.5

Answer: 1960.2 cm
Step-by-step explanation:
<em>v = πr^2h</em>
v = π7.4^2(11.4)
= π54.76(11.4)
= 171.9464(11.4)
=<u> 1960.2 </u>
