Answer:
x = 8/3
Step-by-step explanation:
6x-4=3x+4
Subtract 3x from each side
6x-3x-4=3x-3x+4
3x-4 =4
Add 4 to each side
3x-4+4 = 4+4
3x =8
Divide each side by 3
3x/3 = 8/3
x = 8/3
A movie theater had 1200 seats arranged in a number of identical rowa. After the number of seats in every row had been increased by 3 and 2 rowa have been removed, the total number of seats in the theater then increased by 4. How many seats where there in each row originally

TSA = 2πrh + 2<span>πr^2
</span>TSA = 471 + 157 (or 150π + 50π)
TSA = 628 cm^2 (or 200π)
8b
628 x $3 = $1884
cost = $1884

V = πr^2h = π 5^ 5 (15) = 375π (or 1177.5 if use π = 3.14)
