5x -15 + 3 -8x = 13
5x -12 -8x = 13
5x -8x =13 -12
-3x = 1
x = -1/3
Answer:
53 minutes
Step-by-step explanation:
Let x be the time required for a full video upload. This would have the unit of (minutes/full upload). Since the upload rate is constant, we can write:
(0.17)*(x) = 9 minutes
This equation states that 17% of the full upload time is 9 minutes.
Solve for x:
x = (9 minutes)/(0.17)
x = 52.9 minutes or 53 minutes with 2 sig figs
$3,500 budget minus $50 clean up fee equals $3,450.
3500 - 50 = 3450
$3,450 divided by $31 per person equals 111.29
3450 / 31 = 111.29
111 people multiplied by $31 equals $3,441 plus $50 clean up fee equals $3,491
111 x 31 = 3441
3441 + 50 = 3491
They can invite 111 people and will have $9 to spare
