Answer:
3.5
Step-by-step explanation:
2(5x-9)=17
10x-18=17
+18
10x=35
÷10
x=3.5
or
2(5x-9)=17
÷2
5x-9=8.5
+9
5x=17.5
÷5
x=3.5
Answer:
A
Step-by-step explanation:
because she said half of X so 1/2x and then +3 to that half
Answer:
350 adult tickets were sold
Step-by-step explanation:
Let x represent the number of adult tickets sold.
Since there were 60 fewer student tickets sold than adult tickets, the number of student tickets sold can be represented by x - 60
Create an equation that sets up these terms equal to 640, then solve for x:
(x) + (x - 60) = 640
2x - 60 = 640
2x = 700
x = 350
So, 350 adult tickets were sold
Force = mass x acceleration (F=ma)
When the parachutist reaches terminal velocity they are moving at a constant speed and no longer accelerating so acceleration (a) would be 0
so F would also be 0 since anything multiplied by 0 = 0
this would also mean that Fdrag must exactly balance Fg
so Fdrag would = -Fg, so Fdrag would be -850 N
