18+6x?= 168
try taking away the 18 and 6 then dividing it
Combined speed = 95+75= 170 mph
they will meet in 306/170 = 1.8 hours or 1 hour 48 minutes.
4.05 in a mixed number is 4 1/2
One of the three economic questions deals with deciding what goods and services must be produced from available resources.

X = 10
The triangles are similar by SAS, so we can set up a proportion of their sides.
9/(33-9) = 12/(3x+2)
9/24 = 12/3x+2
Reduce
3/8 = 12/3x+2
Cross multiply
3(3x+2) = 12*8
Distribute and multiply
9x + 6 = 96
Subtract 6
9x = 90
Divide by 9
x = 10
Check:
9/24 = 12/3x+2
9/24 = 12/3*10 + 2
9/24 = 12/30 + 2
9/24 = 12/32
3/8 = 3/8 :)
