457.50 + 30.99 + 42.62 + 199.87= 730.98
1225-730.48= $494.02
3 / (4/9)
First, let's multiply the top and bottom by 9 to get rid of the fraction in the denominator.
27 / 4 is the final answer.
Answer:
half of 84 is 42. Since the total difference is 18 meters you will increase one by 9m and decrease the other by 9m....therefore 42-9=33. 42+9=51
33
51
Answer:
1668 feet.
Step-by-step explanation:
We know the opposite side of the right triangle and we need the adjacent side, so we use the tangent function.
If the distance required is x (adj side) we have:
tan 41 = opp/adj
tan 41 = 1450/x
x = 1450 / tan 41
= 1668.03
I think you meant...
3^(3x-7)=81^(12-3x) (note that 81=3^4) so
3^(3x-7)=3^4^(12-3x)
3^(3x-7)=3^(48-12x) taking log or natural log of both sides show that
3x-7=48-12x
15x=55
x=11/3
