your equation would be n=50.50-18/.05
n=32.5/.05
n= 650
you're correct. its to take out the greatest common factor.
I believe it's the same as adding 8+3, but you add the negative sign to your answer
so 8+3 = (-?)
Answer:
∠ A ≈ 44.42°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos A = 
= 
= 
, then
∠ A = 
( ) ≈ 44.42° ( to the nearest hundredth )
(2/3) / 3 = 1/x...2/3 to 3 lawns = 1 to x lawns
cross multiply
(2/3)(x) = (3)(1)
2/3x = 3
x = 3 * 3/2
x = 9/2 or 4 1/2 lawns can be cut with a full tank of gas
