3.) 2 × 0.5 = 1
4.) -2 × -0.5 = 1
Answer:
I believe it would be - (n+4) x 2
Step-by-step explanation:
We need to subtract: the scientist needed 57,500 dollars, but already had 32,506, so we need to find what's left: 57,500 - 32,506 = 24,992 dollars
Your answer is A. Hope that helps! :)
It would be: k+3 = 10
subtracting 3 from both sides,
k+3-3 = 10-3
k=7
90 degrees exactly. It is four 90 degree angles
