Step-by-step explanation:
1/2x-4=-2x-9...u vil get the ans
8
3+5=8
What is the question?
B
7.3×10^22 = 73,000,000,000,000,000,000,000
73,000,000,000,000,000,000,000 × 26,000,000 = 1,898,000,000,000,000,000,000,000,000,000 or 1.898 × 10^30
-4u - w = u + 6w
-4u = u + 7w (Add w to both sides)
-5u = 7w (Subtract u from both sides)
w = (Divide both sides by 7)
