Answer:
u=−x2−x+1
Step-by-step explanation:
Let's solve for u.
2x−u−1x^2−3x+3=2
Step 1: Add x^2 to both sides.
−x2−u−x+3+x2=2+x2
−u−x+3=x2+2
Step 2: Add x to both sides.
−u−x+3+x=x2+2+x
−u+3=x2+x+2
Step 3: Add -3 to both sides.
−u+3+−3=x2+x+2+−3
−u=x2+x−1
Step 4: Divide both sides by -1.
−u/−1=x2+x−1
−1/u=−x2−x+1
Answer:
u=−x2−x+1
43.8 + x = 46.59
x = 46.59 - 43.8 ( when you move a number to the other side, flip the sign)
x = 2.79 (answer)

B) 14 is the correct answer
Answer:
part A: 10.52
part B: 67.33
Step-by-step explanation:
part a:52.60 x 0.20=10.52
part b:52.60 x 0.08=4.2080
4.2080 about equal to 4.21
52.60 x 0.20=10.52
the amount of the bill before tax = 52.60
52.60+4.21+10.52=67.33
Here’s the first one, hope this helps
