Answer:
Wrong problems = 32
Step-by-step explanation:
Total no of problems = 200
Charlotte earned a grade of 84% on her multiple-choice.
Correct problems,

Wrong problems = 200 - correct problems
= 200 - 168
= 32
Hence, there are 32 problems on the final exam Charlotte get wrong.
If 2a = -10, that means a = -5 Because 2(-5) makes -10.
Thus, -6(-5) = 30 #
Therefore, -6a = 30
Answer:
uh i cant see
Step-by-step explanation:
i cant see what ur talking about
2x + 5y = -8 . . . (1)
-133x - 4y = -8 . . . (2)
(1) * 4 => 8x + 20y = -32 . . . (3)
(2) * -5 => -665x + 20y = 32 . . . (4)
(3) - (4) => 673x = 0
x = 0
From (1), 2(0) + 5y = -8
5y = -8
y = -8/5
