Answer:
$8.00
Step-by-step explanation:
Jill had a total score of 40 on 13 quizzes, so her average was
40/13 ≈ 3.08
_____
1 quiz @ 1 = total of 1
3 quizzes @ 2 = total of 6
4 quizzes @ 3 = total of 12
4 quizzes @ 4 = total of 16
1 quiz @ 5 = total of 5
total score = 1 + 6 + 12 + 16 + 5 = 40
total quizzes = 1 + 3 + 4 + 4 + 1 = 13

answer:
=1
explanation:
you need to add the exponents, so 5-5= 0 and a number to the 0 is 1
Answer: <em>x</em> = -2
Work:
Convert 216 = 6³
Therefore: 6³ = 6^(4x+11)
⇒ Bases cancel out:
3 = 4x + 11 ⇒ Subtract 11 from both sides
-8 = 4x ⇒ Divide both sides by 4
x = -2
