Answer:

84

Step-by-step explanation:

Let x = the test

(x + x + ( x - 6))/3=82

((3x - 6)/3) • 3= 82 • 3

3x - 6 + 6 = 246 + 6

<u>3x</u> = <u>252</u>

3        3

x = 84

Answer:

Step-by-step explanation:

I believe that the best advice in this scenario would be to fully pay off the senior dues and with the $48.56 that is left pay back as many lost books as possible. This would leave you owing $6.44 for lost books which you can ask Chris can ask his parents or work a small side gig to earn that money. The more important payment to make is the senior dues which have an actual due date unlike the lost books and can actually cause you trouble if not paid on time.

PLEASE HELP MULTIPLE CHOICE
san4es73 [151]

Answer:

7. C

8. B

9. B

Step-by-step explanation:

7: A proper fraction is a fraction where the numerator is greater than the denominator. Choice <em>a</em> is a decimal, not a fraction. Choice <em>b</em> is a fraction, but its numerator is equal to its denominator. Choice <em>d</em> is also a fraction, but its denominator is greater than its numerator. Choice <em>c</em> is correct, because it is a fraction where its numerator is greater than its denominator.

8. A decimal fraction has denominators like 10, 100, 1000, as so on. It is a fraction.

9. A fraction is equal to the numerator divided by the denominator. When the numerator is equal to the denominator, the value of the numerator divided by the denominator is 1.

Answer:

<em>Functions evaluated at x = -1</em>

A. a(-1) = -2(-1) + 3 = 5

B. b(-1) = 0  (as per graph)

C. <u>Find the equation first:</u>

  • m = 4/8 = 1/2
  • c(x) = 1/2x - 4
  • c(-1) = -1/2 - 4 = -4.5

D.  d(-1) = (-1)² - 4 = -3

E. e(-1) = 2 (as per table)

F. f(-1) = 5/2 = 2.5 (as per graph)

G. g(-1) = 2(3)⁻¹ - 2 = 2/3 - 2 = - 1 1/3

H. h(-1) = 2 (as per table)

<u>The order:</u>

  • C >> D >> G >> B >> E and H >> F >> A
