Answer 1
Answer: 9.       ¹/₃(x + 6) = 8
    ¹/₃(x) + ¹/₃(6) = 8
           ¹/₃x + 2 = 8
                  - 2  - 2
            3 · ¹/₃x = 6 · 3
                     x = 18

15.       ¹/₅(x + 10) = 6
      ¹/₅(x) + ¹/₅(10) = 6
                ¹/₅x + 2 = 6
                       - 2  - 2
                 5 · ¹/₅x = 4 · 5
                         x = 20

20.       ¹/₈(24x + 32) = 10
      ¹/₈(24x) + ¹/₈(32) = 10
                     3x + 4 = 10
                           - 4   - 4
                           3x = 6
                            3     3
                             x = 2

32.        5 - ¹/₂(x - 6) = 4
      5 - ¹/₂(x) - ¹/₂(-6) = 4
              5 - ¹/₂x + 3 = 4
              5 + 3 - ¹/₂x = 4
                    8 - ¹/₂x = 4
                 - 8            - 8
                -2 · (-¹/₂x) = -4 · (-2)
                             x = 8

33.      ²/₃(3x - 6) = 3
     ²/₃(3x) - ²/₃(6) = 3
                2x - 4 = 3
                    + 4 + 4
                     2x = 7
                      2     2
                       x = 3¹/₂

A used automobile dealership recently reduced the price of a used compact car by 6%. If the price of the car before discount was 18,400, find the discount and the new price

Answers

Answer:  Discount Price = $1104

New Price = $17296

Step-by-step explanation:

Given : A used automobile dealership recently reduced the price of a used compact car by 6%, which can be written as 0.06.

The price of the car before discount was 18,400.

Formula for Discount = Discount percentage× Original price

Then , Discount =0.06*18400=\$1104

New Price after Discount = Original Price - Discount price

=\$18,400-\$1104=\$17296

Hence, Discount Price = $1104

New Price = $17296
6% of $18,400 = .06 x $18,400 or $1104 - that's the discount

$18,400
-   1,104
$17,296  - this is the new price after the discount

What is the surface area of a prism whose bases each have area 16 and whose lateral surface area is 65

Answers

Formula for Surface Area of a Prism: lateral area + area of 2 ends
Lateral area = 65

The perimeter of a church window is 60 inches. If the window is in the shape of a regular pentagon, what is the length of each side of the window? A. 10 inches
B. 6 inches
C. 12 inches
D. 8 inches

Answers

We have to calculate the length of each side of the regular pentagon and to choose correct answer . It is given that the perimeter of the pentagon is 60 inches. And the perimeter is : P = 5 * L, where L stays for the length of each side. 60 in = 5 * L; L = 60 : 5; L = 12 in. Answer: C. 12 inches.

suppose it has been determined that the probability is 0.6 that a rat injected with cancerous cells will live. if 35 rats are injected, how many would be expected to die

Answers

Answer:

Calculating this, we find that approximately 14 rats would be expected to die.

Step-by-step explanation:

determine the number of rats expected to die, we need to multiply the probability of dying (1 - 0.6 = 0.4) by the total number of rats injected. Probability of dying = 1 - Probability of living = 1 - 0.6 = 0.4 Number of rats expected to die = Probability of dying * Total number of rats injected = 0.4 * 35

Answers

i know this is really late but its for people here now (like me) the answer would be x= -3 1/9
21/7 + 3/7(3x - 5) = -4
21/7 + 9/7x - 15/7 = -4.....multiply everything by 7
21 + 9x - 15 = - 28
9x + 6 = -28
9x = -28 - 6
9x = - 34
x = -34/9 or - 3 7/9
