  • Answer:

<em>1. x = - 7/3 = - 2  1/3</em>

<em>2. x = -2</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em />

<em>3x + 12 = - 6x - 9</em>

<em>3x + 6x = - 12 - 9</em>

<em>9x = - 21</em>

<em>x = - 21⁽³/9</em>

<em>x = - 7/3</em>

<em>x = - 2  1/3</em>

<em />

<em>12x + 20 = 2x</em>

<em>12x - 2x = - 20</em>

<em>10x = - 20</em>

<em>x = - 20/10</em>

<em>x = - 2</em>

<em />

<em>Good luck !</em>

Let mZA = 40°. If zB is a complement of ZA, and ZC is a supplement of ZB, find these measures.
seraphim [82]

Angle b= 50

Angle c= 130

Complementary angles are two angles that add to equal 90

Supplementary angles are two angles that add to equal 180

To find the measurement of angle b, subtract 40 from 90 (50)

To find the measurement of angle c, subtract 50 from 180 (130)

Jim owns stock in Gamma Vision Inc. That company announces that it will split its stock with three new shares per two old shares
ruslelena [56]

Answer:

<u>The correct answer is C. 600 shares worth $16.67 each </u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of old shares Jim owns in Gamma Vision Inc = 400

Value of each share = $ 25

Ratio of new shares : old shares after the split = 3:2

2. How many shares will he have after the split and how much will each be worth? Select the best answer from the choices provided.

A. Let's use the ratio provided to calculate the number of new shares Jim will own, this way:

New shares = 400 * 3/2 = 1,200/2 = 600

B. Let's calculate the price of the new share, this way:

The total value of the new shares should be the same than the total value of the old shares, then:

400 * 25 = 600 * x

10,000 = 600x

x = 10,000/600 = 16.67

<u>The correct answer is C. 600 shares worth $16.67 each </u>
