6x-5y = 15 x=y+3 x= y=

Mathematics

Zina [86]3 years ago

Answer:  x = 0  y = –3

Step-by-step explanation:

We can solve this system by substitution.

use the second equation as a value for x.

Then substitute that value  in place of x in the first equation and solve for y.

6x - 5y = 15 becomes

6(y + 3) - 5y = 15  Distribute 6 × parentheses

6y + 18 - 5y = 15 combine like terms

6y -5y + 18 = 15

y + 18 = 15   Subtract 18 from both sides.

y =15 -18

y = –3

Use this value for y in either equation to solve for x

6x - 5(-3) = 15

6x + 15 = 15    Subtract 15 from both sides, divide by 6 (seems silly!)

x = 0

OR in he second equation,

x = -3 + 3  

Again, x = 0

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>

Ryan has 8 kittens. Two are white. What fraction of the kittens are not white? Write in simplest from.
maxonik [38]

Number of kittens Ryan has = 8

Number of white kittens = 2

Number of not white kittens = 8 -2 = 6

Fraction of number of not white kittens = 6/8

To write the fraction in lowest form find the greatest common factor of numerator and the denominator. Divide the numerator and the denominator by the greatest common factor .

Now the greatest common factor of 6 and 8 is 2.

\frac{6}{8} = \frac{6\div 2}{8\div 2} = \frac{3}{4}
