In 8-11, Explain how to get the variable alone in each equation

8. 8y = 5.6

9. x ➗ 15.2 = 3

10. u ➗ 8.7 = 12

11. 31.4 = 3.14y

Answers

Answer 1

Step-by-step explanation:

8. You divide each side by 8

[tex] \frac{8y}{8} = \frac{5.6}{8} [/tex][tex]y = \frac{5.6}{8} [/tex]

9. You multiply each side by 15.2

[tex]x = 3 \times 15.2[/tex]X=45.6

10. You multiply bith sides by 8. 7

[tex]u= 12 \times 8.7[/tex]

11. You divide both sides by 3.14

[tex]3.14y = 31.4 \\ y = \frac{31.4}{3.14} \\ y = 10[/tex]

Hope this helps, have a wonderful day

Two years ago, Jose bought $750 worth of stock in a cell phone company. Since then the value of his stock has been DECREASING at an average rate of 5 1/4 % per year. How much is the stock worth now?

Answers

Answer:

$671.25

Step-by-step explanation:

To get the amount by which the stock have reduced after 2 years, we will use the interest formula;

Interest = Principal * rate * time/100

Interest = 750*5 1/4 * 2/100

Interest = 750*21*2/400

Interest = $78.75

This means that the value of the stock has reduced by $78.75 after 2 years;

Amount that the stock worth now = $750 - $78.75

Amount that the stock worth now = $671.25

A coin collection consists of dimes and nickels. If there are a total of 500 coins valued
at $39. how many dimes are there?

Answers

Answer:

There are 280 dimes

Step-by-step explanation:

A nickel is worth 5 cents while a dime is worth 10 cents

Let n be number of nickel

d the number of dimes

n + d = 39

Secondly

$39 is same as 3900 cents

So we have;

10d + 5n = 3900

From first equation;

n = 500-d

Put this in second equation;

10d + 5(500-d) = 3900

10d + 2500-5d = 3900

5d = 3900-2500

5d = 1400

d = 1400/5

d = 280

Answer:

           The first:    y = -25x + 180

Step-by-step explanation:

In every equation b = 170, so

The equation is  y =mx + 170

On the line on the graph, for x=2 we have y = 120,so:

 120 = m×2 + 170

 -50 = 2m

   m = 25

Therefore the equation is:

                                          y = -25x + 180

Solve the equation for x:
-3(x + 4) + 5x = 24

Answers

Answer:

[tex]-3(x + 4) + 5x = 24\\\\-3x - 12 + 5x = 24\\\\2x - 12 = 24\\\\2x = 36\\\\x = 18[/tex]

The solution for x in this equation is 18.

Answer:

x = 18

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

-3(x + 4) + 5x = 24

Step 2: Solve for x

Distribute -3:                    -3x - 12 + 5x = 24Combine like terms:        2x - 12 = 24Isolate x term:                  2x = 36Isolate x:                           x = 18

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                     -3(18 + 4) + 5(18) = 24Add:                                      -3(22) + 5(18) = 24Multiply:                                -66 + 90 = 24Add:                                      24 = 24

Here we see that 24 does indeed equal 24.

∴ x = 18 is the solution to the equation.

A gift basket has 2 soaps and 5 lotions and costs $20. A second basket has 6 spas and 15 lotions and cost $60. Is it possible to determine the price of the soap?

Answers

A second basket has 6 spas--- I think you mean 6 soaps , so i will work with that

Answer:it is not possible to determine the price of the soap with the information given.

Step-by-step explanation:

Let s0ap be represented as x

and lotion be represented as y

2 soaps and 5 lotions costing  $20 gives us equation 1 as

2 x+ 5y= 20-------- equation 1

second basket with 6 soaps and 15 lotions and costing $60 gives us equation 2 as

6x + 15y= 60------equation 2

Step 2 -- Solving

2 x+ 5y= 20-------- equation 1

6x + 15y= 60--------equation 2

BY elimination method, we  multiply equation 1 by (3)

2x + 5y= 20  x (3)

6x + 15y=60-------equation 3

Subtraction of equation 3 from equation 2 gives us

6x + 15y=60-------equation 3

-6x + 15y= 60--------equation 2

0x +0y=0  which is no solution

Therefore it is not possible to determine the price of the soap

Answer:

x = x + 7

Step-by-step explanation:

In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.
