Step-by-step explanation:

3.

add like terms

30 + 7k = 100

100-30 = 70

70 divided by 7k = 10

k = 10

4. add the z's together

2z - 6 -2 = -10

+ 6 + 2

-10 will be -2 now since we dragged the -6 and -2 to the other side

2z = -2

z = -1

5. 3.2x - 1.7x = 1.5x

1.5x + 5.5 = 10

10 would be 4.5 since we dragged 5.5 to the other side so it would be 10 - 5.5

3.2x = 5.5

x = 1.71875

6.

3/4x - 1/4x = 2/4x

14 - 3 = 11

2/4x = 11

x = 22

Answer:

Step-by-step explanation:

1. Undo the operations done to n, in reverse order. Here, n has r added and the sum is multiplied by m. First we divide by m, then we subtract r.

  m(n+r) = s . . . given

  n +r = s/m . . . divide by m

  n = (s/m) -r . . . subtract r

__

2. Eliminate the parentheses, then proceed as above. Subtract the added term, then divide by the coefficient of n.

  m(n+r) = s

  mn +mr = s . . . eliminate parentheses

  mn = s -mr . . . subtract the added term

  n = (s -mr)/m . . . divide by the coefficient of n

Answer:

y = -10

Step-by-step explanation:

(-7x+3y) - (-7x +10y) =-65 -(-135)

-7x + 3y + 7x -10y = 70

-7y = 70

y = -10

The equation that results from subtracting - 7x + 3y = - 65 and

- 7x + 10y = - 135 is 7y = - 70.

We know two simultaneous equations have a unique solution when they intersect at a point,

when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.

Given, a system of equations - 7x + 3y = - 65 and - 7x + 10y = - 135.

Subtracting the first equation from the second we get,

   - 7x + 10y = - 135

(-) - 7x + 3y =    - 65

_________________

Negative sign gets distributed

   - 7x + 10y = - 135

  + 7x - 3y =   + 65

_________________

            7y =   - 70

              y =   - 70/7

              y =  - 10.

So, the value of x is -7x +10×(-10) = - 135.

- 7x - 100 = - 135.

- 7x = - 135 + 100.

- 7x = - 35.

x = 7.

Answer:

10 liters

Step-by-step explanation:

x=12% solution, y=16% solution

x+y=40

0.12x+0.16y=6 .   (12x+16x=600)

-12x-12y=-480

      12x+16x=600

+     -12x-12y=-480

-------------------------------

             4x=120

x=30

12% solution= 30 liters

16% solution= 10 liters

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

10L of the 12% of solutions and 30L of the 16% of solutions were used to produce 40L of the 15% of solutions.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Let 12% brine solution be x.

Let 16% brine solutions be y.

12% brine solution was mixed with a 16% brine solution to produce 40L of the 15% solution.

This can be written as,

x + y = 40 ______(1)

0.12x + 0.16y = 0.15 x 40

0.12x + 0.16y = 6 _______(2)

We will solve for x and y.

From (1) we get,

x + y = 40

x = 40 - y _____(3)

Putting ( 3) in (2)

0.12 (40 - y) + 0.16y = 6

4.8 - 0.12y + 0.16y = 6

4.8 + 0.04y = 6

0.04y = 6 - 4.8

0.04y = 1.2

y = 1.2/0.04

y = 30

Putting in (3) we get,

x = 40 - 30 = 10

Thus,

10L of the 12% of solutions and 30L of the 16% of solutions were used to produce 40L of the 15% of solutions.

12,500.

Step-by-step explanation:

We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $25. Option B is a commission rate of 8% on weekly sales.

First of all we will find amount earned by salesperson with option A.

\text{Option A earnings}=40\times 25=1000Option A earnings=40×25=1000

The salespersons earns $1000 through option A.

Let x be the amount of weekly sales.

8% of x should be equal to 1000 for salesman to earn the same amount with the two options.

\frac{8}{100}x=1000

100

8

x=1000

0.08 x=10000.08x=1000

x=\frac{1000}{0.08}x=

x=12500x=12500

Therefore, the salesman needs to make a weekly sales of $12,500 to earn the same amount with two options.

Answer:

148x+76y=3640

The orchestra tickets costed $21, the balcony tickets costed $7

Step-by-step explanation:

You do 148x because we know that they sold 148 tickets we just need to know the cost and 76 because we know that have sold 76 balcony tickets.

I’m don’t really know how to say the rest

The price of each ticket will be;

The price of balcony ticket = $910

So, The price of orchestra ticket = $2730

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A theater earns $3640 from a concert.

And, An orchestra ticket costs three times as much as a balcony ticket.

Now,

Since, An orchestra ticket costs three times as much as a balcony ticket.

Let price of balcony ticket = x

So, The price of orchestra ticket = 3x

Hence, We can formulate;

⇒ x + 3x = $3640

⇒ 4x = $3640

⇒ x = $3640/4

⇒ x = $910

Thus, The price of balcony ticket = x

                                                   = $910

So, The price of orchestra ticket = 3x

                                                  = 3 × $910

                                                  = $2730

Thus, The price of each ticket will be;

The price of balcony ticket = $910

So, The price of orchestra ticket = $2730
