Answers

Answer 1
Answer: 13m-22=9m-6
4m-22=-6
4m=16
m=4
Answer 2
Answer: 13m-22=9m-6
13m-9m=22-6  <-- integer signs change when it goes to the other side of the  equal to sign
4m=16
m=16/4
m=4

Answer:

2 {x}^(2)  + 6x + 13 = 0

Step-by-step explanation:

- 4 {x}^(2)  - 13 - 2x = 4x - 2 {x}^(2)  \n 4x - 2 {x}^(2)  + 4 {x}^(2)  + 13 + 2x = 0 \n  4 {x}^(2) - 2 {x}^(2) + 4x + 2x + 13 = 0 \n  \purple{ \boxed{ \bold{2 {x}^(2)  + 6x + 13 = 0}}} \n is \: the \: standard \: form \:

Harper works at an electronics store as a salesperson. Harper earns a 6% commission on the total dollar amount of all phone sales she makes, and earns a 5% commission on all computer sales. Harper made a total of $2600 in sales and earned $137 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Harper made and the dollar amount of computer sales she made. Define the variables that you use to write the system.

Answers

Answer:

The system of equations are

x + y = 2600   …….equation (1)

and, 6x + 5y = 13700  ……equation (2)

Explanation:

Let x = amount of sales of phone;

y = amount of sales of computer

For phone, 6% of sales is 6% of x, or 6% * x = 0.06x.

Similarly for computer,

5% of y = 0.05y

Given the total sales; x + y = 2600

And commission; 0.06x + 0.05y = 137; or 6x + 5y = 13700

Therefore the system of equations are

x + y = 2600   …….equation (1)

6 x + 5 y = 13700  ……equation (2)

1. Find the area of the unshaded square 2. Find the area of the large square

3. What is the area of the frame represented by the shaded region

Show steps!!

Answers

The large square is 6 by 6 so it has area 6*6 = 36

The small square is 2 by 2 (since 6-2-2 = 2), so it has area 2*2 = 4

The difference in areas is 36 - 4 = 32 which is the area of the shaded region

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

In summary:

1. The unshaded square (smallest square) has area 4 square inches

2. The area of the large square is 36 square inches

3. The shaded region (area of the frame) has area 32 square inches

Answers

Answer:

57 x + -7

Step-by-step explanation:

Simplify the following:

6 9 x + 3 x - 5 - 2

6×9 = 54:

54 x + 3 x - 5 - 2

Grouping like terms, 54 x + 3 x - 5 - 2 = (54 x + 3 x) + (-2 - 5):

(54 x + 3 x) + (-2 - 5)

54 x + 3 x = 57 x:

57 x + (-2 - 5)

-2 - 5 = -7:

Answer:  57 x + -7
