Answer:

$67.50

Step-by-step explanation:

First, find the discount.

Multiply the discount rate by the cost.

discount rate * cost

The discount rate is 10% and the cost is $75.

$75 * 10%

Convert 10% to a decimal. Divide 10 by 100 or move the decimal place two spots to the left.

10/100 = 0.10       or         10.0 --> 1.0 --> 0.10

$75 * 0.10

$7.5

Now, find the final price.

Since it is a 10% discount, we must subtract the discount amount from the cost.

cost - discount

The cost is $75 and the discount is $7.5

$75 - $7.5

$67.50

The final price of a item that costs $75 with a 10% discount is $67.50

<h2><u>Question</u><u>:</u><u>-</u></h2>

solve for x: 3(x + 1) = 2 (x -1)

<h2><u>Solution</u><u>:</u><u>-</u></h2>
  • 3(x + 1) = 2 (x -1)
  • 3x + 3 = 2x - 2
  • 3x -2x = -2 -3
  • x = -5

<h2><u>Answer</u><u>:</u><u>-</u></h2>

[Hence, the value of x is -5.]

What is the value of 3 x squared minus 5 x y + 5 y squared for x = negative 6 and y = 2?
Klio2033 [76]

Answer:

A = 188

Step-by-step explanation:

+ replace x = -6 and y= 2 into 3 x squared minus 5 x y + 5 y squared = A

So A= 3x^2 - 5xy + 5y^2

A = 3 *(-6)^2 -5* (-6) *2 +5* 2^2

A = 3* 36 +60 + 5*4

A= 108 +60 +20

or A = 188

Use the subtraction method to solve the system of equations. Choose the correct ordered pair. 2x-y=6
Ber [7]

Answer:

Check for (3, 0)

Put x = 3 and y = 0 in equation 2x – y = 6

2(3) – (0) = 6

6 = 6

<h2>True statement. </h2>

(3,0) is a solution of 2x – y = 6.

(ii) Check for (0, 6)

Put x = 0 and y = 6 in 2x – y = 6

2 x 0 – 6 = 6-6 = 6

<h2>False statement. </h2>

⇒ (0, 6) is not a solution of 2x – y = 6.

(iii) Check for (2, -2)

Put x = 0 and y = 6 in 2x – y = 6

2 x 2 – (-2) = 6

4 + 2 = 6

6 = 6

<h2>True statement. </h2>

⇒ (2,-2) is a solution of 2x – y = 6.

(iv) Check for (√3, 0)

Put x = √3 and y = 0 in 2x – y = 6

2 x √3 – 0 = 6

2√3 = 6

<h2>False statement. </h2>

⇒(√3, 0) is not a solution of 2x – y = 6.

(v) Check for (1/2, -5)

Put x = 1/2 and y = -5 in 2x – y = 6

2 x (1/2) – (-5) = 6

1 + 5 = 6

6 = 6

<h2>True statement. </h2>

⇒ (1/2, -5) is a solution of 2x – y = 6.

Step-by-step explanation:
