A shop owner made a loss of 12% when he sold an item for $264. What was the cost price of the item?.

Firlakuza [10]

Answer:

The cost of the item was $31.68

Step-by-step explanation:

Things to understand for this type of question!

• Converting

• Percentage

————————————————————

We are trying to find out 12% or $264

Step 1. Use part/whole = part/whole

12% is part of $264 in total

12%/100% = ?/$264

Step 2. Multiply $264 by 12% and divided by 100

12%/100% = $31.68/$264

Therefore, the shop owner loss $31.68

| 7 + m | - 4 > 8

cestrela7 [59]

Answer:

m > 5 or m < -19

Step-by-step explanation:

We are given the Inequality:

$\displaystyle \large{ |7 + m| - 4 > 8}$

First, add both sides by 4.

$\displaystyle \large{ |7 + m| - 4 + 4 > 8 + 4} \\ \displaystyle \large{ |7 + m| > 12}$

Absolute Value Property

$\displaystyle \large{ |a| = \sqrt{ {a}^{2} } }$

Given a = any expressions and b = any positive numbers, zero or any expressions.

$\displaystyle \large{ |a| = b \longrightarrow a = \pm b}$

From the Inequality, change > to equal

$\displaystyle \large{ 7 + m = \pm12}$

Subtract 7 both sides.

$\displaystyle \large{ 7 - 7 + m = \pm12 - 7} \\ \displaystyle \large{ m = \pm12 - 7}$

±12-7 can be 12-7 = 5 or -12-7 = -19

$\displaystyle \large{ m = 5, - 19}$

Refer to the attachment. The region is when the absolute value function is greater than constant function y = 12 or a blue horizontal line.

Since the absolute graph is above constant graph when x > 5 and x <-19.

Therefore,

$\displaystyle \large{ m > 5, m < - 19}$

3) -x + 5 = -11x + 25

konstantin123 [22]

Answer:

x=2

Step-by-step explanation:

-x+5=-11x+25

add +x on both sides -11x+x =-10x

-10x+25=5

subtract 25 on both sides

you get -10x=-20

x=2

Solve the system of equations using the substitution method.

leva [86]

Answer:

The answer to your question is 1.- (37/2, -9/2) 2.- g = 4 and h = 2

Step-by-step explanation:

Data

Equation 1 2x + 8y = 1

Equation 2 x = -3y + 5

Process

1.- Substitute equation 2 in equation 1

2(-3y + 5) + 8y = 1

Expand

-6y + 10 + 8y = 1

Solve for y

8y - 6y = 1 - 10

2y = -9

y = -9/2

2.- Substitute y in equation 2 to find x

x = -3(-9/2) + 5

Simplify

x = 27/2 + 5

x = 27/2 + 10/2

x = 37/2

Solution (37/2, -9/2)

2.-

Equation 1 6g + 8h = 40

Equation 2 -6g + 2h = -20

Process

1.- Add both equations

Result

0 + 10h = 20

Solve for h

h = 20/10

h = 2

2.- Substitute h in Equation 1 to find g

6g + 8(2) = 40

Simplification

6g + 16 = 40

Solve for g

6g = 40 - 16

6g = 24

g = 24/6

g = 4

Solution g = 4 and h = 2
