Answer:

Yes.

Step-by-step explanation:

According to the Transitive property of the Algebraic properties of equality, two values are said to be equal is they are differently equal to a corresponding third party. This is, If a=b and b=c then a=c.

Hence, if x=5 and 5=y, then following the transitive property of Algebraic properties of equality, x=y, hence the Algebraic property of equality Justifies the statement.

A convenience store purchased a magazine and marked it up 100% from the original cost of $2.30. A week later, the store placed t

Answer:

$2.30

Step-by-step explanation:

The original price is $2.30 an it goes up by 100% which means another 2.30. So add 2.30 and 2.30 together you get 4.60 now divide that by two since the magazine is 50% off and you get the original price which was 2.30

Find the solution set. (x+7)(x+7)=0

levacccp [35]

For this case we must find the solution of the following expression:

$(x + 7) (x + 7) = 0$

If we isolate a term and we equate to zero, we have:

$x + 7 = 0$

Subtracting 7 on both sides of the equation we have:

$x + 7-7 = 0-7\\x = -7$

Thus, the solution of the expression is given by:

$x = -7$

ANswer:

$x = -7$

An item was sold at a loss of 20%. Had it been sold for Rs 3000more then the profit would have been 10%. What is the cost price

vagabundo [1.1K]

Answer:

Cost Price = Rs 10000

Step-by-step explanation:

Assume:

Cost of the item = x

Item was sold at a loss of 20%:

Loss = 20% of x = 0.2x

Item sold = x - 0.2x = 0.8x

Item sold at a profit of 10%:

Profit = 10% of x = 0.1x

item sold = x + 0.1x = 1.1x

Solve:

Difference = 1.1x - 0.8x = 0.3x

0.3x = Rs 3000

x = Rs 3000 ÷ 0.3

x = Rs 10000
