Can someone please help me with 2 math questions. 1. A TV is on sale for $399, or 16% off. What was the original price of the TV? Show your work.
2. A computer is on sale for $450.50, or 15% off. What was the original price of the computer? Show your work.

Step-by-step explanation:

1) $399 = 84% of the original amount

Divide both sides by 84 to get what one percent would be

$4.75 = 1%

Then multiply both sides to get one hundred percent [the original price]

$475 =100%

Use this method to do the second question

$450.50 = 85%

Divide by 85

$5.30 = 1%

Multiply by 100

$530 = original price

answer: i don't understand it

step-by-step explanation: sorry

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
