ok so here is a breif explanation for irrational number,"an irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. instead, the numbers in the decimal would go on forever, without repeating".

first answer,d

2nd=a

3rd=c

example of rational "a rational number is a number that can be written as a ratio. that means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. the number 8 is a rational number because it can be written as the fraction 8/1".

so it would be either c or d.

the first answer is b

the second answer is b

the third answer is c

the fourth answer is b

the last answer is c

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
