PS: Explicar resposta

B

Step-by-step explanation:

√16/25 = 4/5 = 0.8-> (4/5 x 4/5 = 16/25)

(2/5)^3 = 8/125  = 0.064

-(-0.3)^3 = 0.027 (an odd exponent mantains the same sign of the number and minus x minus = +)

-√169 = -13

-13 is a negative number so it is surely the smallest

2 is minor than 6 so we have that 0.027 is minor than 0.064

8 is major than 0, so 0.8 is the greatest number

we have

-√169 ; -(-0.3)^3 ; (2/5)^3 ; √16/25

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared

step-by-step explanation:

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%
