Ana age is 8 years less than 4 times her sister's age .write an expression for ana's age. how old is ana if her sister is 5 years old ?

4x - 8 ; 12 yrs old

Step-by-step explanation:

sister: x

Ana: 4x - 8

when x = 5, Ana = 4(5) - 8

                           = 20 - 8

                           = 12

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
