Carol has 3 children. the youngest child is 4 years younger than the middle child. the oldest child is 6 years older than the middle child. the youngest child is 8. the sum of their ages is 12 years less than carol's age. how old is carol?

let c = carol's age; y = youngest child.

a) c=y+(y+4)+(y+4+6)+12
b) c=y-(y--4-6)-12
c) c+12=y+(y+4)+(y+4+6)
d) c=y+(y-4)+(y-4-6)+12

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
