Which situation can be modeled by the inequality 60−15x≥7?

a. you borrowed $60 from your older brother. you pay him $7 a week and need to pay him back within 15 weeks.

b. you can buy playlists in packages of 15 songs. you have $60 to spend but want to have at least $7 left

c. you owe your parents $60 and plan to pay them $15 a week until you owe them less than $7.

d. you have $60 to spend on hats at the mall, but you need to save at least $7 for lunch. you plan to spend the rest on hats that cost $15 each (including tax).

D

Step-by-step explanation:

To find a situation for 60−15x≥7, look for a story where 60 is a constant value that is decreasing by 15 for a number of times and where equal to or at least 7 is an option.

A. x would be weeks and it would decrease by 7x. This is not it.

B. 15 songs packages would have x be the number of packages not the price. This is not it.

C. This doesn't work either because if you want to owe them less than 7 it would have the sign < not >.

D. You have 60 to spend and you decrease it by $15 for each hat you buy till you save $7. This is it.

4 & 3

step-by-step explanation:

factor of 108=2×2×3×3×3=2×2×3^3=the number is 4 because 2 only occurs 2 times and 2×2=4 and factor of 2187=3^3×3^3×3=the number is 3 because 3 onlyvoccur 1 time.
