Okay so first we see the left half is in between "| |" and that means absolute value. That means whatever number is between those lines, you make positive. Now we just plug in the numbers from the choices and see which ones apply.

|27 - 7.5| ≤ 17

|19.5| ≤ 17

19.5 ≤ 17

False. Choice A is not the answer.

|20 - 7.5| ≤ 17

|12.5| ≤ 17

12.5 ≤ 17

True. Choice B is one of the answers.

|(-9) - 7.5| ≤ 17

|-16.5| ≤ 17

16.5 ≤ 17

True. Choice C is also an answer.

The two that apply are B and C.

Hope that helps!

-9 and 20 are your best bet

If z1= 3+3i and z2=7(cos(5pi/9) + i sin (5pi/9)), then z1/z2= blank

A restaurant manager wants to purchase 200200 sets of dishes. one design costs $1010 per set, while another costs $5555 per s

Sophie [7]

Unless it was a restaurant for the king ..... i am going to assume your
200200 is 200
$1010 is $10
$5555 is $55
$78507850 is $7850

Let x be the number of $10 design set
$10 design set = x
$55 design set = 200 - x

10x + 55(200 - x) = 7850
10x + 11000 - 55x = 7850
55x - 10x = 11000 - 7850
45x = 3150
x = 70
200 - 70 = 130

70 of the $10 design and 130 of the $55 design
