Hello from MrBillDoesMath!
Answer:
The first choice, Pi + (-Pi) = 0
Discussion:
Pi is an irrational number. Saying the irrational numbers <u>are</u> closed under addition means if we add two irrational numbers we will get another irrational number. In our case, Pi + (-Pi) = 0, which is correct, BUT 0 is a <u>rational </u>number. This shows the set of irrational numbers is NOT closed under addition.
Thank you,
MrB
(27x + 16*8)/x+8 = 19
(27x +128) /x+8 = 19
multiply both sides by x+8
27x+128 = 19x +152
subtract 19x from both side:
8x +128 = 152
subtract 128 from both side:
8x = 24
divide both sides by 8
x = 24 /8
x = 3 pounds
