Answer:
The answer is 10/21 also known a C
39-A
When you multiply 8 times 2 its 16 and 40-16 is 24
40-D
less than is towards the negatives and for less than or greater than you use open circles
Any value of x makes this equation true or all real numbers
-2(3x+12) is the same this as -6x-24 when distributed
so it's -6x-24=-24-6x
her -6x just disappeared so she is wrong :)
