Answer 1
Answer: Lets solve this step by step.A is not a positive because (-9)*8=-72.B if positive because -12*(-3)=36. A negative times a negative is a positive.C is also a positive because (-2/5)*(-4) is a positive.D is not a positive because like A, one is negative and the other number is positive. A negative times a positive is a negative.I hope it helped!
Answer 2
Answer: We need to solve this by looking at each answer choice.

A. - (w)/(9)=8

To solve for w, we need to multiply by -9 on both sides.

So, -(w)/(9) * -9 = 8 * -9\n\nw = -72

This is not a positive solution. So eliminate A.

B. (-12) = (y)/((-3))

To solve for y, we need to multiply by -3 on both sides.

So, (-12) * (-3) = (y)/((-3)) * (-3)\n\ny = 36

This is a positive solution. This is one of our answers.

C. [tex]-4* (-5)/(2)= -(2)/(5)z* -(5)/(2)\n\nz = 10[/tex]

We need to multiply by -5/2 on both sides to solve for z.

This is a positive solution. This is one of our answers.

D. (1)/(7)x = -2

We need to multiply by 7 on both sides to solve for x.

So, (1)/(7) x * 7 = -2 * 7\n\nx = -14

This is a negative solution. So this is not the answer.

So your final answer is B and C.
