80 divided by (6 + (3 - 5) X 2)

40

Step-by-step explanation:

remember PEMDAS

our equation looks like tihs:

1. parentheses: in the denominator we have a parentese inside of another parenthese, so start with the inside first: (3-5) = -2.

so now our equation looks liek this

now we have a mini PEMDAS situation within the parentheses: multiplication comes before addition/subtraction, so multiply -2*2 = -4, so now your equation looks like this:

6-4 =2: so now we're done with parentheses part of PEMDAS, the only thing left is dividing 80/2 which equals 40.

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
