HELP ME ASAP. The answer is -10 but explain it how to do it step by step. -6+(-30) divided by 5-(-2)
Alex777 [14]

Step-by-step explanation:

Following the order of operations we would first divide -30 by 5 which would give us -6

-6 + (-30) ÷ 5 - (-2)

From here we can add -6 + -6 = -12

-6 + (-6) - (-2)

When subtracting a negative number, the two negatives changes it to a positive. (-12) - (-2) = (-12) + 2 which would give us -10

(-12) - (-2) = -10

~Hope this helps!~
