9+ (-11) - 4 + (-8) - 10= what is the answer?

We can solve using BEDMAS.
We also must work from left to right.

-9 + (-11) - 4 + (-8) - 10=
-9 - 11 - 4 + (-8) - 10=
-20 - 4 + (-8) - 10=
-24 + (-8) - 10=
-24 - 8 - 10=
-32 - 10
= -42

The answer would be -42

Hope this helps!

Two possible answers are:

2/20 gallons per minute and 3/30 gallons per minute.

Explanation:

To find equivalent ratios, we are finding equivalent fractions.  To do this, we would multiply the numerator and denominator of the original fraction, 1/10, by the same constant.

(1*2)/(10*2) = 2/20 and (1*3)/(10*3) = 3/30.
