-1/9 + (-5/9) write in simplest form

Hope this will help u....

Step-by-step explanation:

Since you have two negative fractions you add them together and put a negative sign in front of the fraction.

1+5=6                                  so you have

                    Now you have to simplify 6 and 9 are both divisible by 3 so                             divide  both by 3 separately and then put it back in fraction form

-6÷3=-2

9÷3=3                    back in fraction form

                     You can't simplify any more so is your answer

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
