Iven: x + 2y = -6. Solve for y.

y = -x/2 -3

Step-by-step explanation:

So there are LOTS of ways you can choose to do this, but this is how i do it:

I like to move all the x to one side first, so:

2y = -x -6

Then we have to divide everything by 2 to get y on its own:

y = -x/2 -3

*you can divide first too if you want, i find that this keeps it nice and simple though

Hope this helped : )

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'.
