Can i have halp with all and an explanation because i am terrible at properties.

use properties of equality to simplify each of the following expressions so that you can simplify them in your head. identify the properties used and describe how you used them.

1. 4 • (–3) • 5

2. (2.25 • 23) • 4

4. 5 • 12 • (–2)

5. 35(26)(0)

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'.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
