Round 823 to the nearest ten

820

bc it is not 825 or higher it stays the same

820

Step-by-step explanation:

Find the number in the ten place 2 and look one place to the right for the rounding digit 3. Round up if this number is greater than or equal to

5 and round down if it is less than 5.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
