50 pts. to correct answers only. simplify to create an equivalent to 3(4z-2) -5x + 10 using the least number of items.

12z - 5x + 4

Step-by-step explanation:

The least number of terms is the most simplified form. Simplify by distributing into the parenthesis and combining like terms.

3(4z-2) - 5x + 10

12z - 6 - 5x + 10

12z - 5x + 4

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
