Proof:
Work to solve for variable:
(2x + 6)
130-
-M1

Step-by-step explanation:

Regroup terms.

130(2x+6)+M\times 1130(2x+6)+M×1

2 Simplify  M\times 1M×1  to  MM.

130(2x+6)+M130(2x+6)+M

3 Expand by distributing terms.

260x+780+M260x+780+M

Done

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.

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.
