Simplify the expression.
3g- 9+ 11g - 21
The simplified expression is

g = -0.8571428571

Step-by-step explanation:

3g + -9 + 11g + 21 = 0

Reorder the terms:

-9 + 21 + 3g + 11g = 0

Combine like terms: -9 + 21 = 12

12 + 3g + 11g = 0

Combine like terms: 3g + 11g = 14g

12 + 14g = 0

Solving

12 + 14g = 0

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '-12' to each side of the equation.

12 + -12 + 14g = 0 + -12

Combine like terms: 12 + -12 = 0

0 + 14g = 0 + -12

14g = 0 + -12

Combine like terms: 0 + -12 = -12

14g = -12

Divide each side by '14'.

g = -0.8571428571

Simplifying

g = -0.8571428571

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

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.
