A package of cookies has 6 chocolate chip cookies with nuts and 12 chocolate chip cookies without nuts. Which of these represents the ratio of cookies with nuts to total cookies?

6:18

Step-by-step explanation:

Number of cookies with nuts = 6

number of total cookies = no. of cookies WITH nuts + no. of cookies WITHOUT nuts.

= 6 + 12 = 18

Ratio of

Number of cookies with nuts : number of total cookies

                      6                        :                    18

6:18 is the ratio of cookies with nuts to total cookies.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

answer: 12   they all have at least 28 days
