Cole ate 2/3 of the cookies in the cookie jar. Jim ate 1/4 of the cookies
djyliett [7]

Answer:

6

Step-by-step explanation:

first, we start with 2 dozen = 2 * 12 = 24 cookies

next, cole eats 2/3 of the cookies

2/3 of the cookies = 2/3 * 24 = 16

we are then left with

original # - # of cookies cole ate = 24 - 16 = 8

next, jim eats 1/4 of the cookies left

cookies left = 8

1/4 of cookies left = 1/4 * 8 = 2

cookies left - cookies jim eats = cookies still in jar = 8 - 2 = 6

A line on the coordinate plane passes through the points (7, -5) and (3, 11). A line that is perpendicular to the first line pas
yulyashka [42]
Slope of the line passing through (7,-5) and (3,11) =
\frac{11 - ( - 5)}{3 - 7}
= -4

As two lines are perpendicular to each other, so when their slopes are multiply by each other, the answer will be -1

so the slope of the line passing through (-3,-9) and (5,n) will be
\frac{1}{4}
So will will get a formula below
\frac{n - ( - 9)}{5 - ( - 3)}  =  \frac{1}{4}
and the answer will be n=
- 7

Angle Terminology with Equations
Sergeeva-Olga [200]

Answer:

∠ B = 54°

Step-by-step explanation:

Supplementary angles sum to 180°.

Sum A and B  and equate to 180, that is

7x + 14 + 5x - 26 = 180, that is

12x - 12 = 180 ( add 12 to both sides )

12x = 192 ( divide both sides by 12 )

x = 16

Thus

∠ B = 5x - 26 = 5(16) - 26 = 80 - 26 = 54°
