Noah buys 3 packages of pens each package has four blue pens and two black pens which equation can be used to find p

p = 3*[ 4p+ 2p]

Step-by-step explanation:

Total number of pens = 3 times [ 4 blue pens + 2 black pens]

If we denote the total number of pens by p then the equation becomes

p = 3*[ 4.blue + 2black]

p = 12p+6p

p = 18p

There are total 18 pens out of which 12 pens are blue and 6 pens are black.

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
