Martin has 60 magazines and 42 books to put into stacks. Each stack will have 7 magazines and 4 books. How many complete stacks of 7 magazines and 4 books can Ms. Martin make?

8 complete stacks

Step-by-step explanation:

Total magazine = 60

Total books = 42

Each stack will have 7 magazines and 4 books.

Each stack = 7 magazines + 4 books

How many complete stacks of 7 magazines and 4 books can Ms. Martin make?

Number of stack of 7 magazines possible = total magazines / magazines per stack

= 60/7

= 8 4/7

Complete stacks with 7 magazines = 8

Number of stack of 4 books possible = total books / books per stack

= 42/4

= 10 1/2

Complete stacks with 4 books = 10

If 7 magazines on each stacks can make 8 complete stacks

Then, 4 books on each stack can make 8 complete stacks

Note: after 8 stacks using 7 magazines each, magazines will not be available to complete other stacks

i need points

step-by-step explanation:

sorry bubs

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.
