olya-2409 [2.1K]

Answer:

w=15

v=6

Step-by-step explanation:

Interior Angle Theroum , we can write

        5 v = 2 w                           (1)

The measures of a pair of​ same-side exterior angles are supplementary

        10 w  + 5 v= 180                (2)

substitute 1 from 2

        10  w + 2 w = 180

         12 w = 180

             w=180/12

              w=15

The measures of a pair of alternate interior angles are

           5 v=2 w

           5 v=2(15)

           5 v=30

           v=30/5

           v=6

I have 31 stamps in total. I have 4 more 1 cent stamps than 8 cent stamps and twice as many one cent stamps as 12 cent stamps. I
Neko [114]

Answer:

There area 14 one cent stamps

Step-by-step explanation:

Let

x -----> the number of 1 cent stamps

y -----> the number of 8 cent stamps

z -----> the number of 12 cent stamps

we know that

0.01x+0.08y+0.12z=1.78 -------> equation A

x=y+4 ------> y=x-4 -----> equation B

x=2z -----> z=0.5x ------> equation C

substitute equation B and equation C in equation A and solve for x

0.01x+0.08(x-4)+0.12(0.5x)=1.78

0.01x+0.08x-0.32+0.06x=1.78

0.15x=1.78 +0.32

0.15x=2.10

x=14

therefore

There area 14 one cent stamps
