Answer:

x=30

Step-by-step explanation:

The two angles are supplementary. They add to 180

4x+20 + 40 =180

Combine like terms

4x+60 =180

Subtract 60 from each side

4x+60-60 = 180-60

4x = 120

Divide each side by 4

4x/4 = 120/4

x = 30

Naya [18.7K]

Answer:

Step-by-step explanation:

You multiply the number of people by the number of each slices each person gets. Which is 100; 50x2.

Each cake has 20 slices so you divide 100 by 20. Which equals 5.

It would take 5 cakes to feed all 50 people 2 slices each.

Hope this helps. :)
