Answer:
10
Step-by-step explanation:
The sum of all the interior angles of a pentagon is 540°
So...
540 = 12x + 7x + 16x+ 9x + 10x
Combine like terms:
540 = 12x + 7x + 16x+ 9x + 10x
540 = 54x
Divide by 54 on both sides:
540 = 54x
/54 /54
10 = x
Hope this helps :)
Answer:
they sold 14 pizzas all day.
Step-by-step explanation:
4 x 2 = 8
0.5 means half of what they sold in the afternoon

now add them both together to get the number of pizzas they sold at night.
8 + 2 = 10
now add the afternoon and night together
10 + 4 = 14
answer: 14 pizzas
