Let the number sold of veggie pizza be a
The number sold of cheese pizza be b
a+b=25…1
A+7=b…2
Sub 2 into 1
a + a+7 = 25
2a+7=25
2a=18
a=9
Sub a=9 into 2
9+7=b
b=16
They sold 9 veggie pizza and 16 cheese pizza
Use sin, cos, tan formula
Answer:
40 inches
Step-by-step explanation:

53.33×3=159.99
159.99÷4=39.9975
39.9975 rounded would be 40
Here we will use exponential form, which is

Initial value, y0 = 500
Double of 500 = 1000



Required equation is

Answer:
A
Step-by-step explanation:
