Step-by-step explanation:
30,42,54,66,78
counting by 12
We can find this using the formula for arc length (where 
is the radius of the circle and 
is the central angle in radians):
In our problem, we are given 
. This means that:
The measure of the angle is 1.5.
Answer:
y = x + 53
Step-by-step explanation:
Let x be the number of flowers Jamal planted and y the number of flowers Heidi planted.
Jamal planted 53 fewer flowers than Heidi:
x = y - 53
Isolate the y.
x + 53 = y (Change the - sign to + sign when switching from different sides of an equation)
y = x + 53
