we know that
In an Arithmetic Sequence the difference between one term and the next is a constant

where
a1 is the first term
d is the common difference between terms
n is the number of months (in this problem)
case a) Mandy


------> equation 
in this equation the first month is April
case b) Bill


-------> equation 
In this equation the first month is May
With the equation
and the equation
calculate the attached table
therefore
the answer is
December
Answer:
L.C.M of 15 and 30 is 30.
Answer:
The parent function f(x) is equal to 
The translations is 3 units to the left and 5 units down
Step-by-step explanation:
we have

The vertex of the function h(x) is the point (-3,-5)
we know that the parent function f(x) is equal to

The vertex of the function f(x) is the point (0,0)
so
The rule of the transformation of f(x) to h(x) is equal to
(x,y) -----> (x-3,y-5)
That means ----> The translations is 3 units to the left and 5 units down
Answer:
D
Step-by-step explanation:
that should be the answer
It already shows that AB is 49°
in order to find ABC you must first find BC
360 - (AC + AB) = BC
360 - 156 = BC
204° = BC
NOW add BC with AB
49 + 204
253
angle ABC is 253°
now to find BAC add AB and AC
49 + 107 = 156°
angle BAC is 156°
FINALLY to find ACB add AC and CB
107 + 204
311°
angle ACB is 311°
