What is the 6th term of an arithmetic sequence with a9 = 120 and a14 = 195?

Step-by-step explanation:

a9 = 120 > a + 8d = 120

a14 = 195 ---> a + 13d = 195

subtract them

5d = 75

d = 15

then a+8(15) = 120

a = 0

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
