Answer:
11th term is 0
Step-by-step explanation:
30, 27 , 24 ,......0
a = first term = 30
Common difference = second term - first term = 27 - 30 = -3
nth term = a+(n-1)*d
a + (n-1)d = 0
30 + (n - 1) *(-3) = 0
30 + n*(-3) -1*(-3) = 0
30 - 3n + 3 = 0
-3n + 33 = 0
-3n = -33
n = -33/-3
n = 11
Answer:
Step-by-step explanation:
first subtract 125-180=X you will get X=55 so then add X+X+y=180 which x+x+y= is actually 55+55+y=180 but don't add the y just yet add 55+55 then you will get 110+y=180 so then flip it backwards and do y=180-110 and your anwser is y=70
Answer:
-2 and 3
Step-by-step explanation:
These two are slopes. All three are technically slopes but a slope of 0 is just a horizontal line.
