Answer:
= 10 - 3n
Step-by-step explanation:
the terms 7, 4, 1, - 2 form an arithmetic sequence with n th term
=
+ (n - 1)d
where d is the common difference and
the first term
here d = - 2 - 1 = 1 - 4 = 4 - 7 = - 3 and
= 7, hence
= 7 - 3(n - 1) = 7 - 3n + 3 = 10 - 3n
To find the answer, you must first turn the fractions into decimals. 4 ÷ 5 = 0.8 ; 1 ÷ 2 = 0.5 ; 1 ÷ 10 = 0.1. Then you must subtract 0.5 from 0.8. Then add 0.1 to 0.3 .
Step-by-step explanation:
90-2x + 3x + 60 = 180
90 + x + 60 = 180
x + 150 = 180
x = 30°
