Answer:
6
Step-by-step explanation:
since there is a parentheses in-between both subtraction sign it turns into a plus sign which would into the equation 1+5=6
Answer:
1/10 do not exercise at all.
Step-by-step explanation:
That would be 1 - 1/2 - 2/5
= 10/10 - 5/10 - 4/10
= 1/10.
Answer:
see explanation
Step-by-step explanation:
The common difference d of an arithmetic sequence is
d =
-
=
- 
Substitute in values and solve for k, that is
5k - 1 - 2k = 6k + 2 - (5k - 1)
3k - 1 = 6k + 2 - 5k + 1
3k - 1 = k + 3 ( subtract k from both sides )
2k - 1 = 3 ( add 1 to both sides )
2k = 4 ⇒ k = 2
--------------------------------------------------------
The n th term of an arithmetic sequence is
=
+ (n - 1)d
= 2k = 2 × 2 = 4 and
d = 5k - 1 - 2k = 3k - 1 = (3 × 2) - 1 = 5
Hence
= 4 + (7 × 5) = 4 + 35 = 39

Step-by-step explanation:
that options given seem wrong but what do i know thats just difficult dude im just in the 4th grade
A) 90-55=35 since a right angle is 90 total\
