Answer:
answer is 15.40 because 9 is greater than 5 so 1 is carry over it .So answer is 15.40
Step-by-step explanation:
from,
An = 4n -13
A1 = 4 (1) - 13
> A1 = -9
A2 = 4(2) - 13
> A2 = -5
A3 = 4(3) - 13
> A3 = -1
A4 = 4(4) - 13
> A4 = 3
9 - 2(x + 6) =
9 - 2x - 12 =
-2x - 3 <=
3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
Answer:
It a simultaneous equation so the solution is 2
