-2b +3b = 1b -6+(-2) = 1b -8
Answer:
In bold below.
Step-by-step explanation:
a) Arithmetic sequence with common difference 3 and first term = 2:
nth term = 2 + 3(n - 1)
= 3n -1.
b) Similar to above with common difference 2 and first term = 9.
nth term = 9 + 2(n - 1)
= 2n + 7.
Answer:
The answer is 26.2.
Step-by-step explanation:
To get the answer we take the miles done in the race, in this case 18.34 and he is 70% done the race. To find out how much total miles are in the race, we convert 70% into a decimal which is 0.70. then we have 18.34 and 0.70 to multiply. 18.34 x 0.70=26.2 Which is your answer.
Hope this helps!
