One <em><u>possible answer</u></em> is:
1.2 + 2.3 + 3.4 + 4.1
Explanation:
1.2 + 2.3 = 3.5
3.5 + 3.4 = 6.9
6.9 + 4.1 = 11.0

Answer:
8 Wallets cost 8 * 43 = 344 $
Step-by-step explanation:
The text provides us with the following system:
1. B = 2W + 58
2. 632 = 2B + 8W
Which can be re-evaluated to:
1. B - 2W = 58
2. 2B + 8W = 632
We multiply 1. with 2 and get:
1. 2B - 4W = 116
We then subtract 1. from 2. and get:
12W = 516 --(:12)--> W = 43
We then insert W = 43 into 1.:
B = 2*(43) + 58
--> B = 86 + 58 = 144
3 x 60 (because there are 60 minutes in an hour) = 180. then 180 + 15 = 195. 500 / 195 = 2.6 miles per minute. 2.5 x 60 since its asking for miles per hour, is 156. he goes 156 miles per hour.
Answer:
3225
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= 
[ 2a + (n - 1)d ]
where a is the first term and d the common difference
here a = 6 and
d = 13 - 6 = 20 - 13 = 7, hence
= 
[ (2 × 6) + (29 × 7) ]
= 15(12 + 203) = 15 × 215 = 3225
