The answer is A. h + 3s = 35 and 2h + s = 20
Answer: For example if it is a number such as 45,212 and you are dividing it by 20. Ignore the 212 until you get rid of the 45 then go from there.
Answer:
she worked for 4.5 hours
Step-by-step explanation:
she gets 10 an hour
45/10=4.5
You can treat it as an arithmetic sequence, so multiply the average integer value by the number of integers:
(40+12)/2 × (40 -12 +1) = 26×29 =
754You can subtract the sum of integers 1–11 (66) from the sum of integers 1–40 (820) to get the sum of integers from 12–40: 820 - 66 =
754.
You can let a graphing calculator do it. (See attached.) This method takes perhaps the least amount of thought. It, too, gets a sum of
754.
That would be 49 because AB is basically LM and AC is basically LN. Also 5 (AB) times 7 equals 35 (LM), which means 7 (AC) times 7 equals 49 (LN) which is LN. Hope I helped!!
