Well u have to make the denominator the same so u multiply 3/8 by 3 and get 9/24, then multiple 2/6 by three and get 8/24. Add them, 9/24+8/24 and u get 17/24
Answer:
24 cm
Step-by-step explanation:
You multiply the meters You have by 100 so for example 0.24 X 100 = 24
so your answer should be 24 cm let me know if I'm wrong
1/2 because 2/4 is just half of 4/5
Answer:
C D and E
Step-by-step explanation:
The only one you probably can never do is B. It get's you no where. The way A is written, it is not much help to write 18 in base 2. So A and B both won't work. The common logs and the natural logs will both work
Log(4^(x + 3)) = Log(18)
(x + 3) Log(4) = log (18)
(x + 3) * 0.6021 = 1.2553
x + 3 = 1.2553/0.6021
x + 3 = 2.08496
Now all you need do is subtract 3 from both sides. The natural logs will give you the same answer.
You could take base-4 logs of both sides and it is a possible first step, but d and e are much more efficient. You have to change both sides to base 4 before you can proceed. This one is kind of iffy. It does say possible first steps.
