To find the time in which all the bells ring together, we need to find the LCM of 36,40,48.
Prime factorization of 36=2×2×3×3
Prime factorization of 40=2×2×2×5
Prime factorization of 48=2×2×2×2×3
Hence, LCM of 36,40,48=2×2×2×2×3×3×5=720 seconds.
720seconds=
60
720
minutes=12minutes
Hence, all the bells will ring together after 12 mi
Answer:
-8x + 16
Step-by-step explanation:
This is called expanding brackets in algebra
1. you need to multiply the numeral on outside of the brackets with each of thosse on the inside
-4 x 2x = 8x
-4 x -4 = 16
Answer:
Checked on edg. , the answer is A. Thanks!
Step-by-step explanation:
In this question you need to isolate j. First you multiply 11 on both sides to make 3 + j not a fraction anymore.
3 + j = 22.
Then you isolate j by subtracting 3 on both sides since you must cancel the 3's out to isolate j. Then you get an answer of j = 19
If you miss 9 questions, the how many did you get right?
85 - 9 = 76
So now you got 76 out of 85 correct or 76/85...
Now if you just do the fractional division that is described by the fraction you will get the answer. The fraction bar literally means "divided by", so the fraction means...
76 divided by 85 which equals...
.8941
Now to convert to percentage we multiply by 100 (move the decimal 2 places to the right)
.8941 x 100 = 89.41% Round to nearest one percent...
89%
