Triangular prism !Have a great day !
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:
m = 2
n = -4
Step-by-step explanation:
Using elimination method:
4m + n = 4
m - n = 6
--------------------
5m = 10 // n-n = 0, solve for me
m = 10/5 //divide both sides by 5
m = 2
Pick any only of the equation, replace me with it's value.
m - n = 6
2 - n = 6 //subtract 2 on both sides
-n = 6-2
-n = 4 //Change sign, multiply by -1
n = -4
Solution:
m = 2
n = -4
C. sum of -2. 96 and 4.35
