Answer:
-0.523
Step-by-step explanation:
log(a/b)=loga-logb
log (0.3) can be written as log (3/10).
=log(3/10)
=log3-log10
=0.477-1 (log3=0.477 and log10=1)
= -0.523
Answer:
x=12
Step-by-step explanation:
The two angles are equal to 180 degrees, we already know that one angle is 110, so we find the difference.
180-110=70
4x+22=70
70-22=48
48/4=12

1. the sum of its integers can be divided by 3
2. The number is even (ending in 0, 2, 4, 6, 8
With this rule in mind, you have to play around with the numbers. Of course, all odd numbers are out.
606:
6 is even
6 + 6 = 12
12 divided by 4 is 3
612:
2 is even
6 + 1 + 2= 9
9 divided by 3 is 3
