Answer:
Tbh, I think the easiest way is to count on your fingers. I still do it, however I can now do my chart tables to 17x17 by using fingers. People may tease, however, it is a good way to make sure you do not mess up as much as memorizing. You should memorize, and count on your fingers at the same time to solve extremely fast.
Step-by-step explanation:
9x4
You can pretend that your thumb equals nine, and count 9 plus 9 plus 9 plus 9, with each other finger, such as your ring finger, pointer, middle, and pinky , which equals 36. 5x9, you have five fingers on each hand, so each finger can equal nine (I don't care if people say that your thumb isn't a finger, just take it and move on lol).
Answer:
log(18/(p+2))
log StartFraction 18 Over p + 2 EndFraction
Second option is the correct.
Step-by-step explanation:
There is a property of logarithms that when two logarithms are subtracting each other, we can make a single logarithm with the argument being the division of their arguments:
log(x) - log(y) = log(x/y)
So, with we have log18 – log(p + 2), we can rewrite as:
log18 – log(p + 2) = log(18/(p+2)), that is:
log StartFraction 18 Over p + 2 EndFraction
Second option is the correct.
Answer:
6 each
Step-by-step explanation:
Add 1 granola bar $1.15 plus one magazine $1.25 = $2.40
$15.00/$2.40 = 6.25
6 granola bars x $1.15 = $6.90
6 magazines x $1.25 = $7.50
$6.90 + $7.50 = $14.40
The property is distributive property
