Answer:
There are 77 more third graders than second graders.
Step-by-step explanation:
415-338=x
x=77
A) x • 3 + 4 = 22
b) 22-4= 18
so since 18 is left, what times 3 = 18? thats 6. so
6 x 3 + 4 = 22
we can check.
18 + 4 = 22
it equals 22 so thats your answer. x = 6. hopes this helps
Answer:
b = 
Step-by-step explanation:
Using the rule of logarithms
log 
⇔ nlogx
Given
190 = 
( take the natural log ln of both sides )
ln190 = ln = bln200 ( divide both sides by ln200 )
= b
