Log 10 100 =2
Basically, we have to know how to solve for x in this equation:
10^x = 100
For log3 = 9 we have to solve for x in this equation:
3^x = 9
Therefore, x = 2
3x - 15 < 4x - 2
3x - 4x < -2 + 15
-x < 13
x > -13
I think it is
1: 72
because there are 12 inches in a foot, and the room is 12 feet wide. 12 feet is 144 inches ( 12 x 12), and in the drawing, the width is 2 inches.
So, it went from its original 144 inches to 2 inches. I think it can also be written as 1: 72 because 1 is it's original from, and it became 72 times smaller.
The answer is B
4(4+10)
4*4=16
4*10=40 which will give you (16+40)
Answer:
The cost of coat without sales tax is $ 80 .
Step-by-step explanation:
Given as :
The cost of coat with sales tax = $ 86.40
The rate of sales tax = 8 %
Let The cost of coat without sales tax = $ c
So, c + 8% of c = $ 86.40
Or, 1.08 of c = $ 86.40
Or, c = 
∴ c = $ 80
Hence The cost of coat without sales tax is $ 80 . Answer
