<u>FACTS TO KNOW BEFORE SOLVING :-</u>
- Let x be a number. ⇒ can also be written as .
- To make any variable the subject of any formula , we need to isolate it.
<u>__________________________________________________________</u>
According to the question ,
Lets multiply both the sides by 4.
It can be also written as :-
Lets square both the sides.
Let log5 125 = x
Removing log you get 5^x = 125
Rewrite 125 as 5^3
Now 5^x = 5^3
x = 3
5.7 inches is the correct answer
Answer:
Let the no of quarters be x
According to given,
x + (x+4) + (x+4)/2 = 6
x + (x+4) + (x + 8)/2 = 6
x + x + 4 + (x + 8)/2 = 6
[2 (2x + 4) + (x + 2)]/2 = 6
4x + 8 + x + 2 = 6 × 2
5x + 10 = 12
5x = 12 - 10
5x = 2
x = 2/5
•°• x = 0.4
1 doller = 4 quarter
0.4 doller = p
p = 0.4 × 4 = 1.6
•°• There are 1.6 quarter.
