To solve the linear equation , the first step is to multiply each side by the least common denominator of all the fractions in the equation. What is the LCD?

84

Step-by-step explanation:

The least common denominator of the 7, 6, 12, which are the denominators of the fractions in the given linear equation, is the least expression or number that is divisible by 7, 6, 12.

To find the LCD, express each number as factors of itself as follows:

Find the product of the highest terms

The product = LCD =

LCD of 7, 6, 12 = 84

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
