Double the quotient of 3 and 6​
Hitman42 [59]

\huge{\boxed{1}}

This statement can be represented as 2*\frac{3}{6}, since the quotient is the answer to a division problem.

Divide. 2*\frac{1}{2}

Multiply. 2*\frac{1}{2}=\frac{2}{1}*\frac{1}{2}=\frac{2*1}{1*2}=\frac{2}{2}

Simplify.  When the numerator and denominator are the same, the fraction is equal to 1. \frac{2}{2}=1

Mrrafil [7]

Ralph chase invested $85000 at an interest of 10% and $70000 at an interest of 8%

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Let a represent the amount invested at interest of 10% and b represent the amount invested at 8%, hence:

a + b = 155000    (1)

Also:

0.1a + 0.08b = 14100    (2)

From both equations:

a = 85000, b = 70000

Ralph chase invested $85000 at an interest of 10% and $70000 at an interest of 8%
