ANSWER

$ax-by=k$ is an example of literal equation.

EXPLANATION

A literal equation is an equation in which letters or variables are used to represent real values.

A literal equation consists of at least two letters or variables.

The first option consists of two variables but it is not an equation. It is just an expression.

The second option is not a literal equation because it consists of only one variable. This is just a linear equation in one variable. But a literal equation should have at least two variables or letters.

As for the third option, it does not even contain a variable or letter.

Choice D. represents a literal equation

Jabari owns 100 shares of Stock A and 45 shares of Stock B. For the past month, his stocks have been fluctuating inversely each week. Stock A decreased by m cents per share and Stock B increased by n cents per share. Which equation can be used to find the total change in value of Jabari's shares?

Answers

This is how we solved and make the equation.
Stock A = 100
Stock B = 45

For the past months, his stocks inversely decreased.
Stock A = m cents / share
Stock B = n cents * share

So the equation is
= 100 (0.01m) + 45 (0.01n)
= m + 0.45n

a fraction is such that the numerator is 2 less than the denominator if you add 3 to the numerator and 5 to the denominator the resulting fraction is 3/5 find the fraction

Answers

Answer: 3/5

Step-by-Step Explanation:

Let x represent the denominator of the fraction, then we have $(x-2)/(x)$

Now add 3 to the numerator and 5 to the denominator and set it equal to 3/5:

$((x-2)+3)/((x)+5)=(3)/(5)\n\n\n\text{Simplify:}\n(x+1)/(x+5)=(3)/(5)\n\n\n\text{Cross Multiply and solve for x:}\n5(x+1)=3(x+5)\n5x+5=3x+15\n2x=10\nx=5$

Substitute x = 5 into the original fraction:

$((5)-2)/((5))\quad =\large\boxed{(3)/(5)}$

Answer:

The required fraction is 3/5
