in one day a movie store rented out 20 comedies. if the ratio of comedies rented to action movies rented was 4:3, how many action movie were rented ?

Answers

Answer 1

Answer: One way to solve is to set up a proportion. If the ratio of comedies to action is 4:3 (also can be written as the fraction 4/3) then you can set 4/3 equal to 20/x.

4/3 = 20/x

then cross multiply.

4·x = 3·20

4x = 60 Then divide both sides by 4

x= 15

Answer 2

Answer: the answer is 15 action movies were rented

What is the simplest form of the expression (–12.7y – 3.1x) + 5.9y – (4.2y + x)?

Answers

The simplest form of given expression is $-11y-4.1x$ .

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given expression

$(-12.7y-3.1x)+5.9y-(4.2y+x)$

= $-12.7y-3.1x+5.9y-4.2y-x$

Combine like terms

= $(-12.7y+5.9y-4.2y)+(-3.1x-x)$

= $-11y-4.1x$

The simplest form of given expression is $-11y-4.1x$ .

Hint: Subtract 38 from both sides of this inequality. This will simplify the inequality.

Next, divide each side of your resulting inequality by 18. This will produce an inequality of the form "x≤ something."

Answers

The expression for the given statement is g/2h.

The given expression is double h, then divide g by the result.

We need to write an expression for the sequence of operations described in the statement.

What is an expression?

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Now, double h=2h.
