How did you compute sums of dollar amounts that were not whole numbers? For example, how did you compute the sum of$5.89 and$1.4
nignag [31]

Answer:

$7.34

Step-by-step explanation:

To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :

$5.89 + $1.45

Taking the whole numbers first:

$5 + $1 = $6

Take the sum of the decimals :

$0.89 + $0.45 = $1.34

Sum initial whole + whole of sum of decimal

$6 + $1 = $7

Remaining decimal : $1.34 - $1 = $0.34

$7 + $0.34 = $7.34

What is the reason for each step in the solution of the equation? 18−2x=4x
Reika [66]
In order to solve an equation for a certain variable, you should isolate that variable on one side of the equation and leave all the other terms on the other side on the equation.
The, you solve to get the value of the variable.

The equation we have here is:
<span>18−2x=4x
First, we need to isolate the terms containing the "x" on one side of the equation. To do this, we will add 2x to both sides of the equation:
</span><span>18−2x+2x=4x+2x
18 = 6x
Now, we need to get the value of the "x". To do this, we will simply divide both sides of the equation by 6:
18/6 = 6x/6
3 = x .............> This is the solution of the equation</span>

Which is an odd monomial function? A.y=2x^3 B.1/x C.5x^-9 D.3
Anna71 [15]
First let's review two concepts:
 Monomy: Algebraic expression that consists of a single term or in which the terms that form it are related by the product operation.
 Odd function: A function is odd if, for each x in the domain of f, f (- x) = - f (x).
 The function y = 2x ^ 3 complies with both definitions.
 Answer:
 an odd monomial function is:
 
A.y = 2x ^ 3
