10⁻³ * 10 * 10^(k) = 10⁻³

10 ⁻³ ⁺ ¹ ⁺ $^{k}$ = <span>10⁻³

</span>10 ⁻² ⁺ $^{k}$ = <span>10⁻³
</span>
Since the bases are the same, we can compare the powers.

-2 + k = -3

k = -3 + 2

k = 2 - 3

k = -1

Explain how you can use division to simplify a complex fraction.

PolarNik [594]

Reduce the final answer if needed (or reduce when you multiply). A mixed number should be converted to an improper fraction (heavier on top) before simplifying. Change the numerator and denominator to single fractions<span> by creating a common denominator</span>

A bag contains 8 red marbles, 6 white marbles, and 6 blue marbles. find P (red or blue)

vlabodo [156]

I'm assuming you're supposed to find the chance of them drawing red or blue/
So the whole is 20, and red and blue combined is 14.So its 14/20, which is 70%, and as a simplified fraction it is 7/10.

Write an algebraic expression to represent each statement<br> 50 added to half of a number, c

Fittoniya [83]

The expression represented by 50 added to half of a number, c is 50 + c/2

<h3>What are expressions?</h3>

Expressions are mathematical statements that are represented by variables, coefficients and operators

<h3>How to translate the algebraic expression?</h3>

The expression is given as

50 added to half of a number, c

half of a number, c means divide c by 2

So, we have

50 added to half of a number, c => 50 added to c/2

Added to means +

So, we have

50 added to half of a number, c => 50 + c/2

Hence, the expression represented by the statement is 50 + c/2
