Simplify each only using positive exponents:<br> 2x^-3 • 4x^2<br> 2x^4 • 4x^-3<br> 2x^3y^-3 • 2x
erica [24]
<h2>Answer:</h2>

\frac{2}{x}

\frac{x}{2}

\frac{4x^4}{y^3}

<h2>Step-by-step explanation:</h2>

a. 2x^-3 • 4x^2

To solve this using only positive exponents, follow these steps:

i. Rewrite the expression in a clearer form

2x⁻³ . 4x²

ii. The position of the term with negative exponent is changed from denominator to numerator or numerator to denominator depending on its initial position. If it is at the numerator, it is moved to the denominator. If otherwise it is at the denominator, it is moved to the numerator. When this is done, the negative exponent is changed to positive.

In our case, the first term has a negative exponent and it is at the numerator. We therefore move it to the denominator and change the negative exponent to  positive as follows;

\frac{1}{2x^3} . 4x^2

iii. We then solve the result as follows;

\frac{1}{2x^3} . 4x^2 = \frac{2}{x}

Therefore, 2x⁻³ . 4x² = \frac{2}{x}

b. 2x^4 • 4x^-3

i. Rewrite as follows;

2x⁴ . 4x⁻³

ii. The second term has a negative exponent, therefore swap its position and change the negative exponent to a positive one.

2x^4 . \frac{1}{4x^3}

iii. Now solve by cancelling out common terms in the numerator and denominator. So we have;

\frac{x}{2}

Therefore, 2x⁴ . 4x⁻³ = \frac{x}{2}

c. 2x^3y^-3 • 2x

i. Rewrite as follows;

2x³y⁻³ . 2x

ii. Change position of terms with negative exponents;

2x^3.\frac{1}{y^3} .2x

iii. Now solve;

\frac{4x^4}{y^3}

Therefore, 2x³y⁻³ . 2x = \frac{4x^4}{y^3}

Using faucet P, you can fill a sink in 10 minutes. Faucet Q takes only 8 minutes to fill the same sink. How long will it take to
nevsk [136]

It would take 4.44 minutes to fill the sink using both faucets P and faucet Q together

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

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

Let t represent the time it takes to fill the sink using both faucets together, hence:

(1/10 + 1/8)t = 1

t = 4.44 minutes

It would take 4.44 minutes to fill the sink using both faucets P and faucet Q together

In their first 5 games last year, the Dallas Cowboys scored 35, 31, 31, 10, and 24 points. How many points did the Cowboys avera
Anna71 [15]

Answer:

26.2 points

Step-by-step explanation:

To find the average, find their total number of points and divide by the number of games

total points/number of games

To find their total points, add all their points together

35+31+31+10+24=131

Then, divide by the number of games (5)

131/5=26.2

So, they scored an average of 26.2 points

Hope this helps! :)
