This rational expression is nonequivalent. 5x / 25x^4 ; x^3 / 5x^15<br> True or false?????
FromTheMoon [43]

It is nonequivalent. Figure it out this way. Think about what number has to be multiplied by both the numerator and the denominator of \frac{5x}{25x^4} to get to \frac{x^3}{5x^15}. It has to be the samee number for the one expression to be equivalent to the other. To get from 5x to x^3, we have to multiply by 1/5x^2. When we do that we get x^3. Good. Now we have to multiply the denominator by the same thing, 1/5x^2. 25x^4(\frac{1}{5}x^2)=5x^6. As you can see, they are not equivalent.

Mia is ordering 5 identical sandwiches and a bag of chips. The bag of chips costs $1.25, and the entire order costs $38.75. Writ
Greeley [361]

Answer:

The equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75

Step-by-step explanation:

The equation that can be use to determine the price of a sandwich is as follows:

Let us assume the price of a sandwich be x

So,

The equation would be

5x + $1.25 = $38.75

5x = $38.75 - $1.25

x = $37.5 ÷ 5

x = $7.5

hence, the equation that can be use to determine the price of a sandwich is 5x + $1.25 = $38.75

Use the following triangle to answer the following questions. You may use some answers more than once.
marta [7]

First, find the length of the hypotenuse using the Pythagorean theorem: a^2+b^2=c^2

25 + 144 = c^2

\sqrt{169} = c^2

13 = c

Now, find each of the values! Sin = opposite/hypotenuse; Cos = Adjacent/hypotenuse; Tan = Opposite/Adjacent.

1. A

2. A

3. C

4. B
