Answer:

3, 18

Step-by-step explanation:

To write an equation or an expression, define the variables.

x is the first number.

6x is the second number since it is 6 times the first.

Add the expressions together to 21 to solve.

x + 6x = 21

7x = 21

x=3

The first number is 3. The second is 6*3 = 18.

monarch butterflies migrates when they sense daylight hours are shorter and temperature get colder.write two equivalent fraction
Tpy6a [65]

Two equivalent fractions to represent the part of the migration a monarch butterfly can complete in 1 week is \frac{5}{25} or \frac{1}{5}.

<h3>What is a fraction?</h3>

A fraction is a mathematical expression that shows the relationship between parts vs total. In a fraction, the part is written first and it is known as the numerator. On the other hand, the total is written below and it is known as the denominator.

<h3>How to write a fraction?</h3>

Here are the steps to write a fraction:

  • Find the total.
  • Find the part.
  • Write the fraction.

Based on this, in the chart, the part of the migration these butterflies can complete in a week are the squares in green, while the total is the total squares. This means the fraction for this situation is:

  • \frac{5}{25}

Moreover, you can simplify this fraction and find an equivalent one by dividing the denominator by the numerator as:

  • \frac{1}{5}

AVprozaik [17]

The triangle pairs that can be mapped to each other using a reflection and a translation is; Option B

<h3>How to Interpret Triangle Transformations?</h3>

Let us analyze each of the graphs;

Option A; This graph didn't use a reflection and a translation because we see that there was first a reflection across side QR and then another reflection across side AR.

Option B; This graph is correct as it made use of a reflection and a translation as seen in the attached graph.

Option C; This didn't use of a reflection and a translation because it instead carried out translation both in vertical and horizontal direction.

Option D; This carried out Translation and Rotation.
