Based on the shipping rate and the price of the t-shirts, it can be concluded Sam ordered a total of 6 t-shirts.

<h3>What equation represents Sam's situation?</h3>

5.99 + x12.50 = 80.99

x represents the number of t-shirts she bough, which is the focus of the equation.

Let's solve it:

  • 5.99 + x12.50 = 80.99
  • x12.50 = 80.99 - 5.99
  • x12.50 = 75
  • x = 75 / 12.50
  • x = 6

<h3>How many t-shirts did Sam order?</h3>

Sam ordered 6 t-shirts.

Lines l and m are parallel because same-side interior angles are supplementary

From the question, we are to determine the lines we can conclude are parallel

From the given information, we have that

m ∠3 + m ∠4 = 180°

That is,

The measure of angle 3 and the measure of angle 4 are supplementary.

In the diagram,

We can observe that ∠3 and ∠4 are same-side interior angles

NOTE: If interior angles on the same side of the transversal sum to 180, then lines are parallel.

Hence,

Due to the fact that same-side interior angles are supplementary, lines l and m are parallel

What is 72 + 4x = 2x + 82
yarga [219]
The answer is X = 5 because first you have to take away 2x from that side so u minus 2x from 4x that gives u: 72 + 2x = 82 then you have to minus 72 from both sides and that gives you 2x = 10 once you have that you divide both sides by 2 because you want the X by itself and once you get that X = 5. Hope this helped!
