<h3>
3 Answers: Choice A, Choice B, Choice E</h3>
============================================================
Explanation:
Let's go through each answer choice one by one to see if it's true or false.
- A) This is true. Parallel lines have equal slopes, but different y intercepts.
- B) This is true because of the corresponding angles theorem.
- C) This is false. The statement applies to perpendicular lines, rather than parallel ones.
- D) This is false in general. The only time it's true is when the consecutive interior angles are 90 degrees each. Otherwise, the statement is false.
- E) This is true. Let's say we drew any diagonal line we wanted. Now imagine picking a point on that line and shifting it up 5 units. Do this for another point and draw a line through the two separated points. This forms a parallel line. The upper line has been shifted up 5 units compared to the lower line.
- F) This is false in general. It's only true when both alternate interior angles are 90 degrees each; otherwise, it is false.
Answer:
Sarah bought 30 pencils
Step-by-step explanation:
1. Let define p, as the number of pencils bought, and m, as the number of markers bought.
2.
3. Substitute p in the first equation to 3m since p=3m as defined.
plug m into equation p=3m to find the number of pencils bought

Step-by-step explanation:
Given:
Carlos buys a game for $7.89 and some batteries for $5.49. He pays with a $20 bill.
To find:
The best estimate of the amount of change he should get.
Solution:
First we need to approximate the data values.
Now, the total cost of game and batteries is
He pays with a $20 bill.
Therefore, the estimated amount of change is $6.50.
