ASHA 777 [7]3 years ago

8 0

Answer:

1. n = 13

2. x = -30

3. y > -18

4. n < -0.75

5. 101 t-shirts

Step-by-step explanation:

1. multiply both sides by 2, then add both sides by 2, making n = 13

2. divide both sides by -3, then subtract both sides by 5 making x = -30

3. divide both sides by -2, when dividing by a negative number, you need to switch the inequality sign to the other side

4. divide both sides by 4, then divide by -2(you need to switch the inequality sign to the other side), then add -8 and 2.5, then add 5.5 to both sides

5. the equation is 150 = 5x - 45. 45 is because they have already earned it, and 5x is how much each shirt will cost. The solution is then 101.

Hope this has a helped a little at least :P

Each question is worth 4 points (100/25=4)
Therefore, when you divide 83 by 4, you get 20.75, as as he's aiming to get a B, this needs to be rounded up to 21.
Xio would need to get 21 questions right to get a B, hope this helps :)

Are these two lines perpendicular?

Answer:

Step-by-step explanation:

This is the image of the graph you determine if that's perpendicular.

Perpendicular definition - In elementary geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle. The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.
