Answer:

x = 2 and y = 1

Step-by-step explanation:

A) 5x+y=11

B) x - y = 1.

(Solving by substitution)

B) x - 1 = y

A) 5x + (x -1) = 11. 6x-1=11. 6x = 11+1

6x = 12

x = 12/2. x = 2

B. 2 - 1 = y. y = 1

Answer:

Y=1

Step-by-step explanation:

9y+8y+4Y=5y-16

21y-5y=16

16y=16

Y=16/16

Y=1

So value of Y is 1

If the ending time was 10:35 and 45 minutes passed:

35 - 45 = -10 that does not work. Sooo, what we are going to do is take away 36.

So instead of 10:35, we have 9:59, and instead of 45, we have 9.

59 - 9 = 50

So our answer is: **9:50 was the start time**

**Answer:**

<em>Hello there! Your answer would be </em>**<em> D </em>**<em> and </em>**<em>A </em>**

**Step-by-step explanation:**

<em>I cant see </em><em>**A **</em><em>but as I go through all the others I get </em><em>**A. **</em><em>You know that a rectangle has 4 sides like a quad. but each of the opposite sides has to be equal. So you can see that </em>**<em> D </em>**<em> is without needing to look closer. It gets harder after that. We know that </em>**<em>C </em>**<em>is not one because none of the sides are even. Now there is </em>**<em> B </em>**<em> and </em>**<em> A </em>**<em>if you turn your computer/paper you will see that </em>**<em>B </em>**<em> is a square. So because of that, I think that </em>**<em> A </em>**<em>is a rectangle. :]</em>
