I attached the picture associated with this question.

Answer:
x = 2
y = 5

Explanation:
ABCD is a parallelogram. This means that each two opposite sides are equal.
This means that:
1- AB = CD
2y + 1 = 7x - 3 ...........> equation I
2- AD = BC
3x = y + 1
This can be rewritten as:
y = 3x - 1............> equation II

Substitute with equation II in equation I and solve for x as follows:
2y + 1 = 7x - 3 ...........> equation I
2(3x - 1) + 1 = 7x - 3
6x - 2 + 1 = 7x - 3
6x - 1 = 7x - 3
7x - 6x = -1 + 3
x = 2

Substitute with x in equation I to get y as follows:
y = 3x - 1
y = 3(2) - 1
y = 6 - 1
y = 5

Hope this helps :)

Kira ran 8 1/5 miles in 69 7/10 minutes. What is Kira’s average time per mile?
Setler79 [48]

Answer:

1 mile = 8.5 minutes

Step-by-step explanation:

<u>Determining the equation:</u>

Kira ran 8 1/5 miles in 69 7/10 minutes.

⇒ Kira = 8 1/5 miles = 69 7/10 minutes

⇒ 41/5 miles = 697/10 minutes

<u>Simplifying both sides:</u>

⇒ 41/5 miles = 697/10 minutes

⇒ 41 miles = 697/2 minutes

<u>Using cross multiplication:</u>

⇒ 41 × 2 miles = 697 minutes

⇒ 82 miles = 697 minutes

<u>Dividing 82 both sides:</u>

⇒ 82 miles = 697 minutes

⇒ 82/82 miles = 697/82 minutes

⇒ 1 mile = 8.5 minutes
