What is the value of y?
shepuryov [24]
<h3>Answer:   y = 3</h3>

===========================================================

This is because quadrilateral JMQP is also a parallelogram. Note the arrow markers to tell us that JM is parallel to PQ, and also JP is paralle to QM.

A parallelogram has its opposite sides parallel, and those opposite sides are the same length.

JM = PQ and JP = QM

Because y = QM, QM = JP, and JP = 3, this means y = 3.

After five games a football team's goal average is 2.8. After one more game the goal average is 3. The number of goals scored in
Svetlanka [38]

Answer:

4 goals

Step-by-step explanation:

Let:

x = number of total goals scored in first 5 games

y = answer = number of goals in 6th game

formula:

average = sum of individual parts / total number of parts

average_5_games = x / 5 = 2.8

solve for x:

x = 2.8 × 5 = 14

average_6_games = (x + y) / 6 = 3

solve for y:

x + y = 6 × 3 = 18

y = 18 - x = 18 - 14 = 4
