Answer:
the mean is 85
the range is 98-62=36
the median is 90
the mode is 94
Step-by-step explanation:
X + y = 47
x = y + 13
y + 13 + y = 47
2y + 13 = 47
2y = 47 - 13
2y = 34
y = 34/2
y = 17
x = y + 13
x = 17 + 13
x = 30.....longer piece is 30 inches
(4x - 8) = 80/2
4x - 8 = 40
4x = 48
x = 12
answer
x = 12
