x = longer section
y = shorter section

x + y = 109
x = 2y + 10

so we sub in eq 2 into eq 1
2y + 10 + y = 109
3y + 10 = 109
3y = 109 - 10
3y = 99
y = 99/3
y = 33 <=== shorter section is 33 cm

x = 2y + 10
x = 2(33) + 10
x = 66 + 10
x = 76 <=== longer section is 76 cm

Fred needs to write the equation of the line. He used (10, 64) and (12.5, 73) to find the slope, which is 3.6. The equation of t

UNO [17]

Answer:

y = 3.6x + 28

Step-by-step explanation:

y = Mx + c

64 = 3.6(10) + c

64 = 36 + c

64 - 36 = c

28 = c
