Answer: 28 cm
Step-by-step explanation:
x - the length of the shorter piece
2x - the length of the longer piece
Together they are 42 cm long.
Compose te equation:
2x + x = 42
3x = 42
x = 14 cm
The shorter piece is 14 cm, the longer piece is twice longer, 2x, or 2( 14 ).
Two times longer than 14 is 28. The longer piece is 28 cm.
Let a,b & c be the number of cookies Adrian, Bobby and Calvin baked respectively.
(a+b+c)/3 =138
(a+b)/2 =136
a+b=272
a=272-b
(b+c)/2 =125
b+c=250
c=250-b
Sub a=272-b and c=250-b into (a+b+c)/3 =138,
(a+b+c)/3 =138
[(272-b)+b+(250-b)]/3 = 138
272-b+b+250-b = 414
-b = -108
b=108
From the above,
a=272-b
=272-108
a=164
c=250-b
=250-108
c=142
∵ a=164
b=108
c=142
∴ Adrian baked 164 cookies.
Bobby baked 108 cookies.
Calvin baked 142 cookies.
