<span>We are going to define two equations where b means bagels and m will be muffins,
First equation: 10*b + 4*m = 13
Second equation: 5*b + 8*m = 14
From the second equation, we can isolate b:
b = (14 - 8*m)/5
In the second equation
10*(14 - 8*m)/5 + 4*m = 13
2*(14 - 8*m) + 4*m = 13
28 - 16*m + 4*m = 13
28 -13 = 16*m - 4*m
15 = 12*m
m = 15/12 = 1.25
Then b = (14 - 8*m)/5 = (14 - 8*1.25)/5 = 4/5 = 0.8
So one bagel costs $0.8 and one muffin $1.25</span>

Answer:
1 7/12
Step-by-step explanation:
Just subtract the fractions if you cant do it by head or paper use a calc so 5 3/4 - 4 1/6= 1 7/12 samuels dad is 1 7/12 taller than samuel.
Answer:
809.4cm²
Step-by-step explanation:
Given the following :
Systematic error = 3.8cm (The measured length is always more than the actual length.)
Most probable dimension :
Width = 85.7 cm
Length = 123.5 cm
Hence most probable area of Rectangle :
Area = Length × Width
Area = 85.7cm × 123.5cm = 10583.95 cm²
Dimension due to Systematic error :
Length = (85.7cm + 3.8cm) = 89.5cm
Width = (123.5cm + 3.8cm) = 127.3cm
Area = Length × width
Area = ( 89.5cm × 127.3) = 11393.35cm²
Systematic error of the area :
value of area with Systematic error - Probable value of area :
11393.35cm² - 10583.95 cm² = 809.4cm²
