.21 is decimal form, 21/100 is the fraction in simplest form.
The length of line in green = 5 cm
the length of line in yellow = 3 cm
the length of line in red = 6 cm
the length of line in white = 16 cm
the total area = 100 + 12 + 12 + 20 + 24 + 96 = 264 cm2
This is pretty simple once you get used to this
First set it equal to the original and the negative one
(>_) is the bigger and equal to part
4x+5>_45 or 4x+5>_-45
Then solve for x for both
4x>_40. 4x>_-50
X>_10 X>_-25/2
Answer:
y=3x+7
Step-by-step explanation:
Where y is the dependent variable and x is the independent variable. When we change x , Y also changes.
20 meter per second= 1200 m/h=1.5km/h
The time is 1300: 1.5 =866.66
