1 foot = 12 inches.
Divide total inches by 12:
51 / 12 = 4.25 feet.
The whole number is the number of feet. Now multiply the decimal portion by 12 to get inches:
0.25 x 12 = 3 inches
51 inches = 4 feet 3 inches
The student is 4 feet 3 inches tall
Answer:
Step-by-step explanation:
the 2nd choice looks good Emily
y > x
y > x+2
The straight line is given by the equation
y=kx+b
We substitute coordinates of points
-21=-66k+b (1)
2=-67k+b (2)
We give a system of equations
Solution of this system:
(1) b=66k-21
(2) 20=-67k+66k-21
20=-k-21
k=-21-20
k=-41
b=-41*66-21=-2727
y=-41x-2727
