Step-by-step explanation:
diameter of an average cell= 1 x 10^-5 mm
diameter of a pin head= 2 x 10^-2
number of body cells that would fit on the pin head=2 x 10^-2 ÷ 1 x 10^-5
=2000 body cells
Answer:
x = 2, y = 7, z = 12
Step-by-step explanation:
x + y - z = -3 (1)
3x - y + z = 11 (2)
x - 4y + z = -14 (3)
add (1) and (2)
4x = 8 x = 2
add (1) and (3)
2x - 3y = -17
2(2) - 3y = -17
-3y = -17 - 4
-3y = -21
y = 7
Find z using any equation
x + y - z = -3
2 + 7 - z = -3
9 - z = -3
z = 12
Answer:
Your answer is D
