Hello!

Significant digits are defined as all digits that determine the value of a number, excluding any zeros that act as placeholders. Let's find the number of significant digits in each option individually:

A. 0.0009462 = 4 significant digits (the zeros are placeholders)
B. 1.000150 = 7 significant digits
C. 2.0145 = 5 significant digits
D. 3.01255 = 6 significant digits

Looking at the list above, we can see that Option B has the greatest number (7) of significant digits.

The answer is Option B.

I hope this helps!

What is the value of y in this system of equations?
mote1985 [20]

Answer:

-21

Step-by-step explanation:

-6x + 2y = -18.........(i)

-3x - 2y = 54...........(ii)

add equ.(ii) to equ. (i)

(-6x + [-3x]) + (2y + [-2y]) = -18 + 54

-9x = 36

x = -4

sub x= -4 into equ (i)

-6(-4) +2y = -18

24 + 2y = -18

24 +18 = -2y

42 = -2y

y = -21
