Subtract 2F2Csixteen -92sixteen =
UkoKoshka [18]
Choice-'B' is the correct choice . . . 2E9A .

I began converting the original numbers to decimal (base 10),
but decided that 5 points are not worth that much aggravation.

At that point, I wondered whether I could just write it down and
do it like any old other subtraction exercise.  I've never done
that before with hex numbers, but I found that I could ! 

The only place you have to be extra careful is in the third place,
where you have to subtract '9' from '2'.  In order to do that, you
have to borrow one from the 'F'.  That makes the 'F' an 'E', and
it makes the '2' an '18', from which you can then easily subtract
the '9'.  The difference of '2E9A' then jumps right out.

Thank you.  I never knew you could just do that.

What is the solution to the system of equations?
White raven [17]
Equation A find “m” and “b”:
“B” is the y-intercept when x = 0. They give this in the table as “-2” so b = -2
Find slope (m) = (-8)-(-2)/(-2)-0 = 3
Equation A is y = 3x - 2 (y = mx + b)
Equation B find “m” and “b”:
Find m = (-9)-(-5)/(-3)-(-1) = 2
To find be, plug in m, x, and y from ANY coordinates in table b into y = mx + b:
-9 = 2(-3) + b
-9 = -6 + b
b = -3
Equation b is y = 2x -3
Use substitution and substitute all of equation “b” for “y” in equation a:
2x - 3 = 3x - 2
Algebra: x = -1
Plug back into equation a:
y = 3(-1) -2
y = -5
x = -1
(-1, -5) final answer (B)

Answer:

Step-by-step explanation:

a)

 428721

Place of 2's 10s and 10,000s

Therefore its value is 20 and 20,000

Product of the place value = 20 x 20,000 = 4,00,000

b)

37,20,861

Place of 7 is 1,00,000

Therefore the place value is 7,00,000

c)

Greatest 7 digit number is 99,99,999

Adding 1 to it = 99,99,999 + 1 = 1,00,00,000
