Answer:

x = 1 (Option C)

Step-by-step explanation:

3x - 4y = -5 (1)

-3x - 4y = -11 (2)

On adding

3x - 4y - 3x - 4y = -11 + 5

6x = 6

x = 6/6

x = 1

Elimination method is a method of eliminating one of the variables from the two equations whose remaining variables will be simplified..

3x - 4y= -5 (×1) 3x - 4y= -5

-3x - 4y= -11 (×1) -3x - 4y = -11 (-)

6x = 6

6x/6 = 6/6

x = 1

the value of x is 1

-7 - (-31) = 24

Now find 1/8 of that distance: 1/8 • 24 = 3

Now move 3 units from -31 towards -7: -31 + 3 = -28

assume that 2000 births are randomly selected and 64 of the births are girls. use subjective judgment to describe the number of

tatuchka [14]

Total no. of births = 2000

Births of girls = 64

Birth% of girls

$= \frac{64}{2000} \times 100$

$= \frac{64}{20}$

$= \frac{6.4}{2}$

$= 3.2\%$

Hence, the number of girls are significantly low.
