Answer:

1/2

Step-by-step explanation:

2x - 5y

2(2/3) - 5(1/4)

(2/1 x 2/3) - (5/1 x 1/4)

(4/3) - (5/4)

(4/3 x 4/4) - (5/4 x 3/3)

HELP ME PLEASE MY LAST DAY TO TURN THIS IN! MARKING BRAINLIEST
Mariana [72]
Solve the following system by Elimination:
{7 x + 3 y = 22 | (equation 1)
{4 y = 20 | (equation 2)

Divide equation 2 by 4:
{7 x + 3 y = 22 | (equation 1)
{0 x+y = 5 | (equation 2)

Subtract 3 × (equation 2) from equation 1:
{7 x+0 y = 7 | (equation 1)
{0 x+y = 5 | (equation 2)

Divide equation 1 by 7:
{x+0 y = 1 | (equation 1)
{0 x+y = 5 | (equation 2)

Collect results:

Answer: {x = 1, y = 5

_____________________________________________________

Solve the following system:
{y - 2 x = 10 | (equation 1)
{4 x - y = -14 | (equation 2)

Swap equation 1 with equation 2:
{4 x - y = -14 | (equation 1)
{-(2 x) + y = 10 | (equation 2)

Add 1/2 × (equation 1) to equation 2:
{4 x - y = -14 | (equation 1)
{0 x+y/2 = 3 | (equation 2)

Multiply equation 2 by 2:
{4 x - y = -14 | (equation 1)
{0 x+y = 6 | (equation 2)

Add equation 2 to equation 1:
{4 x+0 y = -8 | (equation 1)
{0 x+y = 6 | (equation 2)

Divide equation 1 by 4:
{x+0 y = -2 | (equation 1)
{0 x+y = 6 | (equation 2)

Collect results:

Answer:  {x = -2, y = 6

the length of the a human hair= 8.4 x 10^-5

length of the vicuna hair:0.000006 = 0.6 x 10^-5

===========================================

difference between human hair and vicuna hair:

8.4 x 10^-5 - 0.6 x 10^-5 = 10^-5 ( 8.4 - 0.6)

= 10^-5 (7.8)

= 7.8 x 10 ^-5 meters
