{x + 4y = 13<br> {x – y = 3
NARA [144]

Answer:

x = 5 and value of y = 2

Step-by-step explanation:

using substitution method

let;

x + 4y = 13...................... equation 1

x - y = 3............................... equation 2

from equation 2

x - y = 3.................................... eqn 2

x = y + 3.......................................... equation 3

put x = y + 3 in equation 1

x + 4y = 13...................... equation 1

y + 3 + 4y = 13

5y = 13 - 3

5y = 10

divide both sides by 5

i.e

5y/5 = 10/5

y = 2

sustitue for y  = 2 in equation 3

x = y + 3.......................................... equation 3

x = 2 + 3

x = 5

therefore the value of x = 5 and value of y = 2

to check if your answwer is correct slot in the value of x and y in any of the equation . e.g

from equation 3

x = y + 3.......................................... equation 3

5= 2 + 3

5 =5....................... proved

What is the probability of rolling a die six times and getting t he number 1,2,3,4,5,6 in that order
anastassius [24]

Answer:

1/46656 I believe. probability isn't really my strong suit tho.

Step-by-step explanation:

1/6 chance for rolling a one × 1/6 chance of rolling a two and so on.

so you get

1/6 × 1/6 × 1/6 × 1/6 × 1/6 × 1/6 = 1/46656
