Billy has a die. He rolls the die, and if the result is not even, he rolls the die

PIT_PIT [208]

Answer:

1/4 is the answer.

Step-by-step explanation:

If he has a die then it is 6 sided. He has a 1/2 chance the 1st time that he gets a non-even number. The next time he also has a 1/2 chance of getting an even number so it's 1/2 times 1/2 = 1/4.

Using substitution to solve the system below, what expression should be substituted into the first equation? 2x-4y=-4 and x+2y=8

inna [77]

Answer:

Given the system of equation:

$2x-4y=-4$ ......[1]

$x+2y=8$ ......[2]

we can rewrite equation [2] as;

$x = 8-2y$ ......[3]

Substitute equation [3] into [1] to eliminate x, and solve for y;

$2(8-2y)-4y = -4$

Using distributive property: $a\cdot (b+c) = a\cdot b+ a\cdot c$

$16-4y -4y = -4$

Combine like terms;

16 - 8y = -4

Add 4 to both sides we have;

20 - 8y = 0

Add 8y to both sides we have;

20 = 8y

Divide 8 to both sides we have;

$y = 2.5$

Substitute the y-value in [3] we have;

$x = 8-2(2.5)$

x = 8 - 5 = 3

Therefore, the expression should be substituted into the first equation is, $x = 8-2y$ and also the value of x = 3 and y = 2.5
