<span>For three numbers to represent lengths of the sides of a triangle, the sum of each pair must be greater than the remaining side.

A)
3 + 4 = 7
3 + 5 = 8
5 + 4 = 9

B)
2 + 5 = 7
2 + 8 = 10
5 + 8 = 13

C)
2 + 12 = 14
2 + 15 = 17
15 + 12 = 27

D)
3 + 3 = 6
3 + 7 = 10
3 + 7 = 10

In all these, only A have the sum of the numbers greater than the numbers itself. So the answer is A.

We know that

x = $\sqrt{\frac{4}{16}}$

So:

For the following system, if you isolated x in the first equation to use the substitution method, what expression would you subs

alekssr [168]

Answer:

$x=2y+6$

Step-by-step explanation:

So we have the system:

$-x+2y=-6\\3x+y=8$

If we isolate the x-variable in the first equation:

$-x+2y=-6$

Subtract 2y from both sides:

$-x=-6-2y$

Divide both sides by -1:

$x=2y+6$

Therefore, we would substitute the above into the second equation:

$3x+y=8\\3(2y+6)+y=8$

The answer is 2y+6

Further notes:

To solve for the system, distribute:

$6y+18+y=8$

Simplify:

$7y+18=8$

Subtract:

$7y=-10$

Divide:

$y=-10/7\approx-1.4286$

Now, substitute this value back into the isolated equation:

$x=2(-10/7)+6\\x=-20/7+42/7\\x=22/7\approx3.1429$
