Answer:

$x=-1\text{ or }x=11$

Step-by-step explanation:

For $a=|b|$ , we have two cases:

$\begin{cases}a=b,\\a=-b\end{cases}$

Therefore, for $18=|15-3x|$ , we have the following cases:

$\begin{cases}18=15-3x,\\18=-(15-3x)\end{cases}$

Solving, we have:

$\begin{cases}18=15-3x, -3x=3, x=\boxed{-1},\\18=-(15-3x), 18=-15+3x, 33=3x, x=\boxed{11}\end{cases}$ .

Therefore,

$\implies \boxed{x=-1\text{ or }x=11}$

Please help!!! The sum of three consecutive integers is 9.

Travka [436]

Answer:

Step-by-step explanation:

because they're consecutive, each integer has to come right after the one before it.

if 1st integer is 1, the 2nd should be 2, and the 3rd should be 3.

3 is equal to 1 + 2, or n + 2

hopefully that works

What is the value of x? 5 sqrt 2 10 sqrt 2 5 10

vitfil [10]

Hey there! :D

So, basically, you could say that "x" is equal to both of the legs.

We also know that in 45-45-90 triangles, x*√2= the hypotenuse

Given this information, if we were to divide 10 by the √2, we would get:

10/√2= 7.071.....

5√2= 7.071....

5√2 is the answer.

I hope this helps!
