Answer:

2x-4 = 22

2x = 26

x=13 check |26-4|=22

-(2x-4) = 22

-2x+4 = 22

-2x = 18

x=-9 Check |-18 -4| = |-22| = 22

Answer:

x=13

Step-by-step explanation:

Finding the answer to this is very simple actually. you can actually solve this problem without the || because x has to be a positive value for this to work. 2x-4=22 can be done by adding 4 to both sides and getting the answer 26. Isolate the variable by dividing both sides by 2 to get x=13

Solve the equation 58 - 10x ≤ 20 + 9x

drek231 [11]

Answer:

x≥2

Step-by-step explanation:

First, write out the equation as you have it:

$58-10x\leq20+9x$

Then, add $10x$ to both sides:

$58-10x+10x\leq20+9x+10x\\58\leq20+19x$

Next, subtract $20$ from both sides:

$58-20\leq20-20+19x\\38\leq19x$

Finally, divide both sides by $19$ :

$\frac{38}{19}\leq\frac{19x}{19}\\2\leq x$

$x\geq 2$

Therefore: the answer to this inequality/equation is: x≥2

Answer:

-1/240 (Might be wrong though)

Step-by-step explanation:

The first thing we need to do is multiply 1/15 and 1/16 because product means the answer to a multiplication equation.

1/15 times 1/16 = (1*1)/(15*16) = 1/240

Now that we know the product 1/240, we just have to find the opposite, which is -1/240 because you just add a negative sign in opposites( even in negative numbers)

Interior and Exterior Triangle Angles<br><br> please help asap !!!!

Fiesta28 [93]

Answer:

∠ WUV = 36°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ VWX is an exterior angle of the triangle, thus

8x - 18 = 2x + 8 + 3x + 16

8x - 18 = 5x + 24 ( subtract 5x from both sides )

3x - 18 = 24 ( add 18 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Thus

∠ WUV = 2x + 8 = 2(14) + 8 = 28 + 8 = 36°
