Hello there! :)

Answer:

$\boxed{X=42}$

*The answer must be have A POSITIVE SIGN ONLY!

Step-by-step explanation:

First, you expand.

$4x-(2x-6)=2x+6$

$2x+6=90$

Then, you subtract by 6 from both sides of an equation.

$2x+6-6=90-6$

Subtract by the numbers from left/right.

$90-6=84$

$2x=84$

Divide by 2 from both sides of an equation.

$\frac{2x}{2}=\frac{84}{2}$

Divide by the numbers from left/right.

$84/2=42$

Final answer is → $\boxed{X=42}$

Hope this helps you!

Have a nice day! :)

Answer:

True

Step-by-step explanation:

The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.

Tara has two standard, six-sided dice. If she rolls them 36 times, how many times should she expect a sum less than 5 to show up

andreyandreev [35.5K]

There are six sides on each die. For each possible score on Die 1, there are six possible scores on Die 2. So the number of possible combinations is 6*6 = 36.
It follows that if the dice are thrown 36 times, you would expect each combination to come up once. 

We therefore simply need to know how many combinations add up to less than 5. (I've interpreted this as not including a total of 5 itself). 
These combinations are: 1 and 1, 2 and 1, 1 and 2, 2 and 2, 3 and 1, and 1 and 3 ---> six combinations out of 36. 

So you'd expect a sum less than 5 six times.
