PEMDAS is important

Parentheses
Exponents
Multiplication
Division
Adding
Subtracting

There's no parentheses or exponents, so the first is multiplication. 9*3 is 27. Next is division, 6/2 is 3. Next is adding.

15+3+27=45

Simplify: 4w(to the power of 9)+(-2w(to the power of 9)) enter the original expression if it cannot be simplified
igomit [66]
4w⁹ -2w⁹
= (4-2)w⁹ . . . . . distributive property, or "collecting terms"
= 2w⁹

_____
In plain text, a caret (^) is used to identify an exponent. w⁹ = w^9. If the exponent has any arithmetic, you need parentheses around it. w^(8+1)

I need some serious help with standard form, Im really confused . Here's a problem ,
OLEGan [10]
I can see that the equation given above is a linear equation since y and x are the only variable and the degree is one. The standard form of a linear equation is written as:

Ax + By = C

We write the given equation into standard form as follows:

<span>y - 2 = 2(x - 3)
</span><span>y - 2 = 2x - 6
y -2x = -6 +2
y - 2x = -4
2x - y = 4</span>

X + 11 &lt; 6 <br> Solve and graph on a number line
Drupady [299]

Answer & Step-by-step explanation:

So I can't exactly graph exactly, but I'll try...

To solve:

x+11<6  Subtract 11 on both sides.

x<-5

To graph:

<-------|---------o---------|-------->

        -6        -5         -4

(The bolded part of the line is the side you shade the graph on. In case you can't see it, you have to shade the left side of the open circle.)

Hope this helps! Have an awesome day ( • ω • )^

In the triangle XYZ the measure of angle YXZ is 50 degrees and the measure of angle XYZ is 75 degrees. What is the measure of an
lbvjy [14]
<h2>Answer: 55 degrees</h2>

Step-by-step explanation:

Every triangle has 3 sides and 3 interior angles whose measures sum to 180 degrees. For example, a triangle with angles \theta, \alpha and \beta:

\theta+\alpha+\beta=180\º

Following this rule, we will apply it to the angles XYZ, YXZ and the unknown XZY:

XYZ+YXZ+XZY=180\º

50\º+75\º+XZY=180\º

XZY=180\º-50\º-75\º

Finally:

XZY=55\º
