-m + 6 = 3m + 14

m = -2

Step-by-step explanation:

Hi! This answer may seem too big, but I suggest taking the time to read it as it will help you a lot in the future.

Step 1:

Let's start by multiplying -(m - 6).

Essentially, you are turning the expression (m - 6) negative or multiplying the expression (m - 6) by -1

This uses the distributive property of multiplication (distributing the outside factor to all the terms inside the parenthesis. You'll see how it works soon.)

Let's solve:

-(m - 6)-1(m - 6)-1(m) - 1(-6)PAUSE

Here are a couple of tips:

Tips:A positive number times a negative number is always a negative numberA positive number times a positive number is always a positive numberA negative number times a negative number is always a positive numberA number times 1 is the same numberA number times -1 is the opposite of that number

So basically, if you are multiplying terms with the same sign (positive or negative), it is always positive. Numbers with opposite signs are always negative.

CONTINUE

Using the information we have now, we can multiply the terms

-1(m) - 1(-6)-m + 66 - m

The left-hand side of the equation becomes 6 - m

Step 2:

Now, let's solve for m.

Solve for m:

Tips:When dividing a positive number by a negative number, the answer is always negativeWhen dividing a negative number by a positive number, the answer is always negativeWhen dividing a positive number by a positive. number, the answer is always positiveWhen dividing a negative number by a negative number, the answer is always positive.When dividing a number by -1, it is the opposite of that numberWhen dividing a number by 1, it is the same number.

The same rules apply for division as they do to multiplication as well.

What you do to one side of the equation should happen to the other side.

Step 1: 6 - m = 3m + 14Step 2: 6 = 4m + 14 $\hookrightarrow \text{Adding m to both sides}$ Step 3: -8 = 4m $\hookrightarrow\text{Subtracting 14 from both sides}$ Step 4: 4m = -8Step 5: m = -2 $\hookrightarrow\text{Divide both sides by 4}$

Analyze:

When solving for variables, you want all the terms with that variable to one side.In the first step, we are subtracting m. To counter that operation, we add m to both sides.Similarly in step 2, we are adding 14, so to counter that, we subtract 14.In steps 3 and 4, we are multiplying m by 4. To counter that, we divide by 4

Hope this helps you out a lot!

Answer from: Quest

im trinna find out'

step-by-step explanation:

Answer from: Quest

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

⭐dhruv⭐

In the diagram of circle o, what is the measure of abc? 210 150
