<em>Answer and Step-by-step explanation:</em>

<em>\Huge \boxed{b=-1}.</em>

<em>Step 1 : Simplify both the sides of the equation :</em>

<em>7b-37=4(5b-6)\\7b+-37=(4)(5b)+(4)(-6)\\7b+-37=20b+-24\\7b-37=20b-24</em>

<em>Step 2 : Subtract 20b from both sides :</em>

<em>7b-37-20b=20b-24-20b\\-13b-37=-24</em>

<em>Step 3 : Add 37 to both sides :</em>

<em>-13b-37+37=-24+37\\-13b=13</em>

<em>Step 4 : Divide both sides by -13 :</em>

<em>\frac{-13b}{-13}=\frac{13}{-13}</em>

<em>b=-1</em>

<em />

<em>That's our final answer !</em>

Step-by-step explanation:

1) 7b – 37 = 4(5b - 6)

7b - 37= 20b - 24

-13b = 13

dividing both sides by -13

b=-13/13=-1

<h3> b = -1</h3>

Hey there! :D

Let's break this up piece by piece. 

The first two, let's say that the first boxes represent the bottom of the chart. 

The first far left box would be 13. 

The next one 9. 

Going across, 10 and 11. 

Two more up. 

7 and 3. 

One more across, which is 4. 

So, 13, 9, 10, 11, 7, 3, 4  would be the ones you would want to shade.

I hope this helps!

Answer:

7(x+3)

Step-by-step explanation:

7x+21

7x = 7*x

21 = 7*3

We can factor out a 7 from both terms.  What remains is what is inside the parentheses

7(x+3)

If line AD is a tangent to circle B at point C, and m∠ABC = 55º, what is the measure of ∠BAD?
4vir4ik [10]
The tangent AD at point C forms a right angle to circle B, such as ∠ACB=90° and ∠ABC=55°.

We also know that the summation of all angles in a triangle is 180°. Thus we have the expression below:
180°=∠ABC + ∠ACB + ∠BAD
180°=55°+90°+∠BAD
∠BAD=35°

Therefore, the answer is 35°.
