Answer:

<h2>The answer is 3</h2>

Step-by-step explanation:

Let the number be x

The statement

twice a number is written as

2x

The sum of twice a number and seven is written as

2x + 7

The result is 13

So we have

2x + 7 = 13

Subtract 7 from both sides

That's

2x + 7 - 7 = 13 - 7

2x = 6

Divide both sides by 2

That's

\frac{2x}{2}  =  \frac{6}{2}

We have the final answer as

<h2>x = 3</h2>

Hope this helps you

Answer:

<1 = 33 degrees

<2 = 33 degrees

<3 = 114 degrees

Step-by-step explanation:

<1 and <2 = x

<3 = 3x+15

<1 + <2 + <3 = 180 degree

x + x + 3x + 15 = 180

5x = 180 - 15

x = 165/5

x = 33

<3 = 3(33)+15

= 114 degrees

Solve it:3/10×7/10=21/100
egoroff_w [7]
I'm gonna guess you're asking if the equation is true or false.
Well, the equation is True. 3/10 * 7/10 is 21/100, or in decimal form 0.21.
Converting 21/100 to a decimal is 0.21.
0.21 = 0.21.
21/100 = 21/100.

Step-by-step explanation:

x^3+6x^2+11x+6/x^2+4x+3

= x^3+6x^2+11x+6/x^2+4x+3

= (x+1)(x+2)(x+3)/(x+1)(x+3)

=x+2
