Answer:

W = 4 in

Step-by-step explanation:

Here W is the width and L the length.  Then L = W + 3 in.

The formula for the perimeter of a rectangle is P = 2W + 2L.

Thus, 22 in = 2(W) + 2(W + 3), which reduces to

11 in = W + W + 3 in, or

8 in = 2W, and W = 4 in

Ten less than twice a number is the same as 7 times the number. find the number
Dafna11 [192]
The number is -2 // Math [n is equivalent to number]: 2n -10 = 7n
                                                                                    2n = 7n + 10
                                                                                    -5n = 10
                                                                                    -n = 2
                                                                                    n = -2

1/2 (x−8)+1=2( 1 8 x−1)
nalin [4]

Answer:

The solution for the given algebraic equation is \frac{ - 2}{71}

Step-by-step explanation:

Given algebraic equation as :

\frac{1}{2} ( x - 8 ) + 1 = 2 ( 18 x - 1 )

Now solving the equation while opening the brackets

So, \frac{1}{2} × x - \frac{1}{2} × 8  + 1 = 2 × 18 x - 2

Or, \frac{x}{2}  - \frac{8}{2}  + 1  = 36 x - 2

or,  \frac{x}{2}  - 4 + 1 = 36 x - 2

or,  \frac{x}{2}  - 3 = 36 x - 2

or,  \frac{x}{2} - 36 x = - 2 + 3

Or,  \frac{x}{2} - 36 x = 1

or, \frac{x - 72 x}{2} = 1

or, \frac{- 71 x}{2} = 1

∴ 71 x = - 2

I.e x = \frac{ - 2}{71}

Hence The solution for the given algebraic equation is \frac{ - 2}{71}    Answer

What is the circumference if the diameter is 21in and pi is 22/7
Ede4ka [16]

Answer:

66 in

Explanation:

the circumference can be calculated as:

C=d\cdot\pi

Where d is the diameter and π is 22/7.

So, replacing the values, we get:

C=21\cdot\frac{22}{7}=\frac{21\cdot22}{7}=\frac{462}{7}=66\text{ in}

Therefore, the circumference is 66 in.

Estimate by rounding the largest number to tens and then divide.<br> 200 ÷ 8 is approximately
aivan3 [116]

Hello!

If you divide 200 by 8, that would equal 25. Since it looks like you already simplified, this would be your answer!

Hope this helped! Let me know if you have any other questions!

Godspeed,
