If it is :

10 -  \frac{ (3x - 1)}{2} =  \frac{(6x + 3)}{11} \\

Multiply both sides by 22

(22 \times  10) - 11 \times (3x - 1) = 2 \times (6x + 3) \\

220   -  33x  +  11 = 12x + 6

- 33x + 231 = 12x + 6

Plus both sides <em>3</em><em>3</em><em>x</em>

231 = 33x + 12x + 6

231 = 45x + 6

Subtract sides minus 6

231 - 6 = 45x

45x = 225

Divided sides by 45

x =  \frac{225}{45} \\

x = 5

If it is :

\frac{10 - (3x - 1)}{2} =  \frac{6x + 3}{11} \\

Multiply sides by 22

(11 \times 10) - 11 \times (3x - 1) = 2 \times (6x + 3) \\

110 - 33x + 11 = 12x + 6

- 33x + 121 = 12x + 6

Plus sides <em>3</em><em>3</em><em>x</em>

121 = 12x + 33x + 6

121 = 45x + 6

Subtract sides minus 6

121 - 6 = 45x

45x = 115

x =  \frac{115}{45} \\

x =  \frac{23}{9} \\

If the perimeter of a square is 20, find the length of a diagonal
avanturin [10]

Answer:

7.07

Step-by-step explanation:

<h2><u>Length</u></h2>

a square has equal length on each side

hence is the perimeter is 20 it means that :

each side is 20/4 = 5

we can make a diagonal line which create 3 right angled triangles

2 sides of the triangle are 5 , this is the base and the height

to find the length we can make use of the Pythagoras theorem

c^2 = a^2 + b^2

c is the hypotenuse ( the diagonal;)

a and b are the opposite and adjacent

hence :

c^2 = 5 ^2 + 5^2

c^2 = 50

c = \sqrt{50}

c = 7.071

to 3sf

<h3><u>diagonal length  = 7.07</u></h3>

Which equation describes the circle
deff fn [24]

Answer:

B. (x-5)²+(y+1)² = 49

Step-by-step explanation:

An equation of a circle with center (h, k) and radius r is

\large \boxed{ {(x - h)}^{2}  +  {(y - k)}^{2}  =  {r}^{2} }

We have all given information we need. Our h is 5 - Our k is -1 and our radius is 7

Substitute these values in

\large{ {(x - 5)}^{2}  +  {(y - ( - 1))}^{2}  =  {7}^{2} } \\  \large{ {(x - 5)}^{2}  +  {(y  + 1)}^{2}  =  {7}^{2} } \\  \large{ {(x - 5)}^{2}  +  {(y  + 1)}^{2}  = 49 }

So the answer is B choice.
