Sue's average score for three bowling games was 162. In the second game, Sue scored 10 less than in the first game. In the third
natali 33 [55]

Answer:

Her score in the first game was 173.

Step-by-step explanation:

Sue's total score for the 3 games = 3*162 = 486 points.

Let her score in the first game be x points. Then in the second game she scored (x - 10)  and in the third, ( x - 10 - 13) points:

x + (x - 10) + (x - 23) = 486

3x - 33 = 486

3x = 519

x = 173 (answer).

A line segment that goes from one side of the circle to the other side of the circle and doesn't go through the center is:
rewona [7]

A line segment that goes from one side of the circle to the other side of the circle and doesn't go through the center is called chord of circle.

Since,

The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.

The diameter is the length of the line through the center that touches two points on the edge of the circle.

So, we can say that every diameter of a circle is always called chord (longest chord) but every chord of the circle is not a diameter because the diameter passes to the circle's center but it not necessay that evey chord will pass through the center of the circle. Some, line segment goes from one side of the circle to the other side and doesn't pass through centre then for this case the line segment is called chord of the circle.

Hence, a line segment that goes from one side of the circle to the other side of the circle and doesn't go through the center is called chord of the circle.

lys-0071 [83]

Answer:

8x+8y

Step-by-step explanation:

y + 3x + 4y + 2x + 3y +3x

<em>With</em><em> </em><em>this</em><em> </em><em>we</em><em> </em><em>group</em><em> </em><em>x</em><em> </em><em>with</em><em> </em><em>x</em><em> </em><em>and</em><em> </em><em>y</em><em> </em><em>with</em><em> </em><em>y</em><em> </em><em>and </em><em>in</em><em> </em><em>ascending</em><em> </em><em>order</em><em> </em><em>so</em><em> </em><em>x</em><em> </em><em>comes</em><em> </em><em>before</em><em> </em><em>y</em>

3x+2x+3x

And the y with y

y+4y+3y

Which is;

3x+2x+3x+y+4y+3y

8x+8y
