6x+3y=6 and 8x+9y= -22 describes the outcomes of Clare and Noah.
Step-by-step explanation:
Let,
x represents the number of points for a goal.
y represents the number of points for a penalty.
Therefore,
6 goals = 6x
3 penalties = 3y
8 goals = 8x
9 penalties = 9y
According to given statment;
6x+3y=6 Eqn 1
8x+9y= -22 Eqn 2
6x+3y=6 and 8x+9y= -22 describes the outcomes of Clare and Noah.

For number 1 I think it is 1.02n because I added the like terms together
Well first lets do the distributive property so the left side is already done 28, now the right side -4 (2x+7) when you do that you get -8x-28. So now we have 28=-8x-28. So now I would move the -28 to the left side and when you move stuff to the other side you change the sign so the sign will be positive 28+28 which is 56. Now you have 56=-8x. Now divide both side by -8 to have -7=x
Your Answer: x = -7

Step-by-step explanation:
The area (A) of the sector of a circle is
A = area of circle × fraction of circle
= πr² × 
diameter = 12.4 ⇒ r = 6.2, thus
A = π × 6.2² × 
= π × 38.44 ×
= 
≈ 20.13 m² ( to 2 dec. places )
