The answer is B
Step-by-step explanation:
2x+2y =10 and y= -x +5
These are not in the same form so thats the first step
2x+2y=10
we minus 2x from both side which turns into
2y=-2x+10 (the variable always comes first)
Secon step is to divide 2 from the y to everything so 2y divided by 2 = y
-2 divided by 2 is -x and 2 divided by 10 is 5 and now you have the same equations which leads to infinite
y=-x+5

Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm
