5x- SR 40= 0., add to the other side, 5x= SR 40. divide both sides by 5, x= SR of 8, or 2 SR 2
The answer for this will be a
On her third test she should get 67 marks
so therefore 71 + 87 + 67 = 225
225 divide by 3 (as three tests) = 75

Answer:
Circumfrence: 40.21
Radius: 6.4
Step-by-step explanation:
For radius, you only have to divide the diameter (in this case 12.8) by 2 which gives us 6.4
For Circumference, plug in the radius in the formula C=2π(6.4), and that gives us 40.21
