Answer:

$n + $20

Step-by-step explanation:

Jim already has $n, and his mom has given him $20. We know we are not taking $n and subtracting $20, since his mom is adding that on to what he already has, we know we are not dividing, not multiplying but adding.

Conclusion : To find how much money he has now you would use the expression $n + $20

Answer:

$\huge\boxed{Diameter=11cm}$

Step-by-step explanation:

Important information:

Circumference of a circle= $\pi*diameter$

Method:

To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.

Step By Step:

1) Rearange the formula to make the diameter the subject.

$diameter=\frac{circumference}{\pi}$
