Answer:
9
Step-by-step explanation:
sorry if wrong
So, we’re looking for the amount of money Tom needs to spend to get his free meal.
X + 30.25 >
X > 9.75
X is the additional amount that Tom needs to spend. You subtract 30.25 on both sides in order to solve for x.
So, your answer would be at least $19.75
25 is equal to 20% of 125
As the increase is 75 (200-125), you've then got to divide the increase by each part to find out how many times it increases.
75/25= 3
20*3= 60
Therefore, there is an increase of 60%

Answer:
r = 7
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
x² + y² = 49 ← is in this form
with r² = 49 ⇒ r = 
= 7
