Answer:
45 people are members at the tennis club
Step-by-step explanation:
Let the number of people in the tennis club be denoted as "x".
Since each of them donated $12.45, then total donated = 12.45x
Since they had $50.25 left over after paying the cost of $510 for the ball, then;
12.45x - 510 = 50.25
12.45x = 510 + 50.25
12.45x = 560.25
x = 560.25/12.45
x = 45
Answer:
1 skateboard will cost $73 and the other will cost $72
Step-by-step explanation:
Skateboard A (Original) = X
Skateboard B (+$1) = X + 1
Solving for X
(x + 1) + x = 145
2x + 1 - 1 = 145 - 1
2x = 144
2/2 = x
144/2 = 72
x = 72
Answer:
9:100
Step-by-step explanation:
Turn 9% into a fraction by putting it over a hundred:
9/100
Then simply change the '/' into ':'
If this were another fraction, let's say, 4/6, then you'd put it in simplest form, which is 2/3 = 2:3
