Answer:
Step-by-step explanation:
let a be the number of tennis balls.
let b be the number of tennis rackets.
We write determine the ratio of balls to rackets by dividing the number of balls by the number of rackets:
For every one ball, there 5 thirds of a racket.
We plot this function on a graph to visualize our model;
Answer:
Percentage of interest at which the money is invested = 5%
Time for which the money is invested = 3 years
The final amount after 3 years = $820
Let us assume the principal amount = x dollars
We can conclude that the principal amount invested was $708.35.
Answer:
Step-by-step explanation:
1.5x - 15 dollars = x - 20 Add 15 to both sides.
1.5x - 15 + 15 = x - 20 + 15
1.5x = x - 5 They will never coincide.
1.5x-x = - 5
0.5x = - 5 Multiply by 2
x = - 10
I would check your question.
Sum of 5 numbers = 39*5 = 195
largest two numbers sum = 49*2 = 98
median = 40
sum of smallest two numbers = 195-(98+40) = 195-138 = 57
I don't really know how to explain it to you but what I can tell you is that in 1 centigram there are 10 milligrams.
