Answer:
first get the total ratio; 2 + 5 = 7
so the fraction of blue marbles is 5/7
then assume the number of total marbles to be k
then use the expression;
5/7*k = 65
7*5/7 * k = 65*7
5k =455
5/5k = 455/5
k = 91
then calculate the number if red marbles from;
x = 2/7*91
x = 26
Therefore there are 26 red marbles.
Answer:
125$ worth because you would not spend it all if you picked 625 and the others would give way too many away
1. Find the slope
2. Y - Y1 = M ( X -X1) Plug the value. M is the slope and the point (X1,Y1)
