Jon and lexi are playing a marble game. according to their rules, 6 points are awarded for each red marble collected and 2 points are awarded for each blue marble collected. which expression represents jon's total score if he has r red marbles and b blue marbles?

Each red marble is worth 6 points. For r red marbles, that is 6r points.

Each blue marble is worth 2 points. For b blue marbles, that is 2b points.

Now add the two expression of points to find the total number of points.

total score = 6r + 2b

If Jon has r red marbles and each red marble is worth 6 points, we would write 6r as the number of points received from the red marbles.

Similarly, if Jon has b blue marbles and each blue marble is worth 2 points, we would write 2b as the number of points received from blue marbles.

Then, to find the total number of points, just add the two equations together:

6r + 2b

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

it has changed from the width and the height.
