Answer:
15
Step-by-step explanation:
there are 2 red marbles for every 5 blue marbles, and we know that there are 6 red marbles total.
2x3=6, so we know that there are 3 sets of 2 red marbles, meaning there is also 3 sets of 5 blue marbles.
So there are 3x5=15 blue marbles in the bag
This function is in the form y=mx + b where m is your slope, so the slope is -2
Answer: 16 miles
Explanation:
I believe it would be 16 miles, if he starts off at 6 miles on day one and goes up 1/2 mile every day, he would be up a mile every other day, basically on day 3 he would be at 7 and day 5 at 8 miles, if the pattern continues he would be at 16 miles by day 21.
It can be written as 5 x 10^ -11 or 0.5 x 10^ -10
Hope it helps.
