Answer:
1) 8.5
2) 60
3) 69.3
4) 6.8
5) 3.6
6) 10.5
Step-by-step explanation:
Take out the decimal of the estimated factors and multiply. Count how far to left the decimal is in the factors. In the product, put the decimal as many to the left as it was in the factors. (ex. 6.93 x 42, 6.93 rounds to 6.9, 42 rounds to 40, 69 x 40 = 2,760, move the decimal over one for correct place value, 6.9 x 40 = 276.0 <em>or </em>276)
Simple it says you use 33 drops of yellow originally and 44 drops of blue it appears that each drops are 11 drops lesser (from blue to yellow). Therefore, add 11 to 1212 and you get your answer.
Answer:
First lets find the solutions to each inequality.
-2x
10 and -2x>10 (divide both sides by -2 to solve)
x
-5 and x<-5
x
-5 tell us that x could be -5 or less.
x<-5 tells us that x could be -6 or less.
The first one is less than or equal to which tells you that there is a possibility that the number is shows is could be an answer
Hope this helps ;)

Let's solve for x:
100x=1000
Divide by 100
x=10
You should expect to win 10 times.
A) Divide total miles by total time:
