<em>*To solve inequalities is similar to solving equations: isolate the desired variable to one side.</em>
So firstly, distribute -8 to (p + 1):
Next, combine like terms:
Next, add 8 to both sides:
Lastly, divide both sides by -3. Now since you are dividing by a <u>negative</u>, you will be flipping the inequality symbol as well.<u> Your final answer will be </u>
Given :
a paddle boat travels upstream = 12 miles
a paddle boat travels downstream = 20 miles
speed of the current = 2 miles per hour
Let the speed of the boat =x
Let the time taken = t
We know the distance for upstream D= (boat speed - current speed) * time
the distance for downstream D= (boat speed + current speed) * time
Plug in all the values and variables in the distance
For upstream 12 = (x-2)t, then
For downstream 20 = (x+2)t then
we got two equations for t, equate it and solve for x
Cross multiply it
12(x+2) = 20(x-2)
12x + 24 = 20x - 40 (subtract 12x and add 40 on both sides)
64 = 8x
x= 8
the speed of the boat in still water = 8 miles per hour
Answer:
Step-by-step explanation:
1. Three zeroes equal 1,000
2. One zero equal 10
3. One zero equal 10
4. Look at the value without the zeroes
5. Three zeroes equal 1,000
6. Look at the value without the zeroes
7. Since 890 has one zero, one more zero equal 10
8. Look at the value without the zeroes
9. Same as 8.
10. Three zeroes equal 1,000
11. Look at the value without the zeroes
12. Three zeroes equal 1,000
13. Same as 11.
14. Same as 13.
15. N/A
16. I am not sure about this one cause I don't know if there are more zeroes or not, but same as 13.
Step-by-step explanation:
A fraction is in simplest form when the top and bottom cannot be any smaller, while still being whole numbers. To simplify a fraction: divide the top and bottom by the greatest number that will divide both numbers exactly (they must stay whole numbers).
