Answer:
x>3
Step-by-step explanation:
- First distribute the 3 to the inside of the parentheses:
- you should then get 3x+12>21
- next you want to subtract over 12 from both sides:
- then divide 3 over on both sides
- you should then get x>3 for your final answer

draw a right-angled triangle with the line as hypotenuse.
use the scale on each axis to find the triangle's: vertical length. horizontal length.
work out the vertical length ÷ horizontal length.

Answer:
Step-by-step explanation:
The time for each canoe is 3.5 hours
The total distance traveled by the first canoe is not known. Nor is the distance for the second canoe. We do know that the difference is 5.25 miles.
So let the rate of the slower canoe = x
Let the rate for the second canoe = 2x
The first canoe goes a distance of 2*x * 3.5 = 7x
The second canoe goes a distance of 3.5x
The difference = 7x - 3.5x = 5.25
3.5x = 5.25 divide by 3.5
x = 5.25/3.5
x = 1.5 which is the rate of the slower canoe
2x = 3 which is the rate of the faster canoe
Answer:
#1
Step-by-step explanation:
Because To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.
