Answer:
∠ ABC = 87°
Step-by-step explanation:
∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so
2x - 17 + x + 32 = 180 , that is
3x + 15 = 180 ( subtract 15 from both sides )
3x = 165 ( divide both sides by 3 )
x = 55
Then
∠ DBE = x + 32 = 55 + 32 = 87° , thus
∠ ABC = ∠ DBE ( vertical angles )
∠ ABC = 87°

Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1
so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)

Answer:
Hi. My explanation is down below. Pls mark as brainliest if its good :)
Step-by-step explanation:
1. Why is 3/3 of 4 equal to 4?
3/3 of 4 = 4 because 3/3 = 1
And 1 of 4 is 4
Also 3/3 of 4 = 3/3*4
since 3/3 = 1
Its the same as 1*4 or 4
2. Why is 2/3 of 4 less than 4
2/3 is less than one, and since the identity property of multiplication says that any number times one is the number itself, a number that is less than one will result to being less than itself.
Proof
3/3 * 4 = 4
2/3*4 = 8/3 = 2 2/3
3. Why is 4/3 of 4 greater than 4?
4/3 is greater than one. 4/3 = 1 1/3
So you will multiply 4 by itself, and then you add another 1/3*4
So the product will be 4 + 1 1/3 = 5 1/3
If my answer is incorrect, pls correct me!

A stone fell from the top of a cliff into the ocean.
In the air, it had an average speed of 16 m/s. In the water, it had an average speed of 3 m/s before hitting the seabed. The total distance from the top of the cliff to the seabed is 127 meters, and the stone's entire fall took 12 seconds.
How long did the stone fall in the air and how long did it fall in the water?
The stone fell in the air for ___seconds and fell in the water for ___ seconds.
Answer:
The stone fell in the air for 7 seconds and fell in the water for 5 seconds.
