Answer:
15
Step-by-step explanation:
| -15 |
The absolute value means take the positive value of whats inside
| -15 | = 15
14-6=p
Or: 6+p=14
One of those should work :)
The answer is 8.

Answer:
- boat speed: 17.25 mph
- current: 2.5 mph
Step-by-step explanation:
Upstream, the speed of the current (c) subtracts from the speed of the boat (b) to give the net speed. Downstream, the speed of the current adds. We can make use of the relation ...
speed = distance/time
b-c = 29.5/2 = 14.75 . . . . . miles/hour
b+c = 59.25/3 = 19.75 . . . .miles/hour
Subtracting the first equation from the second, we get ...
(b+c) -(b-c) = 19.75 -14.75
2c = 5
c = 2.5
Then either equation can be used to find b:
b = 14.75 +c = 17.25
The speed of the boat in still water is 17.25 miles per hour; the speed of the current is 2.5 miles per hour.
300 messages would have to be sent or received in order for the plan to cost same each month.
Step-by-step explanation:
Given,
Cost per month = $30
Per text sent or received charges = $0.10
Let,
x be the number of texts sent or received.
A(x) = 0.10x+30
A comparable plan costs = $60 per month
Text messages are unlimited.
B(x) = 60
For the two plans to cost equal;
A(x) = B(x)
Dividing both sides by 0.10
300 messages would have to be sent or received in order for the plan to cost same each month.

Answer:
I dont know but example
Step-by-step explanation:
A cubic foot is a cube with a side length of one foot.
We know that, 1 foot = 12 inches.
So, 1 cubic foot is a cube with side length 12 inches.
You can use the formula for the volume of a prism, V=bwh , to convert cubic units.
Since 1 foot = 12 inches, replace b , w , and h with 12 .
V=(12)(12)(12) =1,728
So, 1 cubic foot is equal to 1,728 cubic inches.
