2+x=2x-15
>> 2+15=2x-x
>> 17 = x
So the answer is <u>17</u>
Answer:
pq =28
Step-by-step explanation:
you set up the equation by making them equal each other 3x+4= 5x-12 and solve From there
Answer:
14 ohms
Step-by-step explanation:
The resistance varies directly with length, so increasing the length by a factor will increase the resistance by the same factor.
__
The length of the wire increased by a factor of 1.4 from 100 ft to 140 ft. That means the resistance will increase by a factor of 1.4 from 10 ohms to 14 ohms. (The diameter did not change.)
The longer wire will have a resistance of 14 ohms.
Answer: 3 hours and 20 minutes
Step-by-step explanation:
First , you convert your fraction to a decimal.
6/5 = 1.2
Second , you subtract 4 minus 1.2 to see how much of the work shift does she have left ( since 1.2 hours is what she worked).
4 - 1.2 = 2.8 = 2 hours and 80 minutes (60 minutes is an hour) = 3 hours and 20 minutes
