Answer:
15
Step-by-step explanation:
Simply subtract the smaller number from the bigger number, and divide by 2. Or add the two numbers together and divide by 2.
I'm not quite sure if this is what you need, but I am going to solve these equations by elimination. x= 8/17 and y = 11/17 (8/17, 11/17).
Answer:
180 minutes
Step-by-step explanation:
90×60/30= 180
The value of the expression will decrease as x increases.
You can test this out by plugging in random numbers in place of x, like 20-5=15 and 20-8=12. The value of the expression (or the answer) is becoming smaller as the value of x becomes larger.
Hope this helps :)
