Answer: x=-128/5
Step-by-step explanation:
-8-5x=120
-5x=120+8
-5x=128
x=-128/5
Base is 12 and height is 24
The average is found by adding the numbers and dividing by 2.
Since the average is 17, the total of the two numbers must equal 17 x 2 = 34.
One number is given as 11, so subtract 11 from 34:
34 - 11 = 23
The other number is 23.
Too check: add 11 and 23 and then divide by 2:
11 + 23 = 34
34/2 = 17.
