define the 3 numbers
smallest number = x
middle number = x + 2
largest number = x + 4
write the equation
sum of the smallest number and twice the middle number
20 more than the largest number
equal the expressions
the numbers should be 10, 12 and 14
Answer:
C
Step-by-step explanation:
The diagram shows the system in equilibrium. Left part consists of 3 circles, 2 triangles and 6 squares. Right part consists of 2 circles, 5 triangles and 3 squares.
If this system is in equilibrium, then the mass of the left part is the same as the mass of the right part.
<u>The mass of the left part:</u>
<u>The mass of the right part:</u>
Hence,
Answer: I believe you may be right although I can't really explain it in detail
1. j=13 because 13+12=25
2. k=20 because 20-16=4
