The sum of three consecutive integers is three times the middle one: if we call the middle one , the three numbers are
So, their sum is
Which is three times the middle one.
So, if the sum of three consecutive intergers is 48, the middle one must be 48/3 = 16.
So, the three numbers are 15, 16 and 17

Solve for A (Area)
Since we do not have a given value for , this is as far as we can condense the equation.
Answer:
-2196
Step-by-step explanation:
Each number in the series is being multiplied by POSITIVE 6. Therefore,
-216 x 6 = -2196 .
Answer:
x= 15
Step-by-step explanation:
2x+3(x-10)=45
2x+3x-30=45
Combine like terms:
2x+3x-30 turns into 5x-30= 45
5x-30=45
+30 +30
5x = 75
x = 15
