Answer:
x = 12
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
9x + 11 + 3x - 15 + 2x + 16 = 180, simplify left side
14x + 12 = 180 ( subtract 12 from both sides )
14x = 168 ( divide both sides by 14 )
x = 12
Answer:
His rate of change is 7 pounds per week.
Step-by-step explanation:
Rate of change = change in weight ÷ change in time
change in weight = 188 - 167 = 21 pounds
change in time = 6 - 3 = 3 weeks
Rate of change = 21 ÷ 3 = 7 pounds/week
