Answer:
x = 12
Step-by-step explanation:
The total of all the angle is 180 degrees so just divide 180 by the total number of x's which is 5+4+3+2+1 = 15
180/15 = 12
If you wanted to know how much each angle is just plug in 12 for x.
So first angle is just X so it is 12 degrees.
Second angle is 2X so 2x12 = 24 degrees.
and so on for all the angles.
The answer is B because when yku combine like terms (x) 2/5 + 1/5 you get 3/6. Then when you simplify the equations, you turn -1/4 into -2/8 to match the 5/8. From there you just subtract 2/8 from 5/8 getting 3/8.
Answer:
Slope is m = -3
find equation using two point formula-- y= -3x - 5
It will take an additional 8 weeks to reach a height of 48 centimeters.
y = 4.5x
Since, the maximum height is 48 cm and the plant has already grown 12 cm, we deduct the 12 from 48 to get the additional weeks it needs to grow.
48 - 12 = 4.5x
36 = 4.5x
36/4.5 = 4.5x / 4.5
x = 8 weeks.
