6 0

Answer:

Step-by-step explanation:

Here, y = 10 million = 10000000

10000000 = \frac{1}{2}*(1.21)^x

Simplifying and taking natural log on both sides:

ln(20000000) = x*ln(1.21)

x = 88.19 years

Please help it will be brainlist please make sure you are 100% the awnser is right
Dominik [7]

Answer:

Step-by-step explanation:

Step 1: Sum of angles on a straight line is 180

Step 2:

2x + 25 + y = 180

2x + y = 180 - 25

2x + y = 155  (1)

Step 3:

3x - 10 + y = 180

3x + y = 180 + 10

3x + y = 190    (2)

Step 4: Substract equation 1 from 2

3x + y - 2x - y = 190 - 155

      x = 35

Step 5:

Substitute x in equation 1 to find y

2x + y = 55

2(35) + y = 155

70  +  y = 155

  y = 155 - 70

   y = 85
