Answer:

28.25 million

Step-by-step explanation:

Population of the country:

  • in 2001 - x million
  • in 2006 - 30.4 million

Population of the country as percent:

  • in 2001 - 100%
  • in 2006 - 100% + 7.6% = 107.6%

Write a proportion:

\dfrac{x}{30.4}=\dfrac{100}{107.6}

Cross multiply:

107.6\cdot x=30.4\cdot 100

Divide by 107.6:

x=\dfrac{30.4\cdot 100}{107.6}=\dfrac{3,040}{107.6}\approx 28.25

When 4(0.5x+2.5y-0.7x-1.3y+4) is simplified, what is the resulting expression?
padilas [110]

Answer:

-0.8x + 4.8y + 16

Step-by-step explanation:

4(0.5x+2.5y-0.7x-1.3y+4) = 4( 0.5x - 0.7x  + 2.5y - 1.3y + 4)

= 4( -0.2x  + 1.2y + 4)

= 4*(-0.2x)  + 4 *1.2y + 4*4

= -0.8x + 4.8y + 16
