The population of a country was estimated to be 1.114 x 10^8. On this day, the population of the world was 3.853 x 10^9.

Lelechka [254]

Step-by-step explanation:

To find how many people lived outside of the country we subtract:

3.853 × $10^{9}$ - 1.114 × $10^{8}$ = 3.7146 ×

To find the percentage of people living inside the country, we divide: $\frac{1.114 x10^{8}}{3.853 x10^{9}} =2.8913x10^{-2}$ percent or 2.89%. Which is extremely small.

5(x+3)-7(6-3)+29=50-3(8-x)

Sveta_85 [38]

Answer:

$\quad x=\frac{3}{2}$

Step-by-step explanation:

$7\left(6-3\right)=21$ , $\mathrm{Expand\:}5\left(x+3\right)-21+29:\quad5x+23$ , $\mathrm{Expand\:}50-3\left(8-x\right):\quad 3x+26$ , Subtract 23 and 3x from both sides and simplify: $2x=3$ , Divide both sides by 2 and simplify: $x=\frac{3}{2}$
