Answer: The value of x in terms of h is x=-3h

The value of x when h is 4 is x=12

Step-by-step explanation: for the first one you want to get x alone on one side

The second one is just plugging in 4 into h.

Suppose the population in a town average growth rate of 18% if there are 15500 people now living in town in about how many years

madam [21]

This is just a matter of solving for $x$ in the given equation.

$30000=15500\times1.18^x$
$\implies 1.935=1.18^x$
$\implies \log_{1.18}(1.935)=\log_{1.18}(1.18^x)$
$\implies 3.988=x\implies x\approx 4\text{ years}$

A merchant mixed 10 lb of a cinnamon tea with 2 lb of spice tea. The 12-pound mixture cost $19. A second mixture included 16 lb

zubka84 [21]

Hey there!!

Take the cinnamon tea as ' x ' and spice tea as ' y '

10 x + 2y = 19 -------------- ( 1 )

16x + 10y = 44 --------------- ( 2 )

Multiply the first equation by 5

50x + 10y = 95

16x + 10y = 44

Subtract the second equation from the first

34x = 51

x = 51 / 34

x = $1.5

Substitute this in any other equation

15 + 2y = 19

2y = 4

y = 2

Cinnamon = $1.5

Spice tea = $2

Hope helps!
