Mathematics

Kruka [31]3 years ago
5 0

Answer:

x = ± 2\sqrt{3}

Step-by-step explanation:

Given

12 - x² = 0 ( add x² to both sides )

12 = x² or

x² = 12 ( take the square root of both sides )

x = ±\sqrt{12}

  = ± \sqrt{4(3)} = ± 2\sqrt{3}

If US$1.00 is equivalent JA $75.00, What amount, in US dollars is equivalent JA $3300.00
emmasim [6.3K]

Answer:

It is US $44.00 Equivalent

Step-by-step explanation:

Using ratios (essentially fractions):

1 US : 75 JA

OR

1 US = 75 JA

Dividing both sides by 75 gives us:

\frac{1}{75}US = 1 JA

So if we have 3300 JA we can multiply both sides to get:

44 US = 3300 JA
