List the following numbers in order from least to greatest. a) 3.5× 10/3 B) 3.5× 10-2 C) 5.3 × 10/3

Crazy boy [7]

Answer:

$3.5*10^{-2}, 3.5*10^3, 5.3*10^3$

B, A, C

Step-by-step explanation:

This is scientific notation. The numbers $3.5 * 10^3\\3.5 *10^{-2}\\5.3 * 10^3$ can be ordered least to greatest by looking at their digits and exponents. Since a -2 as an exponent is present, this means this is a small decimal and is the least. 3.5 and 5.3 have the same exponent of 3 but 5.3 is greater than 3.5 so its the greatest. The order is

$3.5*10^{-2}, 3.5*10^3, 5.3*10^3$

Please show your work and explain it.

Answer:

$f(x)=\dfrac{x+2}{2(x-2)}$

Step-by-step explanation:

Remember when you divide fractions, you need to get the reciprocal of the divisor and multiply. So your first simplification would be:

$\dfrac{x^2+4x+4}{x^2-6x+8}\div\dfrac{6x+12}{3x-12}\\\\=\dfrac{x^2+4x+4}{x^2-6x+8}\times\dfrac{3x-12}{6x+12}\\\\=\dfrac{(x^2+4x+4)(3x-12)}{(x^2-6x+8)(6x+12)}$

Next we factor what we can so we can further simplify the rest of the equation:

$=\dfrac{(x^2+4x+4)(3x-12)}{(x^2-6x+8)(6x+12)}\\\\=\dfrac{(x+2)(x+2)(3x-12)}{(x^2-6x+8)(6(x+2))}\\\\$

We can now cancel out (x+2)

$=\dfrac{(x+2)(3x-12)}{(x^2-6x+8)(6)}$

Next we factor out even more:

$=\dfrac{(x+2)(3)(x-4)}{(x-2)(x-4)(6)}$

We cancel out x-4 and reduce the 3 and 6 into simpler terms:

$=\dfrac{(x+2)(1)}{(x-2)(2)}$

And we can now simplify it to:

$=\dfrac{x+2}{2(x-2)}$

Solve for x:<br> .<br> 3x – 1 = –2x + 39

zysi [14]

Step-by-step explanation:

$3x-1=-2x+39$

Add 1 to both sides.

$3x=-2x+40$

Add 2x to both sides.

$5x=40$

Divide 40 by 5.

x = 8

Target sells 24 bottles of water for $3, and 36 bottles of water for $4. Which is the better buy and by how much

Oksana_A [137]

The better buy would be the 36 bottles of water for 4$ because it would be 9 bottles per dollar other than the 24 which is 8 bottles per every dollar. Hope it helps!
