8 0

Step-by-step explanation:

$\frac{x}{8} + \frac{5}{2} = \frac{3}{2}$

by taking L.C.M

$\frac{2x + 40}{8} = \frac{3}{2}$

$cross \: the \: values$

$2(2x + 40) = 8 \times 3$

$4x + 80 = 24$

$4x = 24 - 80$

$4x = - 56$

$x = \frac{ - 56}{4}$

$x = - 14$

Answer:

Oxygen; 34.01°C

Step-by-step explanation:

The oxygen freezes first as it has a higher (warmer) freezing point. For both to freeze, the temperature must drop a further 34.01°C as:

-218.79 - (-252.8)

= 252.8 - 218.79

= 34.01

Answer:

Option B

Step-by-step explanation:

Given the following question:

In order to find the answer, we need to convert the scientific notation into standard notation and then simplify by subtracting the decimals. Then we convert the standard notation back into scientific notation.

$0.0007 - (4.9\times 10^{-7} )$
$4.9\times10^{-7} =0.00000049$
$0.0007-0.00000049$
$0.0007-0.00000049=0.00069951$
$=0.00069951$
$0.00069951=6.9951 \times10^{-7}$
$=6.9951 \times10^{-7}$

Your answer is "6.9951 × 10^-7" or option B.

Hope this helps.
