Which expressions are equivalent to 12 - 14/3m + 2/3m ?

yawa3891 [41]

ANSWER

The correct answers are option B and D.

$12 - 4m$

EXPLANATION

The given expression is

$12 - \frac{14}{3} m + \frac{2}{3}m$

We need to simplify the above expression in order to determine the option that is equivalent to it.

The least common denominator for the last two fractions is 3.

This implies that,

$= 12 + \frac{ - 14m + 2m}{3}$
We simplify to obtain,

$= 12 + \frac{ - 12m}{3}$

This further simplifies to give us,

$12 - 4m$

This is option B.

When we further factor -4, we get,

$-4(m-3)$

This is option D.

Convert from Decimal Notation to Scientific Notation

Brrunno [24]

Answer:

Hence, 87,50,000 can be expressed as $8.75 \times 10^{6}$ .

Step-by-step explanation:

- Given 87,50,000

- Use given, move the decimal point so that first factor is greater than or equal to 1 but less than 10 .

- Then count n and write in scientific notation.

Step 1 of 1

Consider 87,50,000.

8.75

So, 8.75 lies between 1 & 10 .

Now, Decimal moved to 6 places at left.

$8.75 \times 10^{6}$

So, $87,50,000=8.75 \times 10^{6}$ .
