Solve the equation. 2m/3-1=3/4+m (please show work)

1 answer:

3 0

The first step is to get the variable on both sides, do this by subtracting m.

This leaves you with 2m/3 -1 -m = 3/4

Then multiply by 3 on both sides to eliminate the fraction.

This leaves you with 2m-3-3m = 9/4

Then isolate the variable by adding 3 to both sides.

This leaves you with 2m-3m = 3 9/4

This can simplify into -m = 5 1/4 or 21/4

Multiply by -1 to keep the variable positive

The final answer is m = -21/4 (or -5 1/4, your choice)

Which is the best estimate for StartFraction (8.9 times 10 Superscript 8 Baseline) Over (3.3 times 10 Superscript 4 Baseline) En

ratelena [41]

Answer:

$2.7 * 10^{4}$

Step-by-step explanation:

Given the expression $\frac{8.9*10^{8} }{3.3*10^{4} }$ , to express the the fraction in scientific notation, we will apply the law of indices below;

According to one of the laws of indices, $\frac{a^{m} }{a^{n} } = a^{m-n}$

Applying this to the fraction;

$= \frac{8.9*10^{8} }{3.3*10^{4} }\\\\= \frac{8.9}{3.3} * \frac{10^{8} }{10^{4} }\\\\ = \frac{8.9}{3.3} * 10^{8-4}\\\\ = \frac{8.9}{3.3} *10^{4}\\\\ = 2.697 * 10^{4}$
