The correct answer would be D. We know that A is incorrect because A shows that she would study for less than 1 1/4 hours. We know that B is incorrect because this shows that she can study exactly 1 1/4 hours. C is incorrect because even though the inequality is right, there are only 24 hours in a day so she cannot study up to 30 hours in one night.

Hope this helps

Math 7a using number sense to solve equations

Anika [276]

Simple...

you have: $\frac{n}{3} =12
$

and

$\frac{n}{3} =-12$

To solve for.... $\frac{n}{3} =12$

Multiply to remove the denominator-->>

$3* \frac{n}{3} =12*3$

n=12*3

n=36

Then-->>>

$\frac{n}{3} =-12$

Do the same thing-->>

$3* \frac{n}{3} =-12*3$

n=-12*3

n=-36

Thus, your answer.

What is -0.8+1.4n=2+0.7n

Sergio [31]

Answer:

n=4

Step-by-step explanation:

To solve combine your like terms.

You can start by adding 0.8 to both sides and subtracting 0.7n from both sides.

$-0.8+1.4n=2+0.7n\\1.4n=2.8+0.7n\\0.7n=2.8$
