Answer:

The answer is D.

Step-by-step explanation:

On a number line

:-Adding a positive number means moving to the right

-Adding a negative number means moving to the left

basically the easiest way to explain is pretend to have a point at -3 if you move it to the right 2 times your point will now be at -1.

Answer:

Because it is 3 units to the left of 2 on a horizontal number line. (first answer)

Step-by-step explanation:

when you substract you take the number your substracting and move it to the left of the number line the number your substracting.

In this case you have 2 and you substract 3 so from 2 you move 3 spaces from the numberline to the left

Which is the first one.

Answer:

$\frac{7}{8} \div \frac{1}{2} = \frac{7}{4}$

Step-by-step explanation:

Here we are given four equations and we have to find the equation that gives the number of half inches that are in $\frac{7}{8}$ inches.

To find how many half inches i.e. $\frac{1}{2}$ inches are there in $\frac{7}{8}$ inches we have to divide $\frac{7}{8}$ by $\frac{1}{2}$ .

So, the equation that will give the result is $\frac{7}{8} \div \frac{1}{2} = \frac{7}{8} \times \frac{2}{1} = \frac{7}{4}$ (Answer)

What is the value of x<br><br> 1/5 = 25/x

Mama L [17]

First getting x as a numerator rather than a denominator. Then grouping like terms by moving 5 from the left side to the right. Work below:
$\frac{1}{5} = \frac{25}{x} \\ \frac{1}{5}*x = \frac{25}{x}*x\\ \frac{1}{5}x = 25\\\frac{1}{5}x * 5 = 25*5\\x=125$
