Answer:

Step-by-step

1+m/2 -1 =-3+1

m/2 = -2

2(m/2) = 2(-2)

m = -4

when m was -8

-8 = -4

-8 ≠ -4

when m was 8

8 = -4

8 ≠ -4

Answer:

$No\:Solution$

Step-by-step explanation:

$\frac{\left|m\right|}{2}-1=-3$

Add 1 to both sides:

$\longmapsto$ $\frac{\left|m\right|}{2}-1+1=-3+1$

$\longmapsto$ $\frac{\left|m\right|}{2}=-2$

Multiply both sides by 2:

$\longmapsto$ $\frac{2\left|m\right|}{2}=2\left(-2\right)$

$\longmapsto$ $\left|m\right|=-4$

No solution!

A collection of 33 coins having dimes quarters and nickels, there are 3 times more nickels then dimes and half the amount of dim

zloy xaker [14]

Answer:

Each coins are quarters of 6, nickels of 18 and the dimes of 9.

Step-by-step explanation:

There is a mistake in question.

The question must be:

A collection of 33 coins having dimes quarters and nickels, there are 3 times as many nickels as quarters, and one-half as many dimes as nickels, all of the coins equal $3.30 how many coins of each kind are there?

Now, to find the number coins of each.

Let the quarters be $x$ .

Nickels be $3x$ .

And the dimes be $\frac{3x}{2}$ .

So, the total collection of coins are:

$x+3x+\frac{3x}{2} =33.$

On adding the fractions we get:

$\frac{2x+6x+3x}{2} =33$

$\frac{11x}{2} =33$

Multiplying both sides by 2 we get:

$11x=66$

Dividing both sides by 11 we get:

$x=6.$

Thus, quarters = 6.

Nickels = $3x=3\times 6=18.$

Dimes = $\frac{3x}{2} =\frac{3\times 6}{2} =\frac{18}{2}=9 .$

Therefore, each coins are quarters of 6, nickels of 18 and the dimes of 9.

What is the distance between the points (-4, 6) and (1, -6)?

Oksanka [162]

Answer:

The distance between these 2 points is 13.

Step-by-step explanation:

Picture the 2 points on a graph as a right triangle, where the hypotenuse of that right triangle is the distance between the points. It is very easy to find the length of the legs of that triangle, and you can use those legs to calculate the length of the hypotenuse.

First, find the vertical distance, or the distance between the y-coordinates. Either just look at a graph and count, or subtract them.

$-6-6=-12$

Distance is an absolute value from 0, so -12 is the same as 12.

Next, find the horizontal distance between the x-coordinates.

$1--4=5$

Now, we have the length of the legs, 5 and 12. Use the pythagorean theorem to find the length of the hypotenuse:

$a^2+b^2=c^2\\5^2+12^2=c^2\\25+144=c^2\\c^2=169\\c=\sqrt{169}\\c=13$

The distance between these 2 points is 13.
