If you expand the left hand sign, the equation becomes

$3x-6 = 3x-2$

This means that the term $3x$ cancels out, since it appears in both sides. So, we're left with

$-6=-2$

which is clearly false, i.e. it leads to an impossible equation, which thus have no solutions.

A number is greater than 50 and less than 85 the number has 13 and 3 as factors

alina1380 [7]

Answer:

The Answer is: 78.

Step-by-step explanation:

This one makes you think!

Let n = the number.

The number is greater than 50 and less than 85:

50 < n < 85

Some of the factors are 13 and 3.

So, multiply 13 * 3 = 39.

Multiply again by 2:

39 * 2 = 78.

78 can be factored as:

13 * 3 * 2 = 78, and it is greater than 50 and less than 85.

The number is 78.

Hope this helps! Have an Awesome Day!! :-)

In ΔWXY, the measure of ∠Y=90°, YX = 40, XW = 41, and WY = 9. What ratio represents the cosine of ∠W?

andreyandreev [35.5K]

Answer:

$\cos(W) = \frac{9}{41}$

Step-by-step explanation:

Given

$\angle Y = 90^o$

$YX = 40; XW = 41; WY = 9$

Required

Determine $\cos(W)$

The question is illustrated with the attached image.

So:

$\cos(W) = \frac{Adajacent}{Hypotenuse}$

$\cos(W) = \frac{WY}{XW}$

This gives:

$\cos(W) = \frac{9}{41}$

Richard wants to make a garden with a perimeter of 16 feet, and length of 4 feet. He solves for the width by subtracting 8 from

Ostrovityanka [42]

The equation that can be used to solve this is:

$P =2W+2L\\OR\\P-2L = 2W\\\frac{P-2L}{2} = W$

Further explanation:

Let

$P\ be\ the\ perimeter\\L\ be\ the\ width\\W\ be\ the\ width$

The equation for the perimeter will be:

$P =2W+2L$

Given

P = 16 feet

L = 4 feet

W = ?

Putting the values in the perimeter formula

$16=2(4)+2W\\16=8+2W\\16-8= 2L\\8=2L\\L=\frac{8}{2}\\L=4\ feet$

The equation that can be used to solve this is:

$P =2W+2L\\OR\\P-2L = 2W\\\frac{P-2L}{2} = W$
