Answer:

3 students with red hair

12 students with brown hair

Step-by-step explanation:

1/6 times 18 = 18/6 = 3 students with red hair

4/6 times 18 = (18 times 4)/6= 12 students with brown hair

Answer:

Red=3

Brown=12

Step-by-step explanation:

So to find 1/6 of 18 you divide 18 by 6 which is 3.

red = 3

Then to find 4/6 well you've already found out 1/6 is 3 so all you need to do is times that by 4.

3x4=12

Brown = 12

In right triangle XYZ, triangle Y is the right angle and m angleX = 60 degrees. If YZ= 4 what is XY
Marina86 [1]

Answer:

XY = \frac{4\sqrt 3}{3}

Step-by-step explanation:

<em>The question is illustrated with the attached figure.</em>

Required

Determine XY

To solve for XY, we make use of the tan function, which states that:

tan\theta = \frac{Opposite}{Hypotenuse}

In this case:

tan\ 60= \frac{YZ}{XY}

Substitute 4 for YZ

tan\ 60= \frac{4}{XY}

Make XY the subject

XY= \frac{4}{tan\ 60}

tan\ 60 =\sqrt 3

So, the expression becomes:

XY = \frac{4}{\sqrt 3}

Rationalize:

XY = \frac{4 * \sqrt 3}{\sqrt 3 * \sqrt 3}

XY = \frac{4\sqrt 3}{3}

Solve this inequality for x: -46 -8x &gt;22.
olga2289 [7]

Answer:

Step-by-step explanation:

The key to answering this is to know that the only time you'll change the direction of the sign is when you multiply or divide by a negative number.

-46 - 8x > 22

-8x > 22 + 46

-8x > 68

x < 68/-8        (we divided by -8 so the inequality changed direction)

x < -17/2

Solve the equation <br>-88=2+2(5m-5)
const2013 [10]

-88 = 2 + 2(5m - 5)

Distribute 2 inside the parentheses.

-88 = 2 + 10m - 10

Combine like terms on the right side.

-88 = -8 + 10m

Add 8 to both sides.

-80 = 10m

Divide both sides by 10.

\boxed {m = -8}
