First line up and add together all of your whole numbers. 
7+8+4= 
Then add up all of your fractions. I like to set them up in columns one above the other. That way when you change the denominators you can see them easier.
looking at all the denominators we can see that they all have a 6 in common. So change them all to a 6, remember what you do to the bottom you have to do to the top. Multiply 2/3 top and bottom by a 2, Multiply 1/2 top and bottom by 3 and the last is 1/6 so you don't need to change that one. Now you can add all the tops together and end up with 8/6. This is improper divide the bottom into the top and you have 1 and 2/6 left over. This will reduce to 1 and 1/3. NOW go back and add this to the whole parts that you added up first. The final answer should be 20 and 1/3/

13. Oscar's dog house is shaped like a tent. The slanted sides are both 5 feet
VashaNatasha [74]

Answer:

The height of the dog house = 4 feet.

Step-by-step explanation:

Given:

The shape of the dog house is like a tent.

The slant heights of the house is 5 feet.

The bottom of the house is 6 feet across.

To find the height of the dog house at its tallest point.

Solution:

On drawing the figure of the dog house in the shape of a tent, we find out that the tallest point would be at the midpoint of the bottom of the house.

Thus, we ave a right triangle, of which one leg = \frac{6\ ft}{2}=3\ ft and hypotenuse = 5\ ft

<em>Applying Pythagorean theorem to find the measure of the other leg which is the height of the house.</em>

Hypotenuse^2=Leg1^2+Leg2^2

Plugging in values.

5^2=3^2+Leg2^2

25=9+Leg2^2

Subtracting both sides by 9.

25-9=9-9+Leg2^2

16=Leg2^2

Taking square root both sides.

\sqrt{16}=\sqrt{Leg2^2}

4=Leg2

Thus, the height of the dog house = 4 feet.

All angles on a triangle add up to 180. If it's a right triangle it would be set up like this: 90+3x-4=6x-5=180. You would subtract 90 from 180 and get 90 left. 3x-4+6x-5=90. Then you would add 5 and 4 to 90.....3x+6x=99. Then you add 3x and 6x then you would be left with 9x=99. Divide 99 by 9 and you get x=11.

Y=1/4x + 6<br> that passes through the point (-4, 3) in slope-intercept form.
Komok [63]

Answer:

The answer is

<h2>y =  \frac{1}{4} x + 4</h2>

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line.

The equation is

y = 1/4x + 6

Comparing with the general equation above

Slope = 1/4

Since the lines are parallel their slope are also the same

That's

Slope of parallel line = 1/4

So the equation of the parallel line using point (-4 , 3) and slope 1/4 is

<h3>y - 3 =  \frac{1}{4} (x + 4) \\ y - 3 =  \frac{1}{4} x + 1 \\ y =  \frac{1}{4} x + 1 + 3</h3>

We have the final answer as

<h3>y =  \frac{1}{4} x + 4</h3>

Hope this helps you
