Solve for h. -18+7h>12+9h

Mathematics
1 answer:
Evgen [1.6K]4 years ago
4 0

Answer:

h

Step-by-step explanation:

-18+7h>12+9h

Add 18 to both sides:

-18+7h+18>12+9h+18

7h>9h+30

Subtract 9h from both sides:

7h>9h+30

-2h>30

Multiply both sides by -1 and flip the symbol:

\left(-2h\right)\left(-1\right)

2h

Divide both sides by 2:

\frac{2h}{2}

h

two sides of a triangle have the same length. the third side measures 6 m less than twice the common length. the perimeter of th
Y_Kistochka [10]

Let x be the length of the two sides that are the same.

Then the third side would be 2x -3.

The perimeter of the triangle will come from adding all of the sides together and setting it equal to the value given, 13.

That is,

x + x + (2x - 3) = 13

-- > 4x - 3 =13

-- > 4x = 16

-- > x = 4.

As for the answer, the question was cut short, but with x=4,,

the length of each of the common sides is 4, making the third side 5, to get a total perimeter of 13.

<h3>What are two sides of a triangle?</h3>

The hypotenuse of a right-angled triangle is its longest side, the base is its lower side, and the perpendicular, which stands next to the right angle, is its standing line.

You may determine the sides of a right-angled triangle using a number of techniques, such as the Pythagoras theorem or the triangle's perimeter.

Please answer! this is an important exam that im taking right now.

Answer:

Required ordered pair is (0,0) for system of equation

Step-by-step explanation:

The given system of equation is

A). 9^{12x} = 9^{3y}

B). y^{4} - 9y^{2} x^{2} =16y

On simplifying the equation A

9^{12x} = 9^{3y}

Take log on both side,

(12x) (log9) = (3y) (log9)

4x=y

To find the solution of the system of the equation :

Replacing value of y=4x in equation B,

y^{4} - 9y^{2} x^{2} =16y

(4x)^{4} - 9(4x)^{2} x^{2} =16(4x)

256x^{4} - 144x^{2} x^{2} =64x

256x^{4} - 144x^{4}=64x

112x^{4}=64x

We get,

x=0 and x=0.829

Since, 0.829 is not integer number

Only solution of equations is x=0

For the value of y

Replace value x in y=4x=0

Thus, Required ordered pair is (0,0)
