Answer:

x = 20

Step-by-step explanation:

The formula for the area of a triangle is

Area = 1/2 Base * Height

To find out what x is, plug the numbers in the formula

600 = 1/2 5x * 12

Multiply 5x by 12

600 = 1/2 60x

Multiply 1/2 by 60x

600 = 30x

Divide by 30

20 = x

To see if this is correct, plug it in again..

600 = 1/2 5(20) * 12

Simplify 5(20)

600 = 1/2 100 * 12

Multiply 12 by 100

600 = 1/2 1200

Multiply by 1/2

600 = 600

x is equal to 20

X has to be 20 because 12 times 5 is 60 am and because it is a right triangle it is half the value so 20 times 30 is 600.

Find the value of x in the equation 3(2x-4)-5(x-2)=1

Lyrx [107]

Answer:

x=3

Step-by-step explanation:

3(2x−4)−5(x−2)=1

Step 1: Simplify both sides of the equation.

3(2x−4)−5(x−2)=1

(3)(2x)+(3)(−4)+(−5)(x)+(−5)(−2)=1(Distribute)

6x+−12+−5x+10=1

(6x+−5x)+(−12+10)=1(Combine Like Terms)

x+−2=1

x−2=1

Step 2: Add 2 to both sides.

x−2+2=1+2

x=3

State if the two triangles are congruent. If they are, prove by using a two column proof!!!

Goshia [24]

Answer:

Step-by-step explanation:

There are four axioms to prove the triangles are contruent.They are

SSS(side side side axiom)

SAS(side angle side axiom)

AAS(angle angle side axiom)

ASA(angle side angle axiom)

RHS (right angle hypotenuse side axiom)

here two triangles are congruent by RHS axiom

Solve each system of equations by writing a new system that eliminates one of the variables.

Rufina [12.5K]

Answer:

$x=33\\y=-41$

Step-by-step explanation:

Let:

$2x+y=25\hspace{5}(1)\\and\\4x+3y=9\hspace{5}(2)$

We need to eliminate one of the variables, so let's use elimination method. First multiply (1) by 2

$2*(1)\equiv\hspace{5}4x+2y=50$

Now subtract (2) from 2*(1) in order to eliminate x:

$2*(1)-(2)\\4x-4x+2y-3y=50-9\\-y=41$

Solving for y:

Multiplying both sides by -1

$y=-41$

Finally, replacing the value of y in (1)

$2x-41=25$

Solving for x:

add 41 to both sides:

$2x=66$

Multiply both sides by 1/2:

$x=\frac{66}{2} =33$
