What is the area of the triangle?

48 in 2
28 in 2
96 in 2
24 in 2

Answers

Answer:

48 in^2

Step-by-step explanation:

To find the area of a triangle is (1/2)*base*height, so (1/2)*4in*24in = 2in*24in = 48 in^2.

Answer:

48 in2

Step-by-step explanation:

when finding area we use the equation A= 1/2bh

b meaning base and h meaning height

so for this we would use A= 1/2(24)(4)

multiply them both to get A=1/2(96)

and then take half of 96 to get 48

so the answer is 48in 2

Answer:

x=4

Step-by-step explanation:

Hope this helps!

Plz, mark brainiest! ^.^

Answer:

x = 4

Step-by-step explanation:

Use the distributive property to distribute the -3 amongst the 2x and the -3 in the parenthesis. Once distributed you should have -6x + 9 = -5x + 5. Next, you want to get all like terms on the same side, and to do that you must swap the +9 and the -5x. When you swap these, you must 'flip' the sign and change 9 to -9 and -5x to 5x. Now the equation should look like this: -6x + 5x = -9 + 5.

Now just solve. After solving, it should look like this: -1x = -4. Now to get rid of the negatives. Just divide each side by negative one and your answer is x = 4.

Two systems of equations are shown below:

System A
System B
3x + 2y = 3
−x − 14y = 1
−2x − 8y = −1
−2x − 8y = −1


Which of the following statements is correct about the two systems of equations? (1 point)

The value of x for System B will be one−third of the value of x for System A because the coefficient of x in the first equation of System B is one third times the coefficient of x in the first equation of System A.
The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding −4 to the first equation of System A and the second equations are identical.
They will have the same solution because they represent the same lines when plotted on the coordinate axes.
They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.

Answers

Answer:

The two linear equations represented in system A as :

3 x + 2 y =3   -------(1)

- 2 x - 8 y = -1  ------(2)

(1) × 2 + (2) × 3 gives

⇒ 6 x + 4 y - 6 x - 24 y = 6 -3

⇒ - 20 y = 3

⇒ y =

Putting the value of y in equation (1), we get

Two linear equation represented in system B is:

3.   -x - 14 y =1

4.   - 2 x - 8 y = -1

-2 ×Equation (3) + Equation (4)=

2 x +28 y- 2 x - 8 y= -2 -1

⇒ 20 y = -3

⇒y =

Putting the value of y in equation (3),we get

As Two system , that is system (A) and System (B) has same solution.

By looking at all the options , i found that Option (D) is correct. The two system will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.

A department store sells a pair of shoes with an 87% markup. If the store sells the shoes for $193.21 then what is their non-markup price?

Answers

Step-by-step explanation:

87% + 100% = 187%

187% of original price = $193.21

100% of original price = $193.21 * (100/187) = $103.32.

The non-markup price is $103.32.

Answer:

87% + 100% = 187%

187% of original price = $193.21

100% of original price = $193.21 * (100/187) = $103.32.

The non-markup price is $103.32.
