Raj tried to solve the system below.
jekas [21]

Answer: Option C) Raj forgot the negative when substituting -15+9x for y.


Solution:

(1) 9x-y=15

(2) 2x+8y=28

Isolating y in the first equation. Subtracting 9x both sides of the equation:

(1) 9x-y-9x=15-9x

Subtracting:

(1) -y=15-9x

Multiplying both sides of the equation by -1:

(1) (-1)(-y)=(-1)(15-9x)

(1) y=-15+9x

Then Raj found the value of y. It's not option D.

Substitutng y by -15+9x in the second equation:

(2) 2x+8(-15+9x)=28

Then option C) is the answer: Raj forgot the negative when substituting -15+9x for y.

Eliminating the parentheses applying the distributive property in the multiplication:

(2) 2x-120+72x=28

Adding similar terms:

(2) 74x-120=28

Solving for x. Adding 120 both sides of the equation:

(2) 74x-120+120=28+120

Adding:

(2) 74x=148

Dividing both sides of the equation by 74:

(2) 74x/74=148/74

Dividing:

(2) x=2

Solving for y: Replacing x by 2 in the first equation:

(1) y=-15+9x

(1) y=-15+9(2)

Multiplying:

(1) y=-15+18

Subtracting:

(1) y=3

∆ABC is a right angled at B and D is a point on BC if AD = 18cm BD = 9cm and CD =4cm Find AC
Gemiola [76]

In triangle, ABD,

AD²= AB²+BD²

AB² = AD²-BD²

AB² = 18²-9² = 324-81 = 243

AB = √243

In triangle, ABC,

AC² = AB²+BC²

AC² = (√243)²+(13)²

AC² = 243+169

AC = √412

AC = 20.29

3x +15 = 2x + 10 + x + 5
Shkiper50 [21]

Answer:

The equation is true.

Step-by-step explanation:

Simplify. Combine like terms:

3x + 15 = (2x + x) + (10 + 5)

3x + 15 = (3x) + 15

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:

3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)

3x - 3x = 15 - 15

0 = 0

~ True. The two expressions are equal to each other.

The base of a triangle is 2ft The height of the triangle is 15 in what is the area of the triangle in square inches
Yakvenalex [24]

Answer:

Area of a triangle = A = 180in^{2}

Step-by-step explanation:

Given Data:  

height of a triangle = h = 15 in

base of a triangle = b = 2 feet  = 2*12 =24 in

To Find Out:  

Area of a triangle = A = ?  

Formula:  

Area of a triangle = A =  \frac{1}{2} (b*h)

Solution:  

Area of a triangle = A =  \frac{1}{2} (b*h)

Area of a triangle  = A =  \frac{1}{2} (24*15)

Area of a triangle  = A =  \frac{1}{2} (360)

Area of a triangle = A = 180in^{2}
