GeometryThe diagonals of a kite are in the ratio of 3:2. The area of the kite is 27 cm^2 . Find the length of both diagonals. (Hint: Let the lengths of the diagonals be 3x and 2x)

How do I do this?

Answers

$A=27 \ cm^2 \n \n d_(1)=3x , \ \ d_(2) = 2x \n \n S=(1)/(2)\cdot d_(1)\cdot d_(2)\n \n27 = (1)/(2)\cdot 3x \cdot 2x \n \n 3x^2 = 27 \ \ /:3$

$x^2 = 9 \n \n3x=x=√(9)\n \nx=3 \ cm \n \n d_(1)=3x = 3*3 =9 \ cm \n \nd_(2)=2x=2*3 = 6 \ cm \n \n Answer : \n The \ length \ of \ the \ diagonal \ is: \ d_(1)= 9 \ cm \ and \ d_(2)= 6 \ cm$

Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 45 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 23 of the number of part 2 questions. What was the total number of questions on Stephanie's exam?

Answers

Given :

Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 4/5 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 2/3 of the number of part 2 questions.

To Find :

The total number of questions on Stephanie's exam.

Solution :

Let, number of questions in Part 1 is x :

$16=(4)/(5)x\n\nx=20$

Let, number of questions in Part 2 is y :

$16=(2)/(3)y\n\ny=24$

Therefore, total number of questions on Stephanie's exam are 20 + 40 = 60.

Hence, this is the required solution.

I need the answer for -3x-3=4x+3

Answers

Answer:

$\huge\boxed{x=-\frac{6}7}$

Step-by-step explanation:

To solve this problem, use the fact that you can perform any operation(with a few exceptions) to both sides of an equation, to isolate the variable.

Simply subtract 3 from both sides to get:

-3x - 3 - 3 = 4x + 3 - 3

-3x - 6 = 4x

Then add 3x to both sides to get:

-3x + 3x - 6 = 4x + 3x

-6 = 7x

Then divide both sides by 7 to get:

-6 / 7 = 7x / 7

-6/7 = x

$Answer :$ $(3x+9)/(4x+12) \n =3(x+3)/4(x+3) \n =3/4 \n (=0.75)$

Put common terms in evidence and simplify:

$\boxed{(3x+9)/(4x+12)=(3(x+3))/(4(x+3))=(3)/(4)}$
