Answer:

Ralph's age now is 12 years

Step-by-step explanation:

This problem bothers on word problem

Step one

Let us begin by stating The problem Mathematically

Let Sara's age be x

1. Ralph is 3 times Sara's age =3x

2. In 4 year's time Ralph will be twice Sara's age

I.e 3x+4= 2x

Let's solve for Sara's age

3x+4= 2x

3x-2x=-4

x=-4

Since it is age we can't have a negative symbol

x+4

To find Ralph's age we use statement 1

Ralph is 3 times Sara's age

3x= 3(4)= 12

Hence Ralph is 12 years old currently

Point L is on line segment KM. Given LM=11 and KL=4, determine the length KM.
Scorpion4ik [409]

Hey there! I'm happy to help.

Let's think of the line segment KM as a road. It starts at point K and ends at M. You start driving from point K and after 4 miles, you have reached point L. The segment KL is equal to 4 because the distance between K and L is 4.

From point L to point M, you drive 11 miles. You are now at the end of the road. We want to find out how long the road is.

From point K to point L, you drove for 4 miles.

Then, from L to M, you drove 11.

We combine these...

11+4=15

The length of KM is 15.

Have a wonderful day! :D

(1/x-2)-(1/x+2)=
Karo-lina-s [1.5K]

\dfrac{1}{x-2}-\dfrac{1}{x+2}=\dfrac{x+2}{(x-2)(x+2)}-\dfrac{x-2}{(x-2)(x+2)}\\\\=\dfrac{(x+2)-(x-2)}{(x-2)(x+2)}=\dfrac{x+2-x+2}{(x-2)(x+2)}=\dfrac{4}{x^2-4}\to(D)

Used: a^2-b^2=(a-b)(a+b)

Answer: (D)=(4/x^(2)-4)
