If x and y vary directly and x=25 when y=100 find x when y=24.
PLEASE HELP FASTTTTTTT

Answers

Answer:

x = 6

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 25 when y = 100 , then

100 = 25k ( divide both sides by 25 )

4 = k

y = 4x ← equation of variation

When y = 24 , then

24 = 4x ( divide both sides by 4 )

6 = x

5 Which equation is equivalent to
3(2 x – 5) = 4( x + 3)?
A 2x= -27
B 2 x= 27
C 10 x=-27
D 10 x=-3

Answers

Answer:

I think its B

Step-by-step explanation:

Let's solve your equation step-by-step.

3(2x−5)=4(x+3)

Step 1: Simplify both sides of the equation.

3(2x−5)=4(x+3)

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

6x+−15=4x+12

6x−15=4x+12

Step 2: Subtract 4x from both sides.

6x−15−4x=4x+12−4x

2x−15=12

Step 3: Add 15 to both sides.

2x−15+15=12+15

2x=27

Step 4: Divide both sides by 2.

The equation is equivalent to given equation is 2x=27. Therefore, option B is the correct answer.

What is an equivalent equation?

Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.

The given equation is 3(2x-5)=4(x+3).

Now, 6x-15=4x+12

6x-4x=12+15

2x=27

The equation is equivalent to given equation is 2x=27. Therefore, option B is the correct answer.
