Use the Distributive Property to solve the equation. 3x-5(x-4)=-9+5x+15
Norma-Jean [14]

Answer:

I keep getting no solution

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(x−4)=−9+5x+15

(5)(x)+(5)(−4)=−9+5x+15(Distribute)

5x+−20=−9+5x+15

5x−20=(5x)+(−9+15)(Combine Like Terms)

5x−20=5x+6

5x−20=5x+6

Step 2: Subtract 5x from both sides.

5x−20−5x=5x+6−5x

−20=6

Step 3: Add 20 to both sides.

−20+20=6+20

0=26

The reciprocal of 2/3 is 3/2. If the reciprocal of 4x/5 is 1/20, what is x?
Black_prince [1.1K]

Since 4x/5 is the reciprocal of 1/20, that means that 4x/5 = 20/1, or 20. Using this info, we can form the equation \frac{4x}{5}=20 . From there we can solve for x.

Firstly, multiply both sides by 5: 4x=100

Next, divide both sides by 4 and your answer will be x=25
