Answer:

a*(1 -0.5)*(1 +0.5) = 0.75a . . . . the original number "a" is larger

(a/(0.75a) -1) * 100% = 33 1/3% . . . . the original number is larger by 33 1/3% of the revised number

Answer:

  • a is larger by 33.33%

Step-by-step explanation:

Initial number = a

<u>Decrease by 50% </u>

  • a - 50% =
  • a - 0.5a =
  • 0.5a

<u>Increase by 50%</u>

  • 0.5a + 50% =
  • 0.5a + 0.5*0.5a =
  • 0.75a

<u>The difference between the initial and final numbers:</u>

  • a - 0.75a = 0.25a

<u>Percent difference:</u>

  • (0.25a/0.75a)*100% = 33.33%

Solve this equation -3x+1+10x=x+4
Salsk061 [2.6K]

Answer: x=\frac{1}{2}

Explanation:

We have been given with the equation -3x+1+10x=x+4

We will collect the terms that are written in variable of x in one side and the constant values on the other side we will get

-3x+10x-x=4-1

After simplification we will get  6x=3

which implies x=1/2

When x from right hand side shift  will shift to left hand side it will change its sign and similarly when 1 from left hand side shift to right hand side change its sign.

Therefore, x=1/2
