What does x equal in this equation: 24+3x=3x+3(7-1) Please help this is due tomorrow!

Answers

Answer 1

Answer:
      24 + 3x = 3x + 3(7 - 1)

Eliminate the parentheses: 24 + 3x = 3x + 3(6)

      24 + 3x = 3x + 18

Subtract 3x from each side:    24 = 18

Look at that for a second. Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.

That's just another way to say: "The equation has NO solution."

Which system of equations can be used to find the roots of the equation 4x2x2+2x?

Answers

Answer:

$x=0$ and $2x+1=0$

Step-by-step explanation:

We are given that an equation

$4x^2+2x$

We have to find the system of equation which can be used to find the roots of the given equation.

$2x* 2x+2x$

Taking 2 x common then we get

$2x(2x+1)$

$2x(2x+1)=0$

$2x=0$ and $2x+1=0$

$x=0$ and $2x+1=0$

$2x=-1$

$x=-(1)/(2)$

Hence, the system of equations which can be used to find the roots of the equation is given by

$x=0$ and $2x+1=0$

mark wants to paint a mural. He has 1 1/3 gallons of yellow paint, 1 1/4 gallons of green paint, and 7/8 gallon of blue paint. mark plans to use 3/4 of each paint color. how many gallons of paint will he have left after painting the mural

Answers

we have

Yellow paint

$1(1)/(3) =(3*1+1)/3\n \n =(4)/(3) gal$

Find the
amount of yellow paint left after painting the mural

$((4)/(3) -(3)/(4) )=(4*4-3*3)/12\n \n =(7)/(12) gal$

Green paint

$1(1)/(4) =(4*1+1)/4\n \n =(5)/(4) gal$

Find the
amount of green paint left after painting the mural

$((5)/(4) -(3)/(4) )=(5-3)/4\n \n =(2)/(4) gal$

Blue paint

$(7)/(8)gal$

Find the
amount of blue paint left after painting the mural

$((7)/(8) -(3)/(4) )=(7-2*3)/8\n \n =(1)/(8) gal$

Find the
total amount of paint left after painting the mural

$(7)/(12) +(2)/(4) +(1)/(8) =((2*7+6*2+3*1))/(24) \n \n =(29)/(24) gal$

$(29)/(24) =1(5)/(24) gal$

therefore

the answer is

$1(5)/(24) gal$

Mark has: 1 1/3 = 4/3 gallons of Yellow
   1 1/4 = 5/4 gallons of Green
      7/8 gallons of Blue.

Total = (4/3 + 5/4 + 7/8) LCM = 24
      = (32 + 30 + 21)/24 = 83/24 Gallons of Paint in total.

If he used 3/4 of each, he would have (1 - 3/4) = 1/4 of each left.

Therefore gallons left = 1/4 * (83/24) = 83/96 gallons left.
   = 0. 8646 gallons left in total.
