48 = 2(2w)+(4+2w)2. What Is w

crimeas [40]

Hello from MrBillDoesMath!

Answer:

w = 5

Discussion:

48 = 2 (2w) + (4 + 2w)2 =>

48 = 4w + 4*2 + (2w)*2 =>

48 = 4w + 8 + 4w => as 4w + 4w = 8w

48 = 8w + 8 => subtracting 8 from each side

48 - 8 = 8w => divide both sides by 8

(48 -8 )/8 = w =>

40/8 = w =>

w = 5 =>

Check: 2(10) + ( 4 + 2*5)*2 = 20 + 14*2 = 20 + 28 = 48

Thank you,

MrB

5x – 12y – 17 = 0<br> 1*9(x + 2) - (y + 1) + 3 = 0

valentina_108 [34]

Answer: $x=\frac{12y+17}{5}$

$y=\frac{-5x+17}{-12}$

$x=\frac{y-20}{9}$

y=9x+20

Step-by-step explanation:

5x-12y-17=0 (plus 17 from both sides)

5x-12y=17 (plus 12y from both sides)

5x=12y+17 (divide 5 from everything)

$x=\frac{12y+17}{5}$

5x-12y-17=0 (plus 17 from both sides)

5x-12y=17 (minus 5x from both sides)

-12y=-5x+17 (divide everything by -12)

$y=\frac{-5x+17}{-12}$

1*9(x+2)-(y+1)+3=0 (distribute 9 to x and to 2) (distribute -1 to y and to 1)

1*9x+18-y-1+3=0 (times 9x by 1)

9x+18-y-1+3=0 (combine like terms)

9x-y+20=0 (minus 20 from both sides)

9x-y=-20 (plus y to both sides)

9x=y-20 (divide 9 from both sides)

$x=\frac{y-20}{9}$

1*9(x+2)-(y+1)+3=0 (distribute 9 to x and to 2) (distribute -1 to y and to 1)

1*9x+18-y-1+3=0 (times 9x by 1)

9x+18-y-1+3=0 (combine like terms)

9x-y+20=0 (minus 20 from both sides)

9x-y=-20 (minus 9x from both sides)

-y=-9x-20 (divide -1 from everything)

y=9x+20

If six times a number is decreased by fourteen, the result is 124. What is the number

denis23 [38]

Answer:

$\large\boxed{23}$

Step-by-step explanation:

Six times a number is decreased by fourteen, the result is 124.

Write an equation that represents this

(6 * x) - 14 = 124

Multiply 6 by x to remove the parenthesis

6x - 14 = 124

Add 14 to both sides of the equation

6x = 138

Divide both sides of the equation by 6

x = 23

The unknown number is $\large\boxed{23}$

Hope this helps :)
