Suppose x=0.5(300-x). what is the value of x?

Mathematics
1 answer:
Sonbull [250]3 years ago
6 0

Expand

x = 150 - 0.5x

Add 0.5x to both sides

x + 0.5x = 150

Simplify x + 0.5x to 1.5x

1.5x = 150

Divide both sides by 1.5

x = 150/1.5

Simplify 150/1.5 to 100

<u>x = 100</u>

 The regular rolls are     15x - 2y = 4

The vegetarian rolls   20x - 3y = 1


So the values are:

                           x = 2 and y = 13

The result is, 2 chefs and 13 customers.

   = (-1 -71)/(-100-7)

    = -72/-107

    = 72/107

If y=14 when x=8, find y when x=12

Answer:

12 pencils in each package.

Two expressions are shown below.
tankabanditka [31]

Answer:

0.25x -12= 18- 0.55x (subtract 0.25x from both sides)

-12= 18 -0.80x (subtract 18 from both sides)

-30= -0.80x (divide each side by -0.80)

x= 37.5 (this is your answer)
