X - the number

x+\frac{1}{3}x+\frac{1}{8}x=70 \\
\frac{24}{24}x+\frac{8}{24}x+\frac{3}{24}x=70 \\
\frac{35}{24}x=70 \\
x=70 \times \frac{24}{35} \\
x=2 \times 24 \\
x=48

The number is 48.

A) Write the following in standard form and find A, B and C
alex41 [277]

Answer:

  • a)  2x -y = -5; A=2, B=-1, C=-5
  • b)  y = 2x +5

Step-by-step explanation:

a) Standard Form is ...

  Ax + By = C

where A > 0 and A, B, C are mutually prime.

To get that form, we can add 2x-5 to both sides of the equation:

  (2x -5) -2x = (2x -5) -y +5

  -5 = 2x -y

Then we can swap sides of the equal sign:

  2x -y = -5 . . . . . . standard form

Matching this to the generic standard form equation, we find ...

  A = 2

  B = -1

  C = -5

__

b) We can solve for y by adding 2x+y to both sides of the equation:

  (2x +y) -2x = (2x +y) -y +5

  y = 2x +5 . . . . . . slope-intercept form
