What is the fraction for 45 divided by 20 please show work
lianna [129]

Answer:

9/4

Step-by-step explanation:

The divide symbol is also the line that separates the numerator and the denominator, so 45÷20 can also be written as 45/20.

We can see that both 45 and 20 are divisible by 5, so we can simplify the fraction down to 9x5/4x5, and then we cancel out the 5s and are left with 9/4

What is the equation in standard form of the line Y equals 1 / 9 x + 5
Juli2301 [7.4K]

Answer:

1/9x - y = -5

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Equality Properties

<u>Algebra I</u>

Standard Form: Ax + By = C

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define equation</u>

Slope-Intercept Form:   y = 1/9x + 5

<u>Step 2: Find Standard Form</u>

  1. Subtract 1/9x on both sides:                    -1/9x + y = 5
  2. Multiply -1 on both sides:                         1/9x - y = -5
