Answer:

  7x +18y = -5

Step-by-step explanation:

The slope is ...

  m = (y2 -y1)/(x2 -x1)

  m = (-2/3 -1/2)/(1 -(-2)) = (-7/6)/(3) = -7/18

The y-intercept is ...

  b = y -mx

  b = 1/2 -(-7/18)(-2) = 1/2 -7/9 = -5/18

Then the slope-intercept form of the equation is ...

  y = -7/18x -5/18

Multiplying by 18 and adding the opposite of the x-term gives the equation in standard form. The standard form equation is ...

  7x +18y = -5

Tara has ¾ cup of ice cream. How many ⅕ cup servings are in ¾ cup of ice cream?
My name is Ann [436]

Answer:

3 3/4

Step-by-step explanation:

3/4 * 1/5

First you would turn 1/5 into a reciprocal

Now your equation would be 3/4 *5/1

Now you multiply 3/4 * 5/1

15/4

Now find 15/4 as a mixed number

15/4 as a mixed number would be 3 3/4

Therefore there are 3 3/4 1/2 cup servings in a 3/4 cup of ice
