Answer:

32.8

Step-by-step explanation:

The average is calculated as

average = \frac{sum}{count}

let x be the fourth number, then

\frac{24.2+14.5+50.5+x}{4} = 30.5 ( multiply both sides by 4 )

89.2 + x = 122 ( subtract 89.2 from both sides )

x = 32.8

Thus the fourth number is 32.8

Helaine graphed the equation 12x – 4y = 3. What was the slope of Helaine’s line?\
Bess [88]

Answer:

\large\boxed{\text{The slope}\ m=3}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

We have the equation of a line in the standard form:

12x-4y=3

Convert to the slope-intercept form:

12x-4y=3         <em>subtract 12x from both sides</em>

-4y=-12x+3        <em>divide both sides by (-4)</em>

y=\dfrac{-12}{-4}x+\dfrac{3}{-4}\\\\y=3x-\dfrac{3}{4}
