$520 was earned by carl in last week

Step-by-step explanation:

(1/2 X - 20 )  = 240

1/2 X = 240 +20 = 260

1/2 X = 240 +20 = 260

 X = 260÷1/2 = 520

X = 260÷1/2 = 520

verification

520 ÷2 = 260 - 20 = 240

520 ÷2 = 260 - 20 = 240

Hence proved

Which equation correctly represents the distance between −15.1 and −3.9 on a number line?
Korvikt [17]

Here what we observe

  • -3.9>-15.1

So as we know about subtracting lowest number is subtracted from highest no

So here

\\ \tt\longmapsto -3.9-(-15.1)=|-11.2|=11.2

Distance must be positive

Answer:

  x-intercept: (4, 0)

  y-intercept: (0, 3)

Step-by-step explanation:

The intercepts of the equation can be found by setting each variable to zero and solving for the other. The graph will be a line through the intercept points.

<h3>Intercepts</h3>

Setting x=0 and solving for y, we have ...

  4y -12 = 0   ⇒   y = 12/4 = 3

Setting y=0 and solving for x, we have ...

  3x -12 = 0   ⇒   x = 12/3 = 4

The intercepts are ...

  x-intercept: (4, 0)

  y-intercept: (0, 3)

<h3>Graph</h3>

The line will go through these intercept points.
