Answer:

x = 30

Step-by-step explanation:

The 2 angles lie on a straight line and sum to 180° , then

x - 3 + 153 = 180

x + 150 = 180 ( subtract 150 from both sides )

x = 30

Answer:

x = 30

Step-by-step explanation:

180° = total

153° = part

180° - 153° = 27°

Then use the equation to find the value of x

(x - 3) = 27

(x + 3) = +3 Add 3 to both sides!

x = 30

On Saturday morning , Owen earned $ 24 . By the end of the afternoon he had earned a total of $ 60 . Enter an equation , using x

Hatshy [7]

Owen earned $ 36 on Saturday afternoon

<em><u>Solution:</u></em>

Let "x" be the amount earned by Owen between morning and afternoon

On Saturday morning , Owen earned $ 24

By the end of the afternoon he had earned a total of $ 60

From given information,

Amount earned on saturday morning + Amount earned on saturday afternoon = Total money earned

Therefore,

24 + x = 60

x = 60 - 24

x = 36

Hence Owen earned $ 36 on Saturday afternoon

Write an equation of a line that has a y-intercept of 5 and passes through the point (-4,4)

mash [69]

Answer:

$\huge\boxed{y= \frac{1}{4}x+5}$

Step-by-step explanation:

In order to find the equation to this line, we have to note that with an incomplete equation, we can substitute in a point on the graph to find an unknown value.

The equation of a line is most commonly written in slope-intercept form, making it $y=mx+b$ , where m is the slope and b is the y-intercept.

We know the y-intercept, which is 5, so our equation is currently $y=mx+5$ .

We also know that the point (-4, 4) lies on this line. Therefore, we can plug it into our formula.

$4 = -4m + 5$
$-1= -4m$
$m = \frac{1}{4}$

This means that the slope of our line is $\frac{1}{4}$ . Plugging that into our equation as m makes the final equation

$y = \frac{1}{4}x + 5$ .

Hope this helped!
