Answer:

144 sweets

Step-by-step explanation:

Let

x----> number of sweets that Dan has

y----> number of sweets that Gordon has

z----> number of sweets that Malachy has

we know that

x=48

x/y=4/3----> y/x=3/4 ----> y=(3/4)x

Substitute the value of x

y=(3/4)48=36

x/z=4/5 ----> z/x=5/4 ----> z=(5/4)x

Substitute the value of x

z=(5/4)48=60

therefore

altogether there are x+y+z=48+36+60=144 sweets

Line n passes through the points (-3,-7.5) and (2,-5). Thalia determined that the equation of the line n is y=0.5x. Explain the

yKpoI14uk [10]

<h3>The error is -6 </h3>

Step-by-step explanation:

If a line passes through the points $(x_1,y_1)$ and $(x_2,y_2)$

Then the equation of line is

$\frac{x- x_1}{x_1-x_2} =\frac{y-y_1}{y_1-y_2}$

Here given points are (-3,-7.5) and (2,-5)

Then the equation of the line is

$\frac{x+3}{-3-2} =\frac{y+7.5}{-7.5+5}$

⇔ $\frac{x+3}{-5} =\frac{y+7.5}{-2.5}$

⇔2.5(x+3) = 5(y+7.5)

⇔(x+3)= 2(y+7.5)

⇔x+ 3 = 2y +15

⇔2y = x+3-15

⇔y = $\frac{x-12}{2}$

⇔y = 0.5 x -6

The error is -6
