All you have to do is make the fraction of it which is 4/30. Then simplify to 2/15 which is your answer.

Two gardeners can do the weekly yard maintenance in 8 minutes if they work together. The older gardener takes 12 minutes more th

weqwewe [10]

Answer:

Let x be the time taken( in minutes ) by younger gardener,

So, the one minute work of younger gardener = $\frac{1}{x}$

Also, the time taken by older gardener = (x+12) minutes ( given ),

So, the one minute work of older gardener = $\frac{1}{x+12}$

Total work done in one minute = $\frac{1}{x}+\frac{1}{x+12}$

Now, total time taken = 8 minutes,

Total work done in one minute = $\frac{1}{8}$

Thus,

$\frac{1}{x}+\frac{1}{x+12}=\frac{1}{8}$

$\frac{x+12+x}{x^2+12x}=\frac{1}{8}$

$\frac{2x+12}{x^2+12x}=\frac{1}{8}$

$16x + 96 = x^2+12x$

$x^2 -4x -96=0$

$x^2 - 12x + 8x - 96=0$

$x(x-12) + 8(x-12)=0$

$(x+8)(x-12)=0$

By zero product product property,

x + 8 =0 or x - 12 =0

⇒ x = -8 ( not possible ), x = 12

Hence, the time taken by younger gardener = 12 minutes,

And, the time taken by older gardener = 12 + 12 = 24 minutes.

Whats the point of intersection between these two lines?<br><br>x+y=10<br>x+2y=14

Yakvenalex [24]

You have to make an equation that i forgot what was called but you just take
x+y=10 and multiply it by -2 so the y’s can cancel out

so you’ll end up with:

-2x-2y= -20
(+) x+2y=14

you’ll get : x = -6

then you plug in -6 for x, solve for y and your coordinates will be

(-6 , 10)
