5x - 2y = 17

4x - 3y = 8

Try to change one of the equations to isolate a variable, so you can use the new equation and substitute it into the other equation.

5x - 2y = 17

-2y = 17 - 5x

y = -17/2 + 5/2x

Now plug this into the second equation

4x - 3(-17/2 + 5/2x) = 8

4x + 51/2 - 15/2x = 8

8/2x - 15/2x = 16/2 - 51/2

-7/2x = -35/2

x = 5

Plug this into either equation to find y

4x - 3y = 8

4(5) - 3y = 8

20 - 3y = 8

-3y = -12

y = 4


x = 5, y = 4

Riya is applying mulch to her garden. she applies it at a rate of 250 , 000 cm 3 250,000 cm 3 250, comma, 000, start text, space
Tatiana [17]

The rate in

\frac{ {m}^{3} }{ {m}^{2} }  \: is \:0.25\frac{ {m}^{3} }{ {m}^{2} }

<h3>How to find rate is riya applying mulch in m^3/m^2 ?</h3>

given that riya applies it at a rate of 250,000 cm^3 of mulch for every m^2 of garden space.

we already know that 1m = 100cm.

so, each side of this cube is 100cm in length.

so,100 \times 100 \times 100 \: {cm}^{3}  \: in \:  {m}^{3}

To find what is the volume in cubic metres.

\frac{250000}{10000000}  =  \frac{1}{4}  = 0.25 \frac{ {m}^{3} }{ { m}^{2} }

so, the rate is0.25 \frac{ {m}^{3} }{ {m}^{2} }

Alchen [17]

Answer:

Constant of proportionality is 12

The cost of buying new bicycle changes  12 dollar per week

Step-by-step explanation:

we are given

The equation as

d=12w

where

d represents the amount in dollars

w is number of weeks

now, we can compare it with

y=kx

where

k is constant of proportionality

we can compare

and we get

k=12

So,

Constant of proportionality is 12

we can see that

12=\frac{d}{w}

So,

The cost of buying new bicycle changes  12 dollar per week
