Answer:

The answer should be M = 5/9(R - 21)

Step-by-step explanation:

To find this value, follow the order of operations to isolate M.

R = 9/5M + 21

R - 21 = 9/5M

5/9(R - 21) = M

(−14x^3y^3+4x^5 y6)÷(2x^4y^5)

valkas [14]

( - 14x^3)(y^3) + 4x^5y^6)/(2x^4y^5)

= 4x^5y^6 - 14x^3y^3/2x^4y^5

= 4x^2y^3 - 14/2xy^2

= 2x^2y^3 - 7/xy^2

Answer: 2x^2y^3 - 7/xy^2

Hope that helps!!!!

The amount of caffeine consumed from a glass of Diet Pepsi is proportional to the number of ounces that was drank. The table bel

Vilka [71]

Answer:

Constant of proportionality: $k=3$

Equation: $c=3d$

Step-by-step explanation:

By definition, Direct proportion equations have the following form:

$y=kx$

Where "k" is the Constant of proportionality.

In this case, let be "c" the the amount of caffeine consumed (in mg) from a glass of Diet Pepsi and "d" the number of ounces that was drank.

So, the equation that represents this relationship will have this form:

$c=kd$

Then, the first step is to find the Constant of proportionality "k".

Knowing that:

$c=24;d=8$

We can substitute values into the equation:

$24=k(8)$

Now, solving for "k", we get:

$\frac{24}{8}=k\\\\k=3$

Therefore, we can write the following equation that represents that proportional relationship:

$c=3d$

Cho tam giác ABC cân tại A trung tuyến AM.Biết BC=6cm,AM=4cm .Tính độ dài các cạnh AB và AC

abruzzese [7]

Vì tam giác ABC cân tại A (gt) mà AM là đg trung tuyến nên AM đồng thời là đg cao của t/giác đó:

AM là trung tuyến của t/giác ABC nên M là trung điểm BC:

=> BM =BC/2 =6:2=3(cm)

Xét tam giác AMB vuông tại M

AB^2 =AM^2+BM^2 ( theo định lý Py-ta -go)
