Answer:

x = 3/5

Step-by-step explanation:

5x+4=7

Subtract 4 from each side

5x+4-4=7-4

5x = 3

Divide each side by 5

5x/5=3/5

x = 3/5

Reduce to the lowest terms<br> 1. 4x^3 y^4 / -8xy^2 <br> 2. 3m^2-3n^2 / 6m+6n
lawyer [7]
1.
\dfrac{4x^{3}y^{4}}{-8xy^{2}}=\dfrac{4}{-8}\cdot x^{3-1}y^{4-2}=\dfrac{-x^{2}y^{2}}{2}

2.
\dfrac{3m^{2}-3n^{2}}{6m+6n}=\dfrac{3}{6}\cdot \dfrac{(m+n)(m-n)}{m+n}=\dfrac{m-n}{2}

If c+1/d=5 , what is the value of 30d/2c+2
klemol [59]

Answer:

3

d\in R,\hspace{5}d\neq 0

Step-by-step explanation:

You can solve for any variable. From the first equation, let's solve for c :

\frac{c+1}{d} =5\\\\c+1=5d\\\\c=5d-1

Now, replace the value of c into the other equation:

\frac{30d}{2c+2} \\\\\frac{30d}{2(5d-1)+2} \\

Using distributive property

\frac{30d}{10d-2+2} =\frac{30d}{10d} =3

However, keep in mind that this is true for:

d\in R,\hspace{5}d\neq 0

Find the volume of a cone with a diameter of 12 m and a height of 5 m.
AnnZ [28]

Answer:

60\pi m³

Step-by-step explanation:

Use the cone volume formula, V = \pir²\frac{h}{3}

If the diameter is 12 m, the radius will be 6 m.

Plug in the height and radius into the formula, and solve:

V = \pir²\frac{h}{3}

V = \pi(6²)\frac{5}{y}

V = \pi(36)\frac{5}{3}

V = 60\pi

So, the volume of the cone is 60\pi m³
