Answer:

no solutions

Step-by-step explanation:

if you simplify the left side you will get 27z - 6 and the other side is 27z - 5

no value for 'z' will ever get these two expressions to equal each other because 6≠5

A 9 cm tall cone shaped paper cup can hold up to 58.9 cm cubed of water. What is the minimum amount of paper needed to make the

babymother [125]

Volume of a cone, V = πr^2h/3

r = Sqrt 3V/πh = Sqrt [(58.9*3)/(3.14*9)] = 2.5 cm, minimum

Surface area, A = πr [r+ Sqrt (h^2+r^2)] = 3.14*2.5*[2.5+ Sqrt (9^2+2.5^2)] = 92.95 cm^2

Therefore, minimum amount of paper required is 92.95 cm^2

What is the answer of the problem; <br> 3x-4+2(x-5)=9x+8-2x

alexgriva [62]

Answer:

The answer to the given problem $3x-4+2(x-5)=9x+8-2x$ is x=-11

Step-by-step explanation:

Given problem is $3x-4+2(x-5)=9x+8-2x$

To solve the equation:

$3x-4+2(x-5)=9x+8-2x$

$3x-4+2x-10=9x+8-2x$ (multiplying the term with factor)

$5x-4-10=7x+8$ (adding the like terms)

$5x-14=7x+8$ (adding the like terms)

Now taking the terms to one side

$5x-14-7x-8=0$

$-2x-22=0$ (adding the like terms)

$-2x=22$

$-x=\frac{22}{2}$

$-x=11$

x=-11

Therefore x=-11

The answer to the given problem $3x-4+2(x-5)=9x+8-2x$ is x=-11

Required equation in slope intercept form is: $y=5x+4$

Step-by-step explanation:

Given

Let m denote the slope of line

m = 5

the line passes though (1,9)

Slope-intercept form of equation of line is:

$y= mx+b$

Putting m=5 in the equation

$y = 5x+b$

Putting (1,9) in the equation

$9 = 5(1) +b\\9 = 5+b\\b = 9-5\\b = 4$

Putting the value of b

$y = 5x+4$

Hence,

Required equation in slope intercept form is: $y=5x+4$
