The value of x is 46/9.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

When both sides of an equation are same then the equation has infinitely many solutions.

We have been given equation as;

3x - 3(4 + x) = 3/4(3x + 2) - 1

LEts simplify the both hand side.

3x - 12 + -3x = 9x/4 + 3/2 - 1

12 = 9x/4 + 1/2

12 - 1/2 = 9x/4

Simplify;

23/2 = 9x /4

23(2) / 9 = x

x = 46/9

Hence, the value of x is 46/9.

What are the domain and range of the function f(x)=-log(5-x)+9?

Setler [38]

Answer:

Domain: x < 5

Range: all numbers, -∞, ∞

This is because the problem will be able to be solved with multiple solutions as long as there are no specific values assigned to <em>x. </em>The problem will have a solution from a range of negative infinity to infinity, meaning every number or solution you can think of.

What is 32986538537 plus 78.9 times 5

Umnica [9.8K]

Answer:

164,932,693,079.5

What is the mean of this data set? {14, 7, 2, 8, 3} Enter your answer as a decimal in the box.

Assoli18 [71]

The mean of the data set is 6.8.

Mean is the average value of the given set of observations. In statistics, we also come across different types of mean such as Arithmetic, Geometric and Harmonic mean.

Given

The data set is 14, 7, 2, 8, 3.

The mean of the data set is given by;

$\rm Mean = \dfrac{Sum \ of \ all \ data}{Number \ of \ data}\\\\Mean =\dfrac{14+7+2+8+3}{5}\\\\Mean = \dfrac{34}{5}\\\\Mean=6.8$

Hence, the mean of the data set is 6.8.

A hall measures 12 metres long,

Ilya [14]

$\huge\sf\red{Answer : - }$

<h2>Given :- </h2>

Length of the hall = 12m

wide of the hall (Breadth) = 10m

Height of the hall = 4m

Surface area of the walls (Four walls area)

<h2>Formula :- </h2>

Four walls area of the hall = 2h(l+b)

where,

h = height

l = length

b = breadth

<h2>Solution : - </h2>

By substituting values according to the formula,

➙ 2 × 4m(12m + 10m)

➙ 8m(22m)

➠ 176m²

It's option B

<h3><u>Hence, The surface area of the walls is (B) 176m²</u></h3>
