<h2>B) one solution</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • linear equation
  • PEMDAS
<h3>tips and formulas:</h3>
  • \sf\text{a system of linear equation has only one solution if $\frac{a_1}{a_2}\neq \frac{b_1}{b_2}$}
<h3>given:</h3>
  • \begin{cases}2x - 4y =  - 1 \\ 8x - 11y =  - 19 \end{cases}
<h3>let's solve:</h3>

  1. \sf substitute \: the \: value \: of \: a \: b :  \\  \frac{2}{8}   \ne  \frac{ - 4}{ - 11}  \\

\text{$\therefore$ the system of linear equation has only one solution}

What is 7/2 as a mixed number ​
kompoz [17]

Hello! :)

Answer:

\huge\boxed{3\frac{1}{2}}

\frac{7}{2} as a mixed number:

Divide 2 from 7 and find the remainder:

7 ÷ 2 = 3 R 1.

An improper fraction in mixed form has the quotient as the coefficient, and the remainder over the fraction. Therefore:

\frac{7}{2} = 3\frac{1}{2}

Find the length of the diagonal of a square with perimeter of 24
julsineya [31]

Answer:

d = 6sqrt(2) or 8.4853

Step-by-step explanation:

<u><em>Formula</em></u>

P = 4*s

s^2 + s^2 = d^2 where d is the diagonal and s is the side.

<u><em>Givens</em></u>

P = 24

<u><em>Solution</em></u>

P = 4s         Substitute for s

24 = 4*s      Divide by 4

24/4 = s

s = 6

================

d^2 = s^2 + s^2

d^2 = 6^2 + 6^2

d^2 = 36 + 26

d^2 = 72

d = sqrt(72)

Factors of 72

72: 6 * 6 * 2

<em><u>Rule</u></em>: Every pair of = factors allows you to take one of them outside the sqrt sign and throw the other a way. If there are no pairs, whatever you started with stays under the root sign.

sqrt(6*6*2) = 6sqrt(2)

  • The diagonal length is either
  • d = 6*sqrt(2) or
  • d = 8.4853
