The answer is 2.7

I’m not an expert at this but i did some research so I hope I can help

It’s 2.7 because the formula for calculating density is to divide the mass by the volume and in you do that for each of them you get 2.7 every time

Answer:

Probability of finding girls given that only English students attend the subject =33/59

Step-by-step explanation:

Given that during English lesson, there is no other lesson ongoing. The probability of getting girls in that class only will be equivalent to 33/59 since we expect a total of 59 students out of which 33 will be girls. Similarly, in a Maths class given that only Maths students attend the class, probability of having a girl is 29/61 since out of all students, only 29 prefer Maths and the total class attendance is 61

Solving for x on the question - <em>2x + 3y = 32</em> |

Answer : x = $\frac{-3}{2}$ ⁻y + 16

Solving for y on the question - <em>2x + 3y = 32</em> |

Solving for x on question - 5x - 4y = -81 |

Answer : x = $\frac{4}{5}$ y + $\frac{-81}{5}$

Solving for y on question - 5x - 4y = -81 |

Answer : y = $\frac{-5}{4}$ x + $\frac{81}{4}$

<h2>Step-by-step explanation:</h2>

<em>(Solving for x on question - 2x + 3y = 32)</em>

2x + 3y = 32

Step 1: Add -3y to both sides.

2x + 3y + −3y = 32 + −3y

2x = −3y + 32

Step 2: Divide both sides by 2.

$\frac{2x}{2}$ = $\frac{-3y+32}{2}$

<u>x = </u> $\frac{-3}{2}$ <u>⁻y + 16</u><u> </u>

<em>(Solving for y on question - 2x + 3y = 32)</em>

2x + 3y = 32

Step 1: Add -2x to both sides.

2x + 3y + −2x = 32+ −2x

3y = −2x + 32

Step 2: Divide both sides by 3.

$\frac{3y}{3}$ = $\frac{-2x+32}{3}$

<u>y = </u> $\frac{-2}{3}$ <u>x + </u> $\frac{32}{3}$ <u> </u>

<em>(Solving for x on question - 5x - 4y = -81)</em>

5x − 4y = −81

Step 1: Add 4y to both sides.

5x − 4y + 4y = −81 + 4y

5x = 4y − 81

Step 2: Divide both sides by 5.

$\frac{5x}{5}$ = $\frac{4y-81}{5}$

<u>x = </u> $\frac{4}{5}$ <u>y + </u> $\frac{-81}{5}$ <u> </u>

<em>(Solving for y on question - 5x - 4y = -81 )</em>

5x − 4y = −81

Step 1: Add -5x to both sides.

5x − 4y + −5x = −81 + −5x

−4y = −5x − 81

Step 2: Divide both sides by -4.

$\frac{-4y}{-4}$ = $\frac{-5x-81}{-4}$

y = $\frac{-5}{4}$ x + $\frac{81}{4}$
