What is the cost of 2 kilograms of flour if 3 kilograms cost $4.86 and the unit price for each packages of flour is the same

Pavlova-9 [17]

The answer is: $3.24.

$\frac{4.86}{3} = \frac{x}{2}$
$\frac{9 .72}{3} = \frac{3x}{3}$
$3.24 = x$

(3m2 + 8 - 3) + (n + 3) <br> Simplified

RUDIKE [14]

Answer:

$\boxed {3m^{2} + n + 8}$

Step-by-step explanation:

Simplify the following expression:

$(3m^{2} + 8 - 3) + (n + 3)$

-Subtract $3$ from $8$ :

$(3m^{2} + 8 - 3) + (n + 3)$

$3m^{2} + 5 + n + 3$

-Add $5$ and $3$ :

$3m^{2} + 5 + n + 3$

$\boxed {3m^{2} + n + 8}$

Therefore, the final answer is $3m^{2} + n + 8$ .

What is the value of x?

Andrew [12]

<h3>Answer:</h3>

$x = 25$

<h3>Solution:</h3>

$\frac{40}{40+24} = \frac{x}{x +15} \\ \frac{40}{64} = \frac{x}{x +15} \\ \frac{5}{8} = \frac{x}{x +15} \\ 5(x +15) = 8x \\ 5x +75 = 8x \\ 75 = 3x \\ 25 = x$

<h3>Explanation:</h3>

Angle BDR is congruent to angle QDC because they share common angles. Angles BRD and QCD are congruent because lines BR and QC are <em>parallel</em> and line DR intersecting them creates <em>two corresponding angles</em>, BRD and QCD. Because of the reasons I mentioned, Triangles DBR and DQC are similar by Angle Angle Similarity Postulate and because these two triangles are similar they must share the same scaling factor of corresponding sides (example: $\frac{DQ}{DB}\\$ ). So $\frac{DQ}{DB} = \frac{DC}{DR}\\$ .
