Mathematics
1 answer:
oee [108]3 years ago
7 0

Answer:

It depends of what the equation is...

Step-by-step explanation:

If your equation is 3x2 (3x times 2) then the solution would be:

3(4)(2) + 5(2)= 34

If your equation is 3x + 2 + 5y, then the solution would be:

3(4) + 2 + 5(2) =24

In a restaurant 72 out of 108 tables are booths. What is the ratio of tables that are booths to the total number of tables.
denpristay [2]

Answer:

The ratio of tables that are booths to the total number of tables = \frac{72}{108}

Step-by-step explanation:

The number of tables in a restaurant, p = 108

The number of table that are booths, q = 72

Then, the ratio of tables that are booths to the total numbers of tables = \frac{q}{p}

                                                                 = \frac{72}{108}

Involves triangle centroid
Rasek [7]
Here, you do the same as the previous one, keeping in mind that X cuts TW in a 2:1 ratio.

\bf TW-TX=XW\implies \cfrac{8a}{5}+\cfrac{1}{10}-\left(a +\cfrac{4}{5} \right)=XW
\\\\\\
\cfrac{8a}{5}+\cfrac{1}{10}-a-\cfrac{4}{5}=XW\implies \cfrac{3a}{5}-\cfrac{7}{10}=XW\\\\
-------------------------------\\\\

\bf TX:XW\qquad 2:1\qquad \cfrac{TX}{XW}=\cfrac{2}{1}\implies \cfrac{a+\frac{4}{5}}{\frac{3a}{5}-\frac{7}{10}}=\cfrac{2}{1}
\\\\\\
\cfrac{\frac{5a+4}{5}}{\frac{6a-7}{10}}=\cfrac{2}{1}\implies \cfrac{5a+4}{5}\cdot \cfrac{10}{6a-7}=\cfrac{2}{1}\implies \cfrac{10a+8}{6a-7}=\cfrac{2}{1}
\\\\\\
10a+8=12a-14\implies 22=2a\implies \cfrac{22}{2}=a\implies 11=a

The length of rectangle is 5 cm greater than its width. The perimeter is 106cm. Find the dimensions of the rectangle.
antiseptic1488 [7]

Width-24 Length-29

Two sides of the rectangle are 5 cm bigger than the other two. So you would add the two 5 cm together (10cm). If you take the 10 cm off you (106-10) you will get a square. Then all you have to do is divide 96 by 4 (24), and add back on the two 5cm from the beginning to the length (29).
