If you add up all the angles in a triangle it will always be 180.
180 - 45x is angle TRS
Therefore 180 - 45x + 25x + 57 + x = 180
Subtract 180 from both sides
-45x + 25x + 57 + x = 0
Subtract 57 frok both sides
-45x + 25x + x = -57
Combine like terms
-19x = -57
divide both sides by -19 and you get
x = 3

The sum of the angles in a triangle is 180°. It means that when you add up the three angles, you would get 180°.

The angle on a straight line, is also 180°.

Since ∠QRT = 45x, then...

∠TRS = 180° - 45x

So now you add up the angles in the triangle:

(180° - 45x) + 25x + (57 + x) = 180°

Combine like terms:

-19x + 237° = 180°

Subtract 237° to both sides:

-19x = -57

Now, divide both sides by -19:

x = 3

Write out   5t^2                    3t                            5t^2
                 -------- .  Invert --------- and multiply ---------- by the result:
                  8x^2                 (x^2)                         8x^2

                5t^2
multiply ---------- by the result:      5t^2       5*x^2     25 t^2 x^2
                8x^2                            ------- * ---------  = ----------------
                                                    8x^2         3t         8x^2 (3t)

Reducing this, we get       25t

Find the table with unit rates greater than the unit range in the graph. Then arrange these tables in order from least to greate
Lubov Fominskaja [6]

Answer:

Except table 2, all tables have greater unit rate than the graph.

The required arrangements of tables is  

Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < table 7 < Table 6

Step-by-step explanation:

Formula for unit rate :

m=\dfrac{y_2-y_1}{x_2-x_1}

From the given graph it is clear that the line passes through the points (0,0) and (11,20). So, unit rat of graph is

m=\dfrac{20-0}{11-0}=1.8181...

Similarly, we need to calculate the unit rate for each table.

m_1=\dfrac{26-13}{14-7}=\dfrac{13}{7}=1.85714

m_2=\dfrac{18-9}{10-5}=\dfrac{9}{5}=1.8

m_3=\dfrac{34-17}{18-9}=\dfrac{17}{9}=1.88..

m_4=\dfrac{42-21}{22-11}=\dfrac{21}{11}=1.9090..

m_5=\dfrac{38-19}{20-10}=\dfrac{19}{10}=1.9

m_6=\dfrac{50-25}{26-13}=\dfrac{25}{13}=1.923

m_7=\dfrac{46-23}{24-12}=\dfrac{23}{12}=1.9166..

Except table 2, all tables have greater unit rate than the graph.

The required arrangement of tables is  

Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < Table 7 < Table 6

Please helppp meee I am struggling​
erma4kov [3.2K]

Answer:

  the number of cookies ordered

Step-by-step explanation:

When an equation is written in the form ...

  (left variable) = (some expression involving one or more right variables)

we usually describe the "left variable" as the "dependent variable" and the "one or more right variables" as the "independent variable(s)".

Here, the equation is given as ...

  C = 3s + 30

__

This tells you C is the dependent variable, and s is the independent variable. The description also says "C is the number of cookies." Since you know that the dependent variable is the number of cookies, you can answer the question ...

  the dependent quantity is the number of cookies ordered.  (matches the first choice)
