1/5y + 3/10y - 1/2y - 1/3y = 2/5
6/30y + 9/30y - 15/30y - 10/30y = 2/5
-10/30y = 2/5
y = 2/5 x (-30/10)
y = -6/5

Answer: y=12/20=0.6

Step-by-step explanation:

<u>Rephrase the given equation</u>

1 and 1/5y+3/10y-1/2y=1/3y+2/5

6/5y+3/10y-1/2y=1/3y+2/5

<u>Find the GCF (greatest common factor) and multiply it on both sides</u>

(6/5y+3/10y-1/2y)×30=(1/3y+2/5)×30

36y+9y-15y=10y+12

<u>Add like terms together</u>

30y=10y+12

<u>Subtract 10y on both sides</u>

30y-10y=10y+12-10y

20y=12

<u>Divide 20 on both sides</u>

20y/20=12/20

y=12/20=0.6

Hope this helps!!

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
