Answer:

x = -7

How to:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

5°x-(2°x-9)=0

Pull out like factors:

21 + 3x = 3 • (x + 7)

Equations which are never true: Solve 3 = 0

Solving a Single Variable Equation:

Solve : x+7 = 0

Subtract 7 from both sides of the equation : x = -7

If a basket of goods and services used to calculate CPI contains 2 pairs of socks at $2 each and 1 pair of shoes at $50, what wi

Svetach [21]

Answer:

B. 55.10

Step-by-step explanation:

Given:

1 pair of Shoes for 1st year = $50

2 pair of Sock for 1st year = $2 each = 2 $\times$ 2= $4

$\therefore$ CPI for year 1 = Price of shoes for 1st year + Price of Sock for 1st year= $50 + $4 = $54

Now

1 pair of Shoes for 2nd year = $51

2 pair of Sock for 2nd year = $2.05 each = 2 $\times$ 2.05 =$4.10

$\therefore$ CPI for Year 2 = Price of shoes for 2nd year + Price of Sock for 2nd year= $51 + $4.1 = $55.10

Hence CPI for Year 2 is $55.10
