$x = 4.82$

Step-by-step explanation:

Given equation is:

6.2 ÷ (2x+1) = 2 1/3 ÷4

Applying the division operation

$\frac{6.2}{2x+1} = 2\frac{1}{3} * \frac{1}{4}\\\frac{6.2}{2x+1} = \frac{7}{3}*\frac{1}{4}\\\frac{6.2}{2x+1} =\frac{7}{12}\\$

Cross multiplication

$6.2(12) = 7(2x+1)\\14x+7 = 74.4\\14x = 74.4-7\\14x = 67.4$

Dividing both sides by 14

$\frac{14x}{14} = \frac{67.4}{14}\\x = 4.8142857....$

Rounding off to nearest hundredth

$x = 4.82$

Work out the area of a rectangle with base, b = 32mm and perimeter, P = 82mm.

Amanda [17]

Perimeter = 2base + 2base
82 - 2(32) = 18 : 2 = 9
area = 9*32 = 288mm^2

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

Answer:

see below

Step-by-step explanation:

The y-coordinates of the points are the same, so the distance between those points will be the difference of the x-coordinates. The first number line shows those x-coordinates plotted properly. It can be used to find the difference between them.
