(x - 3) + (x - 6) + x = 63
x - 3 + x - 6 + x = 63
Combine like terms
3x - 9 = 63
Isolate the constant
3x - 9 + 9 = 63 + 9
3x = 72
Isolate the viable
3x / 3 = 72 / 3
x = 24

a_sh-v [17]

Answer:

10

Step-by-step explanation

The earthquake  measures 6.4 on the Richter scale which struck Japan in Jullu 2007 and caused and extensive damage. Earlier that year, a minor earthquake measuring 3.1 in the Richter scale has stroked in parts of Pennsylvania.

Fomular:

The magnitude of an earthquake is M log(I/S)

where I donates the intensity of the earthquake and S be the intensity of the standard earthquake.

Calculation:

Consider that M1 be the magnitude Japanese earthquake and M2 be the magnitude of the Pennsylvania earthquake and L1 be the intensity of the Japanese earthquake and L2 the intensity of the Pennsylvania  earthquake.

Here the magnitude of the Japanese earthquake is M1 = 6.14 and the magnitude of the Pennsylvania is M2 = 3.1

By the use of magnitude of the earthquake fomular M = log I1/S, the intensity of the Japanese earthquake is calculated as follows .

M1 = log I1/S

I1/s = 10

g100num [7]

Answer:

Bag 2

Step-by-step explanation:

Given

Bag 1:

14\ ounce = 3.50

Bag 2:

24\ ounce = 5.28

Required

Which is a better buy

To get which buy is better, we first get the unit price of each bag.

Unit\ Price = Amount/Size

For bag 1:

Unit\ Price = 3.50/14

Unit\ Price = 0.25

For bag 2:

Unit\ Price = 5.28/24

Unit\ Price = 0.22

The best buy is the one with smaller unit price

Hence, bag 2 is better to buy
