Let xxx represent any year. Write an inequality in terms of xxx and 190419041904 that is true only for values of xxx that represent years before the start of the Russo-Japanese War.

Step-by-step explanation:

The Russo-Japanese war was fought from 8 February 1904 – 5 September 1905. Any year x before the start of the war will be less than 1904,(e.g. 1903, 1902 and so on). Therefore the inequality that is true for any year x is:

70

step-by-step explanation:

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
