The Russo-Japanese War was a conflict between Russia and Japan that started in the year 190419041904. Let xxx represent any year
wel
The first thing we must do for this case is to define a variable.
 We have then:
 x: number of years before the Russo-Japanese conflict began
 We write now the inequality that models the problem.
 We know that the conflict began in the year 1904, therefore, all the previous years are given by:
 x <1904
 Answer:
 
an inequality in terms of x and 1904 that is true only for values of x that represent years before the start of the Russo-Japanese War is:
 
x <1904

O is the midpoint of segment FG. FO=3x+17, OG=7x-15. <br><br><br> 98 points
AlladinOne [14]

O is the midpoint so both sides FO and OG need to equal each other.

3x + 17 = 7x - 15

Subtract 3x from both sides:

17 = 4x -15

Add 15 to both sides:

32 = 4x

Divide both sides by 4:

x = 32/4

X = 8

Now you have the value of X, solve for the lengths:

FO = 3x +17 = 3(8) +17 = 24 +17 = 41

OG = 7x -15 = 7(8) -15 = 56-15 = 41

Total length would be 41 + 41 = 82

The Baker Family spent $28 on 5 tickets.
White raven [17]

Answer:

I cannot not give the correct solution, need more context. How many children are there, how many adults are in the family? So I will explain in my explanation.

Step-by-step explanation:

If more context were given, for example:<em> 2 adults and 2 children.</em>

Then the bakers would have bought 2 adult tickets for ___ each

Then the bakers would have bought 3 children's tickets for ___ each

So using what we know we can create an equation:

<em>2A+3C=28</em>,<em> </em>

meaning 2 adult tickets plus 3 children's tickets costs a total of $28.

So we divide 28 by 5, which is the total amount of tickets.

28/5=5.6

So to figure the cost of children's tickets multiply the cost by amount.

3*$5.6=$16.8, C=16.8

To figure out the cost of the adults tickets multiple the cost by the amount.

2*$5.6=$11.2, A=11.2

a) the bakers would have bought <u>2</u> adult tickets for <u>5.6</u> each.

b) the bakers would have bought <u>3</u> children's tickets for <u>5.6</u> each.
