-6x + 100 = -10x + 160
+ 10x + 10x
4x + 100 = 160
- 100 - 100
4x = 60
4 4
x = 15
Answer:
$50.59
Step-by-step explanation:
First you take off 20% from 68. ( 68 * 0.2 = 13.6 )
68- 13.6 is 54.4
for the sales tax, you take out 7% of 54.4
54.4 * 0.07 = 3.808
54.4-3.808 = 50.59!
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
Answer:
3
Step-by-step explanation:
