48 = 2s - 3 shows an equality between number of political articles that Reggie wrote this year
<h3><u>Solution:</u></h3>
Given that, Reggie wrote a total of 48 political articles for the town newspaper this year
Number of political articles = 48
Let s represent the number of sports articles he wrote
The number of political articles he wrote is 3 less than twice the number of sports articles he wrote
Number of political articles = twice the number of sports articles - 3
Number of political articles = (2 x number of sports articles) - 3
Number of political articles = 2s - 3
We know that, number of political articles = 48
48 = 2s - 3
Thus above equation shows an equality between number of political articles that Reggie wrote this year
Answer:
52 tickets cost $10 and 18 tickets cost $12
Step-by-step explanation:
10x+12y=804. (1)
x+y=70. (2)
From (2)
x=70-y
Substitute x=70-y into (1)
10x+12y=804
10(70-y)+12y=804
700-10y+12y=804
700+2y=804
2y=804-700
2y=104
y=104/2
y=52
Recall
x+y=70
x+52=70
x=70-52
x=18
