Answer:
47 tickets
Step-by-step explanation:
1000=300+15t
subtract 300
700=15t
divide by 15
46 2/3=t
round up
47
Answer:
3x + 15 = 3*10 + 15 = 30 + 15 = 45
<u>3x + 15 = 45</u>
Now,
2x + 25 = 2*10 + 25 = 20 + 25 = 45
<u>2x + 25 = 45</u>
Step-by-step explanation:
3x + 15 + 2x + 25 = 90
or, 5x + 40 = 90
or, 5x = 90 - 40
so, 5x = 50
so, x = 50/5 = 10
Perimeter of a rectangle = 6x + 8
Solution:
Given area of a rectangle =
Let us first factor the given polynomial.
Taking out common terms in the above expression
Taking out common term in the above expression
Area of a rectangle = l × b
Therefore, and
Perimeter of a rectangle = 2(l + b)
The answer is same if you take <em>l</em> = x + 3 and <em>b</em> = 2x + 1.
Hence, perimeter of a rectangle = 6x + 8.
