F(n) of the sequence is: 2.5
2 x 2.5= 5
5 x 2.5= 12.5
Etc.
Draw two lines that never intersects and those are parallel line. A compass and straightedge helps you make the lines straight.
Answer:
110.386
Step-by-step explanation:
what you have to do is take 20% of 142.25 (which you can do by looking it up or multiplying 142.25 by 20 and then multiplying that by .1) then you find 3% of that and add the 3% (by using the steps i gave you for the 20%)
We define the variables of the problem:
x = expensive tea
y = less expensive tea
We write the system of equations:
7x + 4y = 6.10 * (140) = 854
x + y = 140
The system of equations is:
7x + 4y = 854
x + y = 140
Resolving we have:
x = 98
y = 42
Note: see attached image for the solution.
Answer:
