Answer:
Pencils cost $0.12
Step-by-step explanation:
Set up a system of equations :D
let x represent pencils
let y represent pens
2x + 3y = 0.78
3x + 2y = 0.72
Because we are only interested in pencils we will solve for x first.
Isolate y in either equation, lets do the first one.
3y = 0.78 - 2x
y = (0.78 - 2x)/3
Simplify
y = 0.26 - (2x/3)
Now plug what we got into Y in the other equation
3x + 2 (0.26 - (2x/3)) = 0.72
solve by simplifying
3x + 0.52 - (4x/3) = 0.72
3x - (4x/3) = 0.20
9x/3 - 4x/3 = 0.20
lets change 0.2 into a fraction 2/10 simplified to 1/5
5x/3 = 1/5
25x/15 = 3/15
25x=3
x= 3/25 = 0.12
A LINE is What is one dimensional and has infinite length
Answer: 12 times
Step-by-step explanation: 105 - 45 for initial fee is 60 then you divide that by 5 for 12
Answer: plus or minus 1, 1/2, 2, 5, 5/2, and 10
Explanation:
To find the possible roots
We first find the factor of the constant term:
10: 1, 2, 5, 10
Then we find the factor of leading coefficient:
2: 1, 2
And the possible rational roots are:
Plus or minus [1/1, 1/2, 2/1, 2/2, 5/1, 5/2, 10/1, 10/2]
Then we get rid of the duplicate:
Plus or minus [1, 1/2, 2, 5, 5/2, 10]
