Answer:
(2x -3)
Step-by-step explanation:
If you assume that the result is a binomial, you can find the terms of it from ...
(8x^2)/(4x) + (3)/(-1) = (2x -3)
As a check, you can multiply it out.
(2x -3)(4x -1)/(4x -1) = (8x^2 -14x +3)/(4x -1) . . . . as required
The quotient is (2x -3).
Answer:
If you take 5 percent of a number and get 60, then what is that number?
In other words, you know that 5 percent of a number is 60 and you want to know what that initial number is.
To solve this problem you multiply 60 by 100 and then divide the total by 5 as follows:
(60 x 100) / 5
When we put that into our calculator, we get the following answer:
1,200

I may be wrong bc I suck at algebra. literally who is gonna use algebra ever?
Step-by-step explanation:
You can use the unituary method in this one
First card:
$25/750 min
divide both sides by 750 to figure out how many $ per min the calling card would be
25/750=0.033333333333333333333333333333333333333
750/750=1
the first card costs $0.03333333(going on)/min
Second card
$40/1,300 min
Divide both sides by 1,300
40/1300=0.03076923
1300/1300=1
Second card costs $0.03076923/min
$0.03076923<$0.03333333(going on)
therefore the second card is the better deal
