The answer to -3-8+(-4) is -15
Answer: The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.
Write and solve an equation, as follows:
-7y + 5(3+ny) = 3y + 15. We are to find the value of 'n.'
-7y + 15 + 5ny = 3y + 15.
Subtracting 15 from both sides, we get -7y + 5ny = 3y
Grouping like terms, we get 5ny = 3y + 7y = 10y
Dividing both sides by 5y, we get n = 2 (answer)
The club can buy 5 computers with $3472
Step-by-step explanation:
The number of computers which can be bought from the given amount will be calculated by dividing the amount by price of one computer.
Given
Total amount = $3472
