Answer:
(5x-3)(2x-5)
Step-by-step explanation:
10x^2 - 31x + 15
=(10x^2-6x)+(-25x+15)
=2x(5x-3)-5(5x-3)
=(5x-3)(2x-5)
I hope this helps!
If you flip a coin 100 times and see how many times you get heads. then divide that by four that will be the probability.
7/10 ÷ 1/5 = 3 1/2 because if you just find the reciprocal of the second number (in this case 1/5) and then simply multiply the two numbers straight across after you find the reciprocal, you will need to convert and simplify as needed, and then you get your answer.
This is the steps how i solved it.
the answer is 39.8
