Answer:
Take your numerator times the whole number, then divide by the denominator. For example,
2x15= 30
30/3= 10
2/3 of 15 would be 10
Answer:

Step-by-step explanation:
Using quadratic formula

we will have two solutions.
2x^2 - x - 4 = 0
So, a=2 b=-1 c=-4, we have:

Finally, we have two solutions:

A polynomial with roots a and b is (x - a)(x - b).
(x - 2)(x - (-1))(x - 4) = 0
(x - 2)(x + 1)(x - 4) = 0
has roots 2, -1, and 4.
Answer:
3*5
Step-by-step explanation:
We can easily see that both 3 and 5 are prime numbers so the prime factorization is 3*5
1 year=$50
1 movie=$2
25 movies×$2=$50
1 year=$50
$50+$50=$100
