Well i did 120/15 and got 8 so he runs a mile every 8 minutes about. so you do 8 x 6 because he has to run 6 miles and bam 48 it takes him 48 minutes to run 6 miles. he runs about (.125) miles an hour ( i was assuming you meant 15 miles in 120 minutes)
Answer:
25%
Step-by-step explanation:
.25(3,600)=900
3,600+900=4,500
Answer:
Step-by-step explanation:
For the equation:
-1=5 x^2 - 2 x
5 x^2 - 2 x + 1 = 0, then we substitute: a=5, b=-2, c =1
to discriminant formula: D= b^2 - 4 a c = (-2)^2 - 4 * 5 * 1 = 4 - 20 = - 16
Answer:
The discriminant is equal to -16 which means the equation has no real number solutions.
