40 minutes is 2/3 of an hour.
30 miles per hour x 2/3 hour = 20 miles.
30 minutes = 1/2 hour.
60 miles per hour x 1/2 hour = 30 miles.
Total = 20 + 30 = 50 miles.
1/3 or 5/6
Lets make the fractions into decimals. To make a fraction into decimal you have to divide the numerator by the denominator. The numerator is the top part of a fraction and the denominator is the bottom part of the fraction.

Calculations
1/3
1 ÷ 3 = 0.3333....
5/6
5 ÷ 6 = 0.83333...
0.83333... is greater then 0.3333.....
Therefore 5/6 is greater then 1/3
1/3 is smaller then 5/6
Answer:
Denote B(x, y), we have:
-10 + x = 2 x (-16) => x = -22
8 + y = 2 x 6 => y = 4
=> B(-22, 4)
Hope this helps!

Answer:
.57%
Step-by-step explanation:
if you add $0.91 to $51.09 to get 52, then you divide $52 by $0.91 the divide it by 100.
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
