What you must do is add up the total amount of medical expenses:
Albert's medical expenses total $ 12,000
Sam's come to $ 8,000
Adding we have:
$ 12,000 + $ 8,000 = $ 20,000
Sue Jones is insured for the amount of 10/20
So:
(10/20) * (20000) = 10000
answer
The insurance will pay $ 10,000
Answer:
Philip, after 12 seconds, is 13.44 meters farther ahead after 12 seconds
Step-by-step explanation:
Philip
6.59 x 12 = 79.08
Mary
5.47 x 12 = 65.64
79.08 - 65.64 = 13.44
Hello !
Okay so what you do is add 10 to the other side
2k - 10 +10 = 6 + 10
You would get ....
2k = 16
Next you divide 16 by 2 which is 8
and that means 8 is equal to k
K = 8
Answer:
B. y = 2.5
Step-by-step explanation:
Diane's average speed= 25/y km/h.
Ed's speed= (25/y) - 6 km/h.
Ed walks 25-3 = 22 km.
Consider Ed's journey:
Speed = distance / time so:
(25/y) - 6 = 22 / (y + 3) ( 3 hours longer = y + 3)
(25 /y - 6)(y + 3) = 22
25 + 75/y - 6y - 18 = 22
6y - 75/y = 25 - 18 - 22
6y - 75/y + 15 = 0
6y^2 + 15y - 75 = 0
2y^2 + 5y - 25 = 0
(2y - 5 )(y + 5) = 0
y = 2.5, -5.
y = 2.5 ( as it must be positive.
