Step-by-step explanation:
You just have to plug the numbers they give you into the equation. For the first one, you have 0 + 5y = 10; 5y = 10; y = 2. For the second one, x + 5(0) = 10; x + 0 = 10; x = 10. And lastly, for the third one, x + 5(6) = 10; x + 30 = 10; x = -20.
Answer:
You would use the formula: Rate = distance / time which equals 55
Since we are asked for the time it takes to reach 3/4 the destination.We just use 3/4 of the value of the distance.
55 = (3/4)(440) / t
t = 6 hours
So the answer would be "C"
Answer:
x = 2 is the solution of x^3 - x - 6
Step-by-step explanation:
(x^3) - x - 6 = 0
If x = 2,
--> (2^3) - 2 - 6
= 8 - 2 - 6 = 8 - 8 = 0.
Green Grapes:
1 pound = $1.85
3 3/5 pounds = $1.85 x 3 3/5
3 3/5 pounds = $6.66
Red Grapes:
1 pound = $2.30
3 3/5 pounds = $2.30 x 3 3/5
3 3/5 pounds = $8.28
Total = $6.66 + $8.28 = $14.94
