Answer:
3 hours
Step-by-step explanation:
let x = # of hours
Amy: y = 25 + 15x
Dan: y = 10 + 20x
Set the expressions equal to each other and solve for x
10 + 20x = 25 + 15x
20x = 15 + 15x
5x = 15
x = 3
Answer:
Option D. a^2+6ab-2ba
Step-by-step explanation:
Option D because we have like terms: 6ab and -2ba=-2ab, then
a^2+6ab-2ba=a^2+6ab-2ab
Simplifying on the right side of the equation adding like terms:
a^2+6ab-2ba=a^2+4ab
Tangent theta = opp/adj = 48/36 = 4/3
