Answer:
Step-by-step explanation:
1) y = 50x + 2500
2) y = 200x + 1000
if we build a system with the two equations, we have:
50x+2500 = 200x + 1000
150x = 1500
x = 10
y = 2000 + 1000 = 3000
3) 10
4) $3000
(x+3)(2x-6)=26
2x(to the second power)-18=26
2x(to the second power) -18-26=26-26
2x(to the second power)-44 = 0
x=square root of 22,x= negative square root of 22
decimal form : x = 4.69042,x= -4.69042

Answer:
87,600 minutes
Step-by-step explanation:
Given that practice time by Jonas :
1 hour per day for 2 years :
Bradley practices : 2 hours a day more than Jonas,
How many more minutes does Bradley practice the guitar than Jonas over the course of 2 years
Number of days in a year = 365 days
2 hours per day for (2 * 365) days :
2 * (2 * 365) = 1460 hours
Recall :
60 minutes = 1 hour
(60 * 1460) = 87,600 minutes
Answer:
3s - 10 = 65
Step-by-step explanation:
s = the shirt price
Since Jason bought 3 shirts, we need to multiply the 3 shirts by its value which would be 3s. He has a coupon for $10 off, so we need to subtract 3s by 10. Since he spent $65 we need to set the whole equation equal to 65 and out final answer would be 3s - 10 = 65.
