Answer:
x = 1
y = -2
Step-by-step explanation:
x = 19 + 9y
3x- 3y = 9
________
3(19+9y)-3y=9
y=-2
x=19+9(-2)
x=1
(1,-2)
Assuming he's going 12 miles per hour, and 10 miles per hour.
Firstly he rode his bike for 2 1/3 hours at 12 miles per hour,
12 miles = 1 hour
24 miles = 2 hours
4 miles = 1/3 hour
He rode 28 miles in the first 2 1/3 hours.
Secondly, he rode his bike at the speed of 10 miles per hour for 1 1/2 hours
10 miles = 1 hour
5 miles = 1/2 hour
He rode his bike for 15 miles for the next 1 1/2 hours, together he rode his bike for 43 miles (28 + 15).
2a and 15a. These are like terms due to the fact they have the same variables in this case "a".
