Answer:
110
Step-by-step explanation:
Let x = rate #1 and then 155-x=rate #2.
15x + 5(155-x) = 1225
15x - 5x + 775 - 1225
10x = 450
x = 45, second rate is 110
The answer is -3. I just did it on a calculator
Answer:
60miles
Step-by-step explanation:
if they drove x miles in the city and y miles on the highway then you know that
x + y = 280
x/12 + y/20 = 16
x + 12y/20 = 16*12 = 192
8y/20 = 88
y = 220
x = 280-y = 280-220 = 60
