Answer:
x= -1; y= -2
Step-by-step explanation:
A: 6x+4y= -14
B: -x-5y=11
6B is : -6x-30y=66
A+6B is : -26y=52
so y= -2
so A becomes : 6x+4.(-2)= -14
so x= -1
4x^2+48x=20
4x^2+48x+144=164
(2x+12).(2x+12)= + 59rt(164)

Answer:
B. 4 miles
Step-by-step explanation:
Jim ran a total of ...
6.5 +5 +3 +2 +3.5 +4 = 24 . . . . miles
Then his average was ...
(24 miles)/(6 days) = 4 miles/day
0.0001= 1/10,000
The fourth root of 1/10,000 equals the fourth root of 1/the fourth root of 10,000.
The fourth root of 1 is 1.
The fourth root of 10,000= 10
1/10= 0.1
