Answer:
C
Step-by-step explanation:
y = -1/4 x + 4 //Change
x = -1/4 y + 4 //Sub 4
x - 4 = -1/4 y //Change sign
-x + 4 = 1/4 y //Multiple 4 on both side
-4x + 16= y
y = -4x + 16
Answer:
The answer is No Solution
Step-by-step explanation:
move 5x over to the left side and you get -5 = -1 which is false because -5 can't equal -1.
For each 26 miles she needs 1 Gallon
For a distance of 2d , she will need x
Since the distance is proportional to the number of miles I can right:
2d/26 = 1/x or x =2d/26 or x=d/13
20% off
100-20=80
find 80% of 179
percent mean psarts ouf o 100
80%=80/100=0.8
'of' means mutipy
80% of 179=
0.8*179=143.2
