Answer:
90 minutes or 1.30 hours
Step-by-step explanation:
In 72 minutes, Sue ran 12 miles per hour
In 1 minute, Sue ran 12/72 miles per hour
In 60 minutes, Sue ran (12/72)*60 miles per hour
= 10 miles per hour
Remaining miles after completing 12 miles in 72 minutes = (24-12) = 12 miles.
If the mileage decreases to 2 miles per hour, he will now run = (10 - 2) = 8 miles per hour.
Now,
1 hour = 60 minutes
Sue can run 8 miles in 60 minutes
Sue can run 1 miles in 60/8 minutes
Sue can run 12 miles in (60/8)*12 minutes
= 90 minutes or 1.30 hours
Suppose the corn size is 10 inches now. SO, according to the problem it grows 3 inches per week. Hence corn will be
10+3=13 in the next week.
13+3=6 in the second week
16+3=19 in the third week and so on.
So, the changes in the plant size is always equal.
Hence, it's an example of linear function.
Answer:
1578/1
Step-by-step explanation:
Because, it would still simplify to 1578.
Step-by-step explanation:
(7x - 5x) -3 =x+4
2x - 3 = 2x + 7
Y = -4x - 2
P (-16, -11)
a = -4, b = 0, c = -2
m = -a/b
m = -(-4)/(-2)
m = 4/(-2)
m = -2
y-yo = m(x-xo)
y-(-11) = -2[x-(-16)]
y+11 = -2(x+16)
y+11 = -2x-32
2x+y+11+32 = 0
2x+y+43 = 0
