Answer:
gallons
Step-by-step explanation:
Considering she waters her plants with 25 1/2 gallons i.e 51/2
and with the new system, she does it with 19 3/4 i.e 79/4
taking the difference:
= 
gallons per day
For 30 days:
30 x = 172.5 or gallons
1) we calculte the driver´s unit rate of speed.
s=speed
d=distance
t=time.
s=d/t
45 miles------------------3/4 hour
x----------------------------- 1 hour
x=(45 miles * 1 hour) / (3/4 hour)=60 miles.
speed or rate=60 miles / 1 hour.
2)we calculate the distance traveled at 1.25 hour.
distance=rate * time
distance=(60 miles /1 hour) * 1.25 hour=75 miles.
Answer: the driver would´t go late, because, the distance is 65 miles, and he can travel 75 miles if he drive with that speed .
Don’t mind this comment just need points but good luck
Answer: y = 2x - 4
Step-by-step explanation:
Gradient => (2 - (-2))/(3 - 1) = 4/2 = 2
so, equation is y = 2x + C
Using (3, 2) we have: 2 = 2(3) + C
Hence, C = -4
Therefore, y = 2x - 4
