You know b=-6 and since you know this, you can plug -6 in for b.
This would become 4(-6) + 6 divided by 6.
You can then multiply 4 and -6 together,
-24 + 6 / 6
You can then add -24 and 6 together,
-18/6
You can then divide -18 by 6,
-18/6=-3
-3 is your final answer
No, 4/2 is equivalent to 2. 4/6 is still a smaller fraction.

Answer: 1.8 servings of soybean and 1.2 servings rice will be needed.
Step-by-step explanation:
Let x be the number of soybeans and y be the number of rice.
Then , According to the question , we have

Multiply 2 on both the sides of equation (2), we get

Subtract equation (2) from equation (3), we get

Put x = 1.8 in equation (2), we get

Hence, 1.8 servings of soybean and 1.2 servings rice will be needed.
We know that:
time=distance/speed
if the tortoise speed is x m/min, then since 0.5 m/hr=1/120 m/min
18/x=23+18/(x+1/120)
solving for x we get:
x=0.08 m/min
speed of hare is:
(0.08+1/120)=0.088 m/min
