Answer:

Step-by-step explanation:
To find many more pounds of apples Kimane and his friend needs to get, we first need to find out how many pounds of apples they picked together.
Kimane = 
Friend = 
We add them together to find out how many pounds of apples they currently have.
Total Pounds = 
Just to make the equation clearer, we separate the whole numbers from the fractions.


Now since we cannot add the 2 fractions directly since they have different denominators, we need to convert the
into a fraction with the same denominator.
We multiply both the numerator and denominator by 2 to have the same denominator.

So now we have:



Now that we know how many pounds Kimane and his friend collected, we simply subtract 20 and the total amount Kimane and his friend had already collected.


So Kimane and his friend still need to get
more pounds of apples to get 20 pounds of apples.
Answer:
x=$59.69
Step-by-step explanation:
We can create a proportion to find the answer.
Thus, we get 4 hr/$39.79=6 hr/$x.
Cross multiplying gives us 4x=238.74, and solving for x gives us $59.685.
We can round to $59.69.
The question is asking for you to plug in each number in the brackets into x and solve for y, or f(x), g(x), etc. I will do no. 19 as an example:
f(x) = -3x + 1
This problem has the domains -2, -1, and 0. First, we'll start with -2:
f(x) = -3(-2) + 1
f(x) = 6 + 1
f(x) = 7
Now -1:
f(x) = -3(-1) + 1
f(x) = 3 + 1
f(x) = 4
Lastly, 0:
f(x) = -3(0) + 1
f(x) = 0 + 1
f(x) = 1
For question 23, we can use the distance formula, which is ratextime. The domain in this case is time (t). You can set up a function like this: d(t) = 60t
