Answer:
<h3>Step 4</h3>
Step-by-step explanation:
Given the expression 7+(-2)
Let 7 be 7 positive tiles since it is a positive number
Let -2 be 2 negative tiles being a negative number
7+(-2) = 7 positive tiles <em>and</em> 2 negative tiles
note that + * - will give minus sigh (-), the expression will become:
7+(-2) = 7-2
7-2 = 5
Hence the expression gives 5 positive tiles not 2 positive tiles according to Jillian calculations in step 4.
Hence Jillian made an error in step 4
Estimate the total amount you should plan to spend on gasoline for the entire trip
<em>Total distance of the trip</em> = 1430 miles
<em>After 350 miles, refill tank</em> = $35
This means 350 miles cost $35
1430 miles cost $x
solve using ratio
350 : 35 = 1430 : x
350/35 = 1430 / x
10 = 1430/x
<em>cross product</em>
10x = 1430
<em>Divide both sides by 10</em>
x = 1430 / 10
x = $143
Therefore, the total amount you should plan to spend on gasoline for the entire trip is $143

Answer:
There are a total of 
functions.
Step-by-step explanation:
In order to define an injective monotone function from [3] to [6] we need to select 3 different values fromm {1,2,3,4,5,6} and assign the smallest one of them to 1, asign the intermediate value to 2 and the largest value to 3. That way the function is monotone and it satisfies what the problem asks.
The total way of selecting injective monotone functions is, therefore, the total amount of ways to pick 3 elements from a set of 6. That number is the combinatorial number of 6 with 3, in other words
Answer:

Step-by-step explanation:
garden: Area = 7 x 4 = 28
plants: Area = 1 x 1 x 30 plants = 30
30 - 28 = 2
Answer: 2 plants
