Answer:
d. 3/2r+2c ≤ 10
Step-by-step explanation:
The amount of flour Molly needs for r batches of oatmeal raisin cookies is ...
3/2r
The amount of flour Molly needs for c batches of chocolate chip cookies is ...
2c
The total amount of flour Molly can use for cookies cannot exceed the amount available, so ...
3/2r + 2c ≤ 10

<em>Comment on the question</em>
The wording is a bit odd. It asks for the amount of flour available—after it tells you the amount available is 10 cups. (I might write that as <em>f ≤ 10</em>.) The answer choices clearly suggest that what is wanted is a representation of the possible mix of batches of cookies for which Molly could use the available flour. IMO, this is another instance of poor editing of math problem wording.
1000 gram = 1 kilogram
If 200 gram = $8.12. 1, it means we can get 5 bags of such amount (1000/200 = 5)
Therefore, 1kg = $8.12 * 5 = $40.6
No, the system is inconsistent.
Step-by-step explanation:
If the last column is a pivot column, then that row gives an equation that looks something like 0x+0y+0z=1 , meaning , 0=1. Clearly, this is false.
So, the system of linear equations is inconsistent.

How To Find Volume of Pyramid With Slant Height? If 'x' is the base length, 's' is the slant height, and 'h' is the height of a regular pyramid, then they satisfy the equation (the Pythagoras theorem) (x/2)2 + h2 = s2.
Option A: 
is the solution
Explanation:
The solution of the given inequality is the set of all the possible values of x.
The graph shows the number line in which the shaded region is from the right of -4 and the arrow of solution goes to infinity.
Also, There is a closed circle at the point -4.
This means that -4 is included in the solution set.
The solution to the inequality is the set of all the real values which are greater than or equal to -4.
Thus, the solution is x ≥ -4
Hence, the solution is
