Answer:
B. 21x + 40 ≤ 124
Step-by-step Explanation:
Maximum amount budgeted = $124 (this means they can't spend more than this)
x = number of people
Cost per head = $21
Given that Mr Walter already spent $40, which is part of the money budgeted, the number of people that can go canoeing cam be expressed with the following inequality:
21x + 40 ≤ 124
(note: the amount total to be spent will either be equal to or greater than $124, because it's the maximum amount budgeted for spending).

b) 39
C) 182
Answer:
Step-by-step explanation:
The question we have at hand is, in other words,
- where we have to solve for the value of
If we have to isolate here, then we would have to take the inverse of the following matrix ...
... so that it should be as follows ...
Therefore, we can conclude that the equation as to solve for " " will be the following,
- First find the 2 x 2 matrix inverse of the first portion,
= = =
At this point we have to multiply the rows of the first matrix by the rows of the second matrix,
,
- Simplifying this, we should get ...
... which is our solution.
The second answer from the top is correct. Your original choice is incorrect because the 7x and the 3 are not both being squared as the statement suggests.
