There are 7 numbers. 7 X 45 equals 315. 40+45+48+54+45=232.
315-232=83.
The 2 numbers can each have different values, such as 41 and 42, or 40 and 43. The numbers must add up to 83, though.

the corner there is 90 degrees and the top corner is 30 this is because all sides of a triangle calculated always equeal 180
Step-by-step explanation:
The solution to the system of inequalities is (0.667, 5.333)
<h3>How to graph the inequalities?</h3>
The system of inequalities is given as:
y > 2x + 4
x + y ≤ 6
Next, we plot the graph of the system using a graphing tool
From the graph, both inequalities intersect at
(0.667, 5.333)
Hence, the solution to the system of inequalities is (0.667, 5.333)

What's a midpoint I never learned what a midpoint is and this is not an answer
Answer:
4
Step-by-step explanation:
The left side of the equation can be factored as the difference of squares:
(a -b)(a +b) = 105
The right side of the equation can be factored to 4 different pairs of factors:
105 = 1·105 = 3·35 = 5·21 = 7·15
For each of the factor pairs, we can match factors to get, for example, ...
a -b = 1
a +b = 105
The solution to this is a = (105 +1)/2 = 53, b = (105 -1)/2 = 52. Thus, we have ...
(a, b) = (53, 52)
For the other factor pairs, the solutions are ...
(a, b) = (19, 16), (13, 8), (11, 4)
There are a total of 4 positive integer solutions.
