Answer:
6738752.62
Step-by-step explanation:
1,455.8 x 4,628.9=6738752.62
If you understand what is linear pair, you can see the same in triangle also. A linear pair is a pair of adjacent, supplementary angles. Adjacentmeans next to each other, and supplementary means that the measures of the two angles add up to equal 180 degrees.
I would solve the first equation for x and then sub that value into x in the second equation. That's the easiest way. x - 2y = 3 solved for x is x = 2y+3. Now sub that in for x in the second equation: 5(2y+3)+3y=2 and 10y + 15 + 3y = 2. 13y = -13, and y = -1. Now sub that y value into either equation to solve for x: x = 2(-1) + 3 gives us an x value of x = 1. Therefore, your solution to this system is (1, -1), first choice above.
Answer: C
Step-by-step explanation: C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
Total: 1000
20 had fever, so 1000 - 20 = 980 who did not have fever
Total who did not have fever: 980
As 880 not fever and not inflamation, 980 - 880 = 100
So, 100 had inflamation but not fever.
We need the 2 statements and they alone do not answer the question
