2.9 because 1.16 plus 1.16 is 2.32. If each is a pound split it in half and add 2.32 it and y'all get 2.9
Answer:
x = -9, y = -3.
As an ordered pair it is (-9, -3).
Step-by-step explanation:
Substitute x = 3y in equation 1:
2y + 3y = -15
5y = -15
y = -15/5
y = -3.
Now find x by plugging y = -3 in x = 3y:
x = 3*-3 = -9.
Check the answer in equation 1:
2(-3) + -9
= -6 - 9
= -15 Correct.
Answer:
Step-by-step explanation:
We know that . Rounding the value of b as asked in the problem gives b=12.
From the right-triangle definition of cosine, b must be the adjacent side to the angle 22.6º and the hypothenuse of the triangle must be 3.
Then, a is the opposite side of the angle 22.6º therefore using the definition of sine, . Solving for a, we obtain .
We conclude that .
This is false. the answer should be x+5
Step-by-step explanation:
Angle at Center = 2 * Angle at Circumference
Therefore B = 2A.
When B = 100°, A = 100°/2 = 50° (B),
When A = 48°, B = 2(48°) = 96°. (C)
