Answer:
2.025
Step-by-step explanation:
In this problem, you don't necessarily need to find the exact values of a and b. Rather, find the value of (a+b) first, and then you can substitute it into the next equation. First, you can divide both sides of the first equation 2(a+b)= -8.1 by 2, to get (a+b)=-4.05. Now, subsitute the value of (a+b) into the second equation, -0.5(a+b), to get -0.5(-4.05). From here, you can calculate that -0.5 times -4.05 is 2.025. Hope this helped!
Answer:
10 weeks
Step-by-step explanation:
205+2t=195+3t
-2t -2t
205=195+t
-195 -195
10=t
Answer:
poop
Step-by-step explanation:
Using the sine law of triangles to solve for angle C:
b / sin B = c / sin C
C = arcsin (c * sin B / b)
C = 30.7<span>°
Since interior angles of a triangle always add up to 180</span><span>°, we can use this to solve for angle A:
angle A = 180</span>° - 73° - 30.7<span>°
angle A = 76.3</span><span>°
Having solved for angle A, we can solve for side a using the sine law.
a / sin A = b / sin B
a = b * sin A / sin B
a = 15.2
Therefore, the correct answer is B.</span>
