Step-by-step explanation:
law of sines
29/sin(115 degrees) = 13/sin(B)
==> B = 0.418374736 rad
or 75.3074525 dgrees
The lines whose equations are given intersect at. (4, 0)
Answer:
4a³+3a-3
Step-by-step explanation:
You can solve this by combining like terms. Add the numbers with the correct exponents together.
-a³+5a³
4a-a
Thus, the answer is
4a³+3a-3
Hey there! I'm happy to help!
Let's call our hamburgers h and our cheeseburgers c and set up a system of equations to solve.
c+h=512
c=3h
Let's plug this value of c into the first equation to solve for h.
3h+h=512
4h=512
Divide both sides by 4.
h=128
Therefore, 128 hamburgers were sold on Wednesday.
Have a wonderful day! :D
