Step-by-step explanation:
it's easy to prove in any right triangle with a 30° angle, the side opposite to that angle is half the hypotenuse. CA (1/2)BC, CA/BC=1/2
Replace y in the second equation with the value of Y from the first equation:
-x - 3 = 5
Add 3 to both sides:
-x = 8
Multiply both sides by -1:
x = -8
The answer is:
(-8,3)
You set it equal to 0 then solve. you would move 4 over to the other side so you would have 1/5w=-4 then multiply -4 by the opposite of 1/5 which is 5. and you get
w= -20
You would start by 6÷3. This would tell you that for every proud of hamburger you pay $2.
Therefore multiply 10×2 and that equals 20.
Therefore, your answer is $20.
