Answer:
I'm sure it is 180 degrees
Answer:
One solution, x = 8/9
Step-by-step explanation:
One way to solve this is to take one equation and substitute into the other and then solve. So, take y=5(x-4) and put that into the other equation.
4x + 12 = -y
4x + 12 = -(5(x-4)) <--- substitution here
4x + 12 = -5(x-4)
4x + 12 = -5x + 20 <-- simplifying
4x + 5x = 20 - 12
9x = 8
x = 8/9
Answer:
» 4:18 and 2:12 are not equivalent.
» 5:20 and 15:60 are equivalent.
» 17:3 and 68:12 are equivalent.
☑ 68:12 is equivalent to 17:3 by a quarter.
☑ 15:60 is equivalent to 5:20 by a third.
Step-by-step explanation:
» Ratios are equivalent only in terms of multiplication and division.
» Considering the greatest ratio;

» Divide it by 4
