Answer: B is correct, 40 degrees.
Step-by-step explanation:
70 is the given angle, z is equivalent to that angle, so z is 70. So add those together, and you have 140. According to the rule, a triangle will always add up to 180. So 180-140=40 and there's your answer. Hope this helps!
Answer:
8y = -6
Step-by-step explanation:
Simply add the equations as you would numbers.
The 'x's cancel each other out. The 'y's add together as normal numbers.
9 + (-15) = -6

Answer:
Answer choice a.
Step-by-step explanation:
Let's do part of the work of solving the given system:
6x + 2y = −6
3x − 4y = −18
Multiply the first equation by 2 so as to make the coefficient of y = to 4:
12x + 4y = -12
Combine this result with the second equation:
12x + 4y = -12
3x − 4y = −18
------------------------
15x = -30
Note that these results are precisely the same as the equations in Answer Choice a.
