Answer:
There are 180 degress in a triangle. so minus the angles given from 180 to find X.
X = 180 - 106 - 30
X = 44 degrees
Answer:
÷2
Step-by-step explanation:
64/32 = 2
32/16 = 2
16/8 = 2
8/4 = 2
If you divide the previous number by two you get the next number.
The answer is 93 calories per bowl of soup. → The equation is 837 ÷ 9.
Answer:
D. 
Step-by-step explanation:
The period of the functions 
is 
The period of the function 
is ALWAYS 
In your case, you have function 
and this function has the period
You need to find the function that will have the period that is half of 
so
So, correct choice is
9x - y = 15
2x + 8y = 28
Use the substitution method.
Solve for y in the first equation.
9x - y = 15
-y = 15 - 9x
y = -15 + 9x
Now plug in y into the second equation.
2x + 8(-15 + 9x) = 28
2x - 120 + 72x = 28
74x - 120 = 28
74x = 148
x = 2
Plug x back into the rewritten first equation.
y = -15 + 9(2)
y = -15 + 18
y = 3
x = 2, y = 3
