Answer: C. 50 2/3
Step-by-step explanation: Multiply 9 1/2 and 5 1/3.
Answer:
$425
Step-by-step explanation:
Let the dryer cost x
and the dish washer cost y
x+y=784-----------1
y=x-66-------------2
put the value of y=x-66 in 1
x+x-66=784
2x= 784+66
2x=850
x=850/2
x=425
Hence the dryer cost $425

Step-by-step explanation:
How you find co-terminal is by adding or subtracting 360 degrees to the value you are given.
If it is a positive number like #18. all you do is subtract 510 - 360 = 150 until you get to a value between 0 degrees and 360 degrees.
The same thing applies to negative numbers. Like #21. You will add 360 + (-660) until you get to a number between 0 degrees and 360 degrees.
-660 + 360 = -300 (this is not a value in between 0 and 360 so we must add 360 again)
-300 + 360 = 60 (this is a value in between 0 and 360) (this is the co-terminal angle)
That is the idea of finding co-terminal angles.
