You would set it up: .5/100 = x/490 and then cross multiply .5 time 490 and 100 times x, and end up with: 245=100x. divide by 100, and get 2.45
Answer:
43
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
We assume that the given expessions represent the measures of the alternate interior angles, so are equal.
... (4x + 12)° = 7x°
... 12 = 3x . . . . . . . divide by degrees, subtract 4x
... 4 = x . . . . . . . . . divide by 3
_____
Then the angles are 7x° = 28° = (4x+12)°.
C and D because
Domain is the values of x and range are the values of y
X can have the value of any real numbers and
Y can only have the value 3
