Step-by-step explanation:
x + y = 985
2.95x + 9.95y = 7343.75
-2.95x - 2.95y = -2905.75
7y = 4438
y= 634 steak sandwiches
x + 634 = 985
x = 351 hot dogs
Line segment AD is 4cm. Because A is the center, any lines coming off the centerpoint are congruent. So if line AC is 4cm, then line AD has to be 4cm as well.
The answer is 5/12 because 1/6 converts to 2/6 and 7/12-2/6 is equal to 5/12
I think 3x, 5x, and 7. In expressions terms are what's being added or subtracted.
