Answer:
Calculus
Step-by-step explanation:
Calculus: z = (94-70)/12 = 2
Bio: z = (74.5-77)/10 = -0.25
History: z = (45-53)/16 = -0.5
Physics: (70.5-60)/14 = 0.75
-7x -7y = 21
Y = 6
Since they are giving you the value of 6 you just plug it in the equation
-7x - 7(6) = 21
-7x - 42 = 21
+ 42. +42
-7x = 63
/-7. /-7
X = -9
180-24=5
180-56=34
Both are equal
