Answer:
a = 1.95
Step-by-step explanation:
40a - 61 = 17
40a - 61 + 61 = 17 + 61
40a = 78
40a / 40 = 78 / 40
a = 1.95
1/3 plus 2/3 = 1 whole
So, the Rossi family ate 1 whole pizza
X/-3 = 12 + x
x = -36 - 3x
4x = 36
x= = 9
The number is 9.
You could use so many for example 4, 10, 57, 5729, any number above 4 would work since that plus 8 would be greater than 11
