the ans is C..... good luck
12^2 - 6^2 * 3^4 + 5^3
(144) - (36) * (81) + (125)
144 - (36 * 81) + 125
144 - 2916 + 125
-2,772 + 125
-2,647

Answer:
x=8
Step-by-step explanation:
2x+13 = -3x +53
Add 3x to each side
2x+13+3x = -3x+53+3x
5x+13 = 53
Subtract 13 from each side
5x+13-13 = 53-13
5x = 40
Divide by 5
5x/5 = 40/5
x=8
so he's losing 4/10 of a Kg daily, how many times will that equal 3.2 Kgs? namely how many times does 4/10 go into 3.2?
well, let's firstly convert 3.2 to a fraction, and then divide.
