Answer:
Step-by-step explanation:
Weight decreased = 108 - 88 = 20 Kg
Percentage decrease = 
= 18.52%
Answer:
x = 7, y = 30 and x = 3, y = 10
Step-by-step explanation:
5x - y = 5, then y = 5x - 5
2y - x^2 = 11
2(5x - 5) - x^2 = 11
10x - 10 - x^2 = 11
-x^2 + 10x -10 = 11
-x^2 + 10x -21 = 0
x^2 - 10x + 21 = 0
(x - 7)(x - 3) = 0
x = 7, y = 30
x = 3, y = 10
Let's solve your equation step by step
(3^2)(x)-5=81
step 1:simplify both sides of the equation
(3^2)(x)-5=81
simplify.
9x-5=81
step 2:Add 5 to both sides.
9x-5+5=81+5
9x=86
divide both sides by 9.
9x/9=86/9
x=86/9
Answer:86/9
