Answer:
25% Decrease
Step-by-step explanation:
15/20 is 75%. 100-75 (since they read less) is 25%
Y + 0.4 = 2 .....subtract 0.4 from both sides
y = 2 - 0.4
y = 1.6 <==
Plug in your Y value into the bottom equation like so:
4x + 3x-3=11, combine like terms
7x-3=11 solve for x
7x= 14
x=2
Plug in x value into first equation
y = 3(2) -3
y= 6-3, y = 3
answer: (2,3)
