2.1 is already in a decimal form.
Hope I helped!
Answer:
x= 4
y= -5
Step-by-step explanation:
-2x+6y=-38 equation 1
3x-4y=32 equation 2
using equation 1 we have:
-2x+6y=-38
6y +38 = 2x
3y + 19 = x equation 3
using equation 3 in equation 2 we have:
3(3y + 19) - 4y = 32
9y + 57 -4y =32
5y = 32 -57
5y = -25
y= -25/5
y = -5
so we have:
3y + 19 = x
3(-5) +19 = x
x= 4
What do you mean about that?
75% I think.
because if you do 560 - 420 you get 140.
140 / 560 x 100 = 25
which means there is a 25% decrease, so they took 75%.
