Answer: 5:6
Explanation:
The 2 polygons are similar
So 25/30 = 25.5/30.6 = 5/6 or 5:6
Remember you can do anything to an equation as long as you do it to both sides
(y/4)-49=-9
isolate the variable
add 49 to both sides
y/4=40
multiply both sides by 4 to clear fraction
y=160
Answer:
-3x-y=5
y-2z=7
x-4y+z=-9
