Answer:
4:12
Step-by-step explanation:
I think you asked for a ratio?
You solve this by plugging one equation into the other. Usually you have to rewrite one equation to make this work. In this case I choose to rewrite y-4x=0 as y=4x.
After plugging it into the second, you get:
3x + 6*4x = 9 => 27x = 9 => x=1/3
Putting this solution back into y=4x gives us y=4/3
Answer:
25cm^2
Step-by-step explanation:
A square has 4 equal sides so each side will be 20/4 = 5cm
Easily calculate the area by taking 5 x 5 = 25cm^2
The 3 consecutive numbers are 41, 42, and 43 : 41+42+43= 126
Plug x and y when you type in the calculator
2-2(2+3) and see your answer
