Answer:
x=8 and y=3 (So, yes!)
Step-by-step explanation:
I will solve your system by substitution.
(You can also solve this system by elimination.)
−x+4y=4;−x+3y=1
Step: Solve −x+4y=4 for x:
−x+4y+−4y=4+−4y(Add -4y to both sides)
−x=−4y+4
-x/-1 = -4y+4/-1 (Divide both sides by -1)
x=4y−4
Step: Substitute 4y−4 for x in −x+3y=1:
−x+3y=1
−(4y−4)+3y=1
−y+4=1(Simplify both sides of the equation)
−y+4+−4=1+−4(Add -4 to both sides)
−y=−3
-y/-1 = -3/-1 (Divide both sides by -1)
y=3
Step: Substitute 3 for y in x=4y−4:
=4y−4
x=(4)(3)−4
x=8(Simplify both sides of the equation)

Answer:
48
Step-by-step explanation:
A square has 4 sides of equal length. 12 x 4=48
Answer: 18
Step-by-step explanation:
2 degrees per hour
9 hours
1hour = 2 degrees
2hours= 4 degrees
3hr= 6 degrees
4hr= 8 degrees
5hr=10 degrees
6hr= 12 degrees
7hr= 14 degrees
8hr= 16 degrees
9hr= 18 degrees
So you are basically doing 2x9 to get your answer
