Step-by-step explanation:
√(20) is approximately 4.5 so it is between 4 and 5
Answer:
No Solutions.
Step-by-step explanation:
I will solve your system by substitution.
3y−3=3x; −3x+3y=−57
Step: Solve 3y−3=3x for y:
3y−3+3=3x+3 (Add 3 to both sides)
3y=3x+3
(3y/3=3x+3)/3
(Divide both sides by 3)
y=x+1
Step: Substitute x+1 for y in −3x+3y=−57:
−3x+3y=−57
−3x+3(x+1)=−57
3=−57 (Simplify both sides of the equation)
3+(−3)=−57+(−3) (Add -3 to both sides)
0=−60
The sales tax is 1.56
The way you get this is 2 divide by 25 then, multiply that number by 19.49
No.

is just division. You divide the top by the bottom.
3 / 5 = 0.6
So, 0.6 does not equal to 3.5.
