Step-by-step explanation:
Alright. I can't really explain much but i can get your answer.
AS A DECIMAL: 1.047197551196597746154214461093167628065723133125035273658
As a property:
π/3
Sorry if its wrong... I tried lol
Multiply 4.50 by 0.07
4.50*0.07 = 0.315
Then the sales tax is about $0.32.
You can also do it mentally. Moving the decimal point in 4.50 once to the left gives you 10% of the original amount, 0.45. Move it again to get 1% of the price, 0.045. Then multiply this by 7 to get 7%.
Answer: -0.6

Answer:
X= -12
Step-by-step explanation:
-2x-4=20
-2x-4+4=20+4
-2x=24
x=-12
5x+y=2
4x+y=4
5x+y=2
-1( 4x+y=2)
5x+y=2
-4x-y=2
your y'all cancel out so you r left with
x=-2
then you plug the x in to one of the equations
5(-2)+y=2
-10+y=2
then add 10 to both sides
y=12
Answer: x = -2 y = 12
there's the work and all its simple you just have to figure out how to get rid of y or x ( which ever is easier) and you can figure it out after that
