@dkplus9 @elixir_art I love the little window shop creperies in Mykonos!

@Emily_53xl Sqrt (((9+16)/5)+4)= Sqrt ((25/5)+4)=Sqrt(5+4)=Sqrt (9)=3

@ro10261126 I want to build a tub like that for my yard so I can use it in the winter. I think a large barrel to burn wood in wrapped in copper tubing to transfer heat by siphon circulation.

@Extrovert_hu_g Easy, square both sides so 3a+4=25, 3a=21, a=7

[Marc Magnus @MarkdalgCais]

@MsCranberyjuice I am afraid I am going to have to ask you to prove it to me!

[Marc Magnus @MarkdalgCais]

@zakiaonsol Simplify m+3m=4m, divide by m, (m+3m)/m=4, 1+2m=4, 2m=4-1, 2m=3, m=1.5

[Marc Magnus @MarkdalgCais]

@DearGozde simplify to 20+16=A^2 A^2=36 A=6

[Marc Magnus @MarkdalgCais]

@linadreaamy You can simply two ways, either x+7=45/3 or 3x+21=45. I like the first as it is easier to do in my head so x+7=15, x=15-7 therefore x=8

@farman4x Simplify first 12+2x2= 12+4 = 16

[Marc Magnus @MarkdalgCais]

@farman4x Simplify first so on top it is (64-8)/8 = 56/8=7

@BklynUFOHunter @Seraphinaf5 @farman4x @renabaddie_ Pretty much only in the USA that they say "math." "Mathmatics" is plural, and shortened to "maths" in most of the rest of the world.

[Marc Magnus @MarkdalgCais]

@farman4x first simplify (8+16)/4 = 24/4=6

[Marc Magnus @MarkdalgCais]

@baharkarakrt 2x-4=8, 2x=8+4, 2x=12, x=6
5(6)+y=20, 30+y=20,y=20-30
y=-10

@Motivational__G There is no notation to indicate if the line in the middle is parallel with the top or bottom line, so my students would be required to indicate that they cannot know for sure. If it is, then 130º

@0xLuciferCore x^2/9=64, x/3=8, x=3x8, x=24

@onlyskypace sides of small square is 12m, sides of large is 13m. Area of X is 1/2 x 12 x 13 or 78m^2

[Marc Magnus @MarkdalgCais]

@onlyskypace Simple PEMDAS (or BODMAS) rules. No Parentheses nor exponents so multiplication and division next (division is a type of multiplication)
so 5+1+0-5=? Then do addition and subtractions... Answer is 1
