8 5/6 + 4 7/10

= 8 25/30 + 4 21/30

= 12 46/30

= 13 16/30

= 13 8/15

\(4\frac{11}{12}+5\frac{8}{9}\\ =4\frac{33}{36}+5\frac{32}{36}\\ =9\frac{65}{36}\\ =10\frac{29}{36}\)

25 - 1/2

= 25 - .5

= 24.5

= 24 1/2

OR

= 49/2

Good work Guest #1, but that lump of numbers though.......

pi approx = 22/7 OR 3.14

\(-\frac{2}{3}+y=\frac{1}{7}\\ y=\frac{1}{7}+\frac{2}{3}\\ \;\;=\frac{17}{21}\)

The 2 events are irrelevant.

If it's not a horse crossing the road, the road will be the same length as the horse is crossing the road.

\(\dfrac{6}{2(1+2)}\\ =\dfrac{6}{2(3)}\\ =\dfrac{6}{6}\\ =1\)

\(\sin x = 0.25\\ x=\sin^{-1}0.25\\ \;\;\approx14.47751218593^{\circ}\)

Use PEDMAS.

Notice that Division and Multiplication can be done in 1 step together. Same as Addition and Subtraction.

\(18+36\div 3+(9-6)^2\)

\(=18+36\div 3 + 3^2\)P(arentheses)

\(=18+36\div 3 + 9\)E(xponents)

\(=18+12+9\)D(ivision) and M(ultiplication)

\(=39\)A(ddition) and S(ubtraction)

\(\dfrac{3}{5r}=-2\\ 3=-10r\\ r=-\dfrac{3}{10}\)

Or you mean (3/5)r=-2?
\(\dfrac{3}{5}r=-2\\ r = 2\times \dfrac{5}{3}\\ \;\;=\dfrac{10}{3}\)

Good answer Guest #1.

Example: If you have x^2 = 25......

\(x^2=25\\ x=\pm\sqrt{25}\\ \;\;=\pm 5\\ \therefore\text{ x = 5 or x = -5}\)

Don't be lazy guys, it's an easy one!! :D

\(\dfrac{4}{7}+\dfrac{3}{14}\\ = \dfrac{8}{14}+\dfrac{3}{14}\\ =\dfrac{11}{14}\)

\(\frac{7}{3}=\frac{4}{x}\\ 7x=12\\ x=\frac{12}{7}\)

\(24-32\div 4 + 6 = 22\)

Guest #1 don't be so rude.

\(\dfrac{4|y+3|+12}{4}\\ =|y+3|+3\)

21,900,000,000 cubic kilometers. With a density of 3.34g/cm^3, it has a mass of 7.35*10^22kg.

x - 12/6 = 9

x - 2 = 9

x = 11

Or you mean (x-12)/6=9?

(x-12)/6 = 9

x-12 = 54

x = 66
