Answer:

1/2 + 1/3 = 5/6

Step-by-step explanation:

you would take a common denominater which in this case is 6 as it is a multiple of both 2 and 3.

you would multiply times 3 for the first fraction ad then by 2 in the second fraction. Both on the denominator and the numerator.

\frac{1}{2}  which   becomes    \frac{3}{6}  and     then \frac{1}{3} which       becomes  \frac{2}{6}.

3/6 +2/6 = 5/6

What is (-m)⁻³n if m = 2 and n = -24?
Galina-37 [17]

Answer:

-3

Step-by-step explanation:

(-2)^-3 x (-24)

(-2)^3 becomes 1/(-2)^3 in order to make the negative exponent a positive one.

then, you do 1/-8 (the -8 is the (-2)^3 simplified) x -24

1/-8 x (24) = 24/-8 = -3.

Hope this helps! :)

What is the result when −2/3 subtracted from −14/15?
disa [49]

Step-by-step explanation:

14/15 - 2/3 =

14/15 and 2/3 lcm is 15

so 14/15 becomes 14/15

- 2/3 become 10/15

15÷5=3 and 10÷5=2

so 14/15

-10/15=4/15

14-10 = 4

answer is 4/15 and since 15 can't be divided by 4 equally it is in simplest form at 4/15

Are the equations sometimes, always, or never true?
AURORKA [14]
15 + 2x - 4 = 9x + 11 - 7x
2x + 11 = 2x + 11
always true

2x + 3(4x - 1) = 2(5x + 3) + 4x
2x + 12x - 3 = 10x + 6 + 4x
14x - 3 = 14x + 6
never true
