51/2 - 2 1/3 do not answer -7.83333333333

- 7

Step-by-step explanation:

Change the mixed numbers to improper fractions

5 =

2 =

- -

We require the denominators to be the same before adding

The lowest common multiple of 2 and 3 is 6, hence

= - -

= - -

= = - = - 7

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
