3a-13=47 a= pls ive been stuck on this for an hower

3a-13=47

   +13 +13                 (You add 13 to both sides)

3a=60

/3    /3                     (Then, divide by 3 to both sides)

a=20

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.
