Which variable expression represents the word phrase? the sum of 10 and the product of 7 and a number

10 + 7y

10y + 7

10 + (y ÷ 7)

10−7y

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

a) 7x=7
