I need help with this in 7th grade just started to learn this

99

Step-by-step explanation:

110% × 90 = 99

OR

110/100 × 90 (Simplify this)

11/10 × 90 (Divide 10 into 90 / Cross multiply)

11 × 9 = 99

110/100*90=x

11*9=x

99=x is your answer ☺️. If I'm right so,

Please mark me as brainliest. thanks!!!

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

step-by-step explanation:

this is not a question
