20 less than12 times a number is 64, what is the number
Genrish500 [490]

20  <  12  ⋅  <em>x</em>  =  64

This is somewhat of a false equation though, due to  the left side  "20"  is not less than the right side  "12 ", which means that the given statement is false.

So I switched it up and made the variable "12"

<u>12  <  20  ⋅  </u><u><em>x</em></u><u>  =  64 </u>

12x - 20 = 64

12x = 64 + 20

12x = 84

12x⁄12 = 84⁄12  

x = 7

I hope this helps, as always. I wish you the best of luck and have a nice day, friend..

How do I find the value of y?
Genrish500 [490]

Answer:

y = 27

Step-by-step explanation:

line segment BA and CD are congruent, turn them into an equation

3y - 59 = y - 5

subtract 1y from both sides, you get 2y - 59 = -5

then, add 59 to both sides and the equation is now 2y = 54

divide each side by 2 and you get the value of y (y = 27)
