PLEASE HELP Write an equation for the following problems and then solve:
1. Five times a number added to twelve is nine times the number.
2. Twice the difference of a number and six is the sum of that number and two.
3. Four times a number is three times the difference of that number and one.

The number is 3.

Step-by-step explanation:

5x3=15+12=27

9x3=27

Hope this helps

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
