Multiplicative Identity Property
Step-by-step explanation:
Percentage is out of a 100. Therefore, 35/100
Simplify 35/100
Becomes 7/20
Fraction of 35% is 7/20
32 degees, 43.8 degrees, 53.8, 63.8 Yes they are proportional
Add these eqn and then you have to cancel out (y) after that add x and 2x which is equal to 3x and also add RHS i.e.30 and divide it by 3
