Answer:
$159
Step-by-step explanation:
All your doing is adding 45% and a percentage is out of 100 so to put it in decimal form it would be 0.45 added onto 159 which would give you $159.45 rounded to the nearest dollar would be $159
20x^2+50 = -40x^2+110x [ Taking x as the unknown positive integer ]
m=3
Plug it in and it should work
3-2 =1 over 4 which is the same as 5 over 20 because both as a percentage equal 25% or 1/4 or 0.25 if you put it in a calculator as calculators provide decimal answers
R = {10; 15; 20}
S = {20; 25}
R U S = {10;15; 20; 25;
