In −3z+6b−7, the first term is -3z. It's a variable term, since z is assumed to be a variable. The coefficient of this variable, z, is -3.
First, to estimate we can round 53.82 up to 55.00. Then you can look at it like this: when you divide 100 by 20 you get 5, so 20% is one fifth of 100. Therefore, we want to find one fifth of $55. To do this, you multiply 55*1/5. When you multiply the numerators by each other and the denominators by each other, you get 55/5. When you divide the numerator and denominator by 5, you get 11/1 or $11.
Hope this helps
So u hav two numbers one is the multiple of another (so like 2 and 4) ( it can go into the other number) then the least common multiple of the other
I think an answer would be if u do 2 and 4 the LCM would be 2 (don’t know if I’m right not sure about my LCM)
First, you must turn the 12.5% into a decimal, which would then become .125. You then multiply that by the $138.25 and you would get 17.28. Then you just add the $138.25 to the $17.28 where you would then get $155.53 as your answer. Please let me know if I am wrong.
