Which is bigger 40% of 200 or 1/3 of 150
Gnesinka [82]
First find out what 40% of 200 is

then find out what 1/3 of 150 is
divide 150 by three, which is 50
if it was 2/3 instead of 1/3, you would multiply 50 by 2

Answer:

1 and 1/3

Step-by-step explanation:

3a² -4a +1 = 0

3a²- 3a - a+ 1= 0

3a(a-1) - (a-1)= 0

(a-1)(3a -1)= 0

a-1= 0 ⇒ a= 1

3a - 1= 0 ⇒ 3a= 1 ⇒ a= 1/3

some numbers added to -11 is 37.divide this number by -12.then multiply by -8.what is the final number?
LUCKY_DIMON [66]
Since some number added to -11 is 37, we must do 37- (-11),  which is 48. Then we check our work and find that 48+-11 is indeed 37. Now we divide 48 by -12, which is -4, multiply by -8 and get a final answer of 32.
