That is a direct division, if you are confused by the decimal point, lets get rid of it! We can get rid of the decimal point multiplying the upper and lower parts of the division by 10, lets do it:
<span>62.8 / 3
= 10*</span><span>62.8 / 10*3
= </span><span>628 / 30
we can try to reduce the fraction dividing by 2 the upper and lower parts:
= 314/15
and now we have to make the operation:
= 20.93</span>
Answer:
7/2 and 3
Step-by-step explanation:
using quadratic formula
{-(-13) +- √(-13)^2 - 4(2)(21) } /2(2)
-(-13)+1 / 4 = 7/2
-(-13)-1 / 4 = 3
Step-by-step explanation:
So, if 10 cookies cost 2 dollars multiply that by 2 to get 20 cookies ( 4 dollars )
Then divide 2 in half because you need 5 more cookies to get the total 25.
( 1 dollar. )
So that will cost 5 dollars! I did the math myself.
I hope this helped!
I would appreciate it if you gave me a Thanks and a brainliest (:
