Answer:
Step-by-step explanation:
Girls:Boys = 3 : 2
Total students = 25
Girls = (3/5) * 25 = 15
Boys = (2/5) * 25 = 10
10 total pieces of the pie
-5
-2
And only 3 remained so your answer would be
3/10
The answer would be x=0, 2i, -2i
Answer:
The Answer is 3 - sqrt7
Step-by-step explanation:
2/3 + sqrt7 the starting equation
You multiply it by the conjugate which is 3 - sqrt7
= 2(3 - sqrt7) / (3 + sqrt7) (3 - sqrt7) the equation after you multiply by 3 - sqrt7
(3 + sqrt7) (3 - sqrt7) = 2
= 2(3 - sqrt7) / 2 the equation after you simplify (3 + sqrt7) (3 - sqrt7)
Divide out the 2's
= 3 - sqrt7/1 the equation after you divide out the 2's
= 3 - sqrt7 is THE ANSWER
