Please solve 5x - 1/4 = 3x - 5/4
Answers
Answer 1
Answer:
subtract 3x from 5x getting 2x so your new equation is: 2x-1/4=-5/4 then you add 1/4 to -5/4 getting : 2x=-1 the you divide both sides by 2 so x=-1/2
Answer 2
Answer:
5x - 1/4 = 3x - 5/4
5x - 3x
2x - 1/4 = -5/4
2x = -5/4 + 1/4
2x = -1
2x/2 = -1/2
x = -1/2
5x - 3x
2x - 1/4 = -5/4
2x = -5/4 + 1/4
2x = -1
2x/2 = -1/2
x = -1/2

so it asks you to use the quadratic formula which is when you have ax^2+bx+c=0 then you put it into the quadratic formula which is x=((-b+-√(b^2-4ac))/(2a))
so 8x^2+3x=-7
add 7 to both sides
8x^2+3x+7=0
put into the quadratic formula
8x^2+3x+7=0
ax^2+bx+c=0
x=((-b+-√(b^2-4ac))/(2a))
x=((-3+-√(3^2-4(8)(7)))/(2(8)))
solve inside of square root first
3^2-4(8)(7)=pemdas 9-4(8)(7)=9-224=-215
so -3+-√-215
we know that square root of negative is not real and is immaginary so i must be involved
√-1=i so
-215=i√215
so the answer is A
CONTINUATION
i√215=i(15)=15i
-3+-15i means -3+ or minus 15i
then solve for botom part
2(8)=16
(-3+-15i)/16
so the answers are (-3+15i)/16 and (-3-15i)/16
so 8x^2+3x=-7

8/20 in simplest form is: 2/5
Answers
We can just divide the two numbers.
13/20 = 0.65
Where 100% = 1
So 65%
13/20 = 0.65
Where 100% = 1
So 65%
To do this we have to see how many times 20 goes into 100. The answer is 5. So we have to times 13 by 5. The answer is 65%
