Answer:
its 23/36
Step-by-step explanation:
The strategy or equation which do not solve this problem is letter A and B.
The letter A goes m=(30+45+35)/6, the question asked how many minutes Ella will babysit in six weeks. In a week Ella babysits for 110 minutes, instead of dividing it by 6 weeks (which is shown in the equation of letter A), you have to multiply by 6 weeks. It should go like this, m= (30+45+35) x 6.
Answer:
The answer is x=A-cw/b.
I need to add more characters so don't worry
Answer:
-1±i
Step-by-step explanation:
Im assuming the question is asking what the roots of x^2+2x+4=2 are.
1. x^2+2x+4= 2 - subtract 2 on both sides to set the quadratic equation equal to zero.
2. x^2+2x+2 - now, since this equation cannot be factored the quadratic formula must be used: -b±
(standard form: ax^2+bx+c)
3. -2±
/2(1)= (-2±
)/2
4. using complex numbers this can be rewritten as -1±i.
Break down the problem into these two equations;
x = -31
-x = -31
Solve for the 1st equation; x = -31
x = -31
Solve for the 2nd equation; -x = -31
x = 31
Collect all solutions
x = ±31
Check the solution
When x = -31, the original equation; |x| = -31 does not hold true. Thus, we will drop x = -31 from the solution set.
Check the solution again;
When x = 31, the original equation |x| = -31 does not hold true as well. Thus we will drop x = 31 from the solution set.
Therefore,
<u>No solution exists to this equation. </u>
