I am in need of assistance.

A. x = 6.08, x = -0.58

Step-by-step explanation:

1. Factor the denominator.

2. Multiply the leftmost fraction by (x-6)/(x-6) to get common denominators.

3. Simplify.

4. Combine like terms.

5. Multiply the right side of the equation by (x-4)/(x-4).

6. Simplify.

7. "Cancel" out the denominators because they are equivalent.

8. Set the equation equal to 0.

Quadratic formula:

9. Factor using the quadratic formula.

10. Multiply and simplify.

11. Plug this into your calculator and solve for x.

The correct answer is A. x = 6.08, x = -0.58.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg
