45(5)=225 than multiply that by 60 because remember he only swam 5 out of 7 days a week (12x5=60) therefore 225x60= 13,500 minutes to convert to hours divide by 60 which will be 225 hours
The answer would be C. 73.6. If you use the correct math without rounding it would be 73.5792. Hope this helps!
It would be 9/6 which simplifies to 3/2
9. The child is 10 years old, which leaves 37-10, which is 27. Divide 27 by three for the triplets. 27/3 is 9. The triplets are 9 years old
1. Regroup terms
x^3 - 6 * 10x^2x-8/ x-3
2. Use product rule
x^3 - 6 * 10x^ 2+1 - 8/ x-3
3. Simplify
x^3 - 6 * 10 x^3 - 8/ x-3
4. Simplify further
x^3 - 60x^3 - 8/ x-3
5. Simplify the last time
-59x^3-8/x-3
