Answer:
5. is the answer
Step-by-step explanation:
I think....
x is the radius of your circle
x+7 is going to be your hypotenuse
that’s all i remember
We could solve for 'x' in the 2nd equation and then plug that into the first equation for 'x' and solve for 'y':
Subtract 6y to both sides:
Divide -2 to both sides:
Plug in 3y + 17 for 'x' in the first equation:
Distribute 5:
Combine like terms:
Subtract 85 to both sides:
Divide 17 to both sides:
This is the y-coordinate of the solution.
Answer:
2.66 days
Step-by-step explanation:
We know that a day has 24 hours, so if Roger sleeps 3/8 of a day that means that he sleeps 3/8 • 24 which equals to 9 hours.
Now we want to know how many days it takes Roger to sleep an equivalent of a day if he sleeps 9 hours a day. So:
24 h / 9 h = 2.66 days
Of course we can do it in an easier way, in fractions:
1 : 3/8 = 8/3
8/3 = 2.66 days
