Answer:
5/42
Step-by-step explanation:
To solve this problem, you have to divide 7 and 5/6 to find the unit rate (how much hours it takes to do one task).
- Write what you know into a ratio
<u>7 tasks</u>
5/6 hour
2. You want to know how many hours one task takes, so make that a ratio as well.
<u>7 tasks </u> <u> 1 task</u>
5/6 hour ? hour
Ask yourself what do you do to the 7 in the numerator to get to one.
That's right! you divide by 7! And whatever you do to the numerator you do to the denominator (and vise-versa). Therefore if you divide the numerator(7) by 7 to get 1, you divide the denominator (5/6) by 7 as well.
5/6 divided by 7 is 5/42 meaning it takes the robot 5/42 hour to complete one task.
<u>1 task</u>
5/42 hour
Let Q be the point (a, b). Since the midpoint of P (2, 3) and Q (a, b) is (4, 6), we have
(2 + a)/2 = 4
(3 + b)/2 = 6
Solve for a and b :
(2 + a)/2 = 4
2 + a = 8
a = 6
(3 + b)/2 = 6
3 + b = 12
b = 9
So the coordinates of Q are (6, 9).
(5b^2 - 3b + 2) + (2b - 4)
Just expand out all the brackets
5b^2 - b - 2
