Answer:

  317°

Step-by-step explanation:

The total measure of the angles around the center of the circle is 360°. The sum of angles in each half (above AB or below AB) is half that, or 180°. So, the sum of angles below the line is 180°. We can use that fact to find x, then the measures of all of the angles.

  (7x +1)° +90° +(9x -7)° = 180°

  16x = 96 . . . . . divide by °, subtract 84

  x = 6 . . . . . . . . divide by 16

Then angle AOD is ...

  (7·6 +1)° = 43°

Short arc AD is 43°, so long arc ACD is 360° -43° = 317°.

  arc ACD = 317°

Monica and Michael both want to buy a scooter. Monica has already saved $25 and plans to save $5 per week. Michael has $16 and p

3 weeks

Step-by-step explanation:

To find the number of weeks, we have to equate the amount already saved and planned to save by both each week.

So we can write the expression as,

Let w be the number of weeks.

25 + 5w =16 + 8w

Grouping the terms as,

25 - 16 = 8w - 5w

9 = 3w

Dividing both sides by 3, we will get,

3w/3 = 9/3

 w = 3

So number of weeks = 3

Solve for y. 2/3+y−1/9=7/9 Enter your answer in the box 
Novosadov [1.4K]
Adding 1/9 to both sides, we get 2/3+y=8/9. Next, 2/3 can be multiplied by 3/3 to get 6/9 due to that 3*3=9 and using the identity property. We then subtract 6/9 from both sides to get y=2/9
