Ce is the angle bisector of dcb and m
tatyana61 [14]

Answer:

We are given that ray CE is an angle bisector of angle ACD. With this, we have the equation,

mACE = mECD

Next, we look at the choices

mECD = mECB > This not possible since ray CD is between the two angles

mACE = mACD > This is still not possible since ray CE is between the two angles

mACE = mDCB > This is possible since angles ACE, ECD and DCB are complementary angles.

mECD = mACD > This is not possible since ray CE is between the two rays

The answer is the third option

I need the answers and work for both of those please
MatroZZZ [7]

Answer:

11. D. May 20

12. C. Every 70 bags

Step-by-step explanation:

11.

Mark on the calendar what days she has swimming and what days she has diving. (See picture below) Red is Swimming and blue is diving. For swimming, count by 5s. For diving, count by 3s. Find the next square that has both red and blue on it.

Therefore, she has both swimming and diving lessons on May 20th.

12.

Use least common multiples.

Count by 7s and 10s until there is a number that's the same.

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22....... You do not need to count by 2s. This is because you need to have a number that can also be counted to by 10s (a number with 10 as its factor), and 2 reaches all the multiples of 10. It is like 10 already includes 2.

7, 14, 21, 28, 35, 42, 49, 56, 63, 70

10, 20, 30, 40, 50, 60, 70

Therefore, every 70 bags will have all three items.

Please could someone help me with these questions?? brainliest for quickest!
lara [203]

Answer:

523 -61= 462

456-187=269

Step-by-step explanation:

subtract the last numbers first 3-1 which is 2 then 2-6 which is impossible so you borrow from 5 and add 10 to 2 which become 12-6 which is 6 the the first number has only 4 left because you borrowed from it which is 4 so 523-61= 462.

subtract the last number 6-7 it not possible because 6 is less than 7 so borrow from 5 then add 10 to 6 which become 16-7=9 then the second number you have 4-8 since you borrowed from 5, 4-8 is also not possible so borrow from 4 which become 14-8 which is 6 and the first number which is now 3- 1 which is 2 so all the result become 269
