Answer:

x=52

Step-by-step explanation:

since its an isosceles triangle, both sides are to have the same length.

so x+10+x+10+3x=180(all angles added in a triangle gives 180)

5x+20=180

5x=180-20

5x=160

x=160/5

x=52

All triangle have 180 degree
isosceles = 2 equal angle
x + 10 + x + 10 + 3x = 180
5x + 20 = 180
5x = 160, x = 32
Plug in 32 for angle U
3(32) = 96
Solution: angle U = 96 degrees

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.
