Answer:
1 < x < 19
Step-by-step explanation:
Triangle Inequality Theorem
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
We are given the measures y=10, z=9. The third side must satisfy:
10 - 9 < x < 10 + 9
1 < x < 19
Answer:
3
Step-by-step explanation:
Both angles are congruent because they are opposite exterior angles.
6x+2=x+17
5x=15
x=3
Answer: Let x represent the cost of one of Tanya's items.
Then the cost of one of Tony's items =x - 2.25. But we have:
3x =4(x - 2.25)
3x =4x - 9 subtract 3x from both sides
0 =x - 9 add 9 to both sides
x=$9 The cost of one of Tanya's items
27 Total cost of Tanya's 3 items
2.25 =$6.75 cost of one of Tony's items.
27 Total cost of Tony's 4 items.
3 x 6.75 =$27. This shows that both Tony and Tanya spent the same amount of money.

If im wrong pls tell me!
Maybe it’s 3 but it actually depends on the equation . . .
