Answer:
258
Step-by-step explanation:
Set up the two equations needed (x is the adult tickets and y is the student tickets)
x+y=372
6x+2y=1776
Solve by elimination
-2(x+y=372)
=-2x-2y=-744
Cancel like figures:
-2x-2y=-744
6x+2y=1776
= 4x=1032
x=258
I think the answer would be 1:2 because 15 is half of 30 so the simplest form is a half
The lesser of the numbers given are -16 because -16 is more negative.
Answer:
△PQR and △XYZ are similar but not congruent.
Step-by-step explanation:
When Maria dilated the triangle the size changed and so they can't be congruent. But it wouldn't have changed it's shape, so it'll be similar.
Answer:
The third number is 84
Step-by-step explanation:
Given two numbers as 13 , 85
To make the triangle to be right angle , Pythagoras theorem is applied ,
i.e H² = P² + B²
Here H = 85 ,
Let perpendicular = x and base = 13
So, P² = H² - B²
Or, x² = 85² - 13²
Or, x² = 7225 - 169
Or, x² = 7056
i.e x = = 84
Hence, the third number to make it right triangle = 84 Answer
