Answer:
11
Step-by-step explanation:
so we just make a system of equations:
x+y=36
say that x is the larger and y is the smaller
x-3=2y
so we can combine the equations and solve for x and y
re-arrange x-3=2y to be x=2y+3
x+y=36
x=2y+3
insert the value for x into x into x+y=36
2y+3+y=36
3y+3=36
y=11
now insert that back into x+y=36
11+x=36
x=25
Out of the two numbers x and y, 11 is the smaller number
Hope that helps :)
Answer:
Step-by-step explanation:
Corresponding sides of these triangles are proportional, so you have ...
x/5 = 20/x
x² = 5·20 . . . . . . . cross multiply
x = √100 = 10
and ...
y/15 = 5/y
y² = 15·5 . . . . . . cross multiply
y = √75 ≈ 8.7
