Hello!
You first have to find the scale factor between the triangles
To do this you divide the new side length by the old one
9 / 6 = 1.5
They multiplied the smaller triangle by 1.5 to get the bigger one
Do this to find the missing length
8 * 1.5 = 12
The answer is 12
Hope this helps!
Answer:
Step-by-step explanation:
The problem statement defines the variables and gives the relations ...
2b + f = 8 . . . . total cost on Monday
3b + f = 11 . . . . total cost on Tuesday
__
Subtracting the first equation from the second, we get ...
(3b +f) -(2b +f) = 11 -8
b = 3 . . . . . simplify
Substituting this into the first equation, we can solve for f
2·3 +f = 8
f = 2 . . . . . . . subtract 6
Bagels cost $3 per dozen; the delivery fee is $2.
