-2(5x-1)-3=10x
-10x+2-3=10x
2-3=x
x=-1
Thought I already answered this. I must have forgotten to click "add your answer."
We have similar triangle trianges ABC ~ ADE so
BC:AB = DE:AD
BC:2 = 10 : (2+3) = 10:5 = 2:1
So BC=4 because 4:2 = 2:1
Choice C.
1 Yes 2. Yes
Step-by-step explanation:
they are similar because in problem one each side is related by a factor of 3

Answer:
Pt. A: 25 cookies. Pt. B. $10.00
Step-by-step explanation:
1st you need to divide 10 cookies and $2 dollars, so 10/2= 5 cookies. So, it would be 5 cookies per dollar. So, then you would multiply 5 cookies*5 dollars, that equals 25. you would get 25 cookies for $5.00.
So, for Part B, you would divide 50 cookies by $5 dollars, and that would equal $10.00.
Hope this helped you!!! (:
