Answer:
left
Step-by-step explanation:
The question says she used 
of it, so she probably used of it. I'm assuming this is an error in the question, and it should be asking how much is left. To solve for that:
-
make denominators equal
(
× ) - ( ×

1) 200 candies
15% of my candies were strawberry candies. I had 30 strawberry candies. How many candies did i have?
-----
Let "x" be the number of candies.
----
Equation:
0.15x = 30
x = 30/0.15
---
Multiply numerator and denominator by 100 to get:
------------------
x = 3000/15
----
x = 200
---------------------------------
2) 146 STUDENTS
27%*T=54, So T=200.
So 200-54=146 Students passed the test.
---------------------------------
3) She got a 20% discount (or 80% discount). (Work shown for 80%).
First you have to find out how much Mandy paid. So from 15000 you will subtract 3000. 15000-3000=12000.
Next you need to set up your equation. . You then have to cross multiply. So 100 times 12000, 100*12000=1200000. And 15000 times x is 15000x. Finally you divide both sides by 15000. And 1200000 divided by 15000 is 80. X=80

Answer:
The answer is C.
Step-by-step explanation:
The formula to find equation is y - y1 = m(x - x1).
Let (x1,y1) be (6,2) and m is -5/7.
So the equation is,
y - 2 = -5/7(x - 6)
The small and large triangles are similar
so 3 / (3+3) = 9 / AC
9 / AC = 1/2
