**write your work, so i know you guys didn't cheat. i ain't giving brainliest to someone without one**

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

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
