Answer:

the error(s) is from the step 2

Step-by-step explanation:

3r - 12 = 2r - 3  +4r

3r - 4r -2r = 12 - 3

-3r = 9

r = 9 : (-3)

r = -3

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

In parallelogram SAVE, the value of the angle is m∠SEV = 125° while in parallelogram MORE ∠MOR = 111

<h3>What is a parallelogram?</h3>

A parallelogram is a quadrilateral with equal opposite and parallel sides. Opposite angles are equal.

In parallelogram SAVE:

m∠VAS = m∠SEV

3x - 5 = 2x + 15

x = 20

m∠VAS = 3(20) - 5 = 55 degrees

m∠VAS + m∠SEV = 180 (consecutive interior angles)

55 + m∠SEV = 180

m∠SEV = 125°

In parallelogram MORE:

∠MOR + ∠ORE = 180 (consecutive interior angles)

4x - 5 + 2x + 11 = 180

x = 29

∠MOR = 4(29) - 5 = 111

In parallelogram SAVE, the value of the angle is m∠SEV = 125° while in parallelogram MORE ∠MOR = 111
