Royal Revolt 2

1- According to the problem the store had a 10% off when they applied the 15% discount, that means that they took off 15% of 90%, and that's 13.5%. So we add up the discounts: 10 + 13.5 = 23.5% out in total. Julie paid 76.5% of the original prize so we solve:
x = 306 * 100 / 76.5, and by solving that we get 400. That's what the flute originally costed.

2- Here we only have to leave the x alone just like the last time:
y(x-1) = z
x-1 = z/y
x = (z/y) + 1

3- The three angles in the inside of a triangle add up 180, so we form an equation, clear the x and solve:
15 + 85 + x = 180
x = 180 - 15 - 85
x = 80

4- Let x and y be as follows:
x: Sarah's age.
y: Her brother's age

The info we have lets us form two equations:
x = 2y (Because she's twice as old)
x = y+15 (Because the difference between them is 15)

Now we only need to form and equation with both x formulas and solve it:
2y = y + 15
2y - y = 15
y = 15. So her brother is 15 years old.

5- 1 liter = 1000 milliliters

6- The cost of \$5 is for vehicle and driver. So an extra of \$1.50 was charged. Taking in count that 50 cents are charged per person:
150 / 50 = 3. So three extra people were there. We don't have to forget the driver, so 4 people were in the vehicle.

7- The first equation lets us know the value of x:
3x + 5x = -8
8x = -8
x = -8 / 8
x = -1
So x + 1 is equal to 0.

8- We only have to clear it a bit and leave a zero alone:
x^2 + 2x = 24
x^2 + 2x - 24 = 0
Now we use factorization and get:
(x+6)(x-4) = 0
We form two equations (one for each factor) where we clear the x and get two solutions:
x+6 = 0. So x = -6 is a solution.
x-4 = 0. So x = 4 is another solution.
As the second equation, we formed is equal to the first one, Both -6 and 4 are solutions of x^2 + 2x = 24.

9- There's a 1 out of 6 probability of getting a 5, that's approximately 16.7%

10- By 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105 and 210 itself.

1. Flute costing 400, wow I could get some gems for Rr2 and be no. 1

2. Leave x and let's work on xx and x

3. By the way I see the 3 angles its to be no. 1 in RR 2.

4. Wow, x and y denote age, what's the BMI

5. Ask a nursery child this question

6. This is a cheap rental car and driver

7. The value of x is = 3000 gems from Flare

8. Factorisation is what I do with the gems given by Flare...factorisation = prioritazation

9. Yup, the probability this time is great for me to receive 750 gems for the first time.

10. Please guys start the counting.

1.  An instrument store gives a 10% discount to all students off the original cost of an instrument.
During a back to school sale an additional 15% is taken off the discounted price.
Julie, a student at the local high school, purchases a flute for \$306.
How much did it originally cost?

X - (X/100) x 15 = 306 => X = 360
Y - (Y/100) x 10 = 360 => Y = 400
The originally cost is 400

2. If y(x-1)=z then x=......

x= (z/y) + 1

3. Two angles of a triangle measure 15° and 85° . What is the measure for the third angle?

15 + 85  + x = 180 => x=80

The measure for the third angle is 80 °

4. Sarah is twice as old as her youngest brother. If the difference between their ages is 15 years. How old is  her youngest brother?

2X - X = 15 => X=15

Her youngest brother is 15 years old

5. The number of milliliters in 1 liter is.....

1 Liter = 1000 Milliliters

6. The cost to ride on a ferry is \$5.00 per vehicle and driver with an additional cost of 50 cents per passenger. If the charge to get on the ferry is \$6.50, how many people were in the vehicle?

\$6.50 - \$5.00 = \$1.50
=> 3 people

7. If 3x + 5x = -8, then x + 1 =......

3x + 5x = -8 => x = -1
=> x + 1 = 0

8. What are the solutions of this ecuation: x^2 + 2x = 24 ? (x^2 = x power 2 = x * x)

_x = 4
_x = -6

9. A die is rolled once. What is the probability of getting number 5? (in percent)

[100/6]% = 16.(66)%

10. 210 is divisible by.....

1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105,  210.

1. I actually ordered a tuba instead of flute. How am I supposed to know the price of a flute?
2. I am getting dizzy from math. It is some kind of expression with y and z.
3. A triangle is a music instrument. It makes sound and I don't know the angle.
4. Oh dear, 15 years, twice as old. I haven't had math for a while. I got it, it's a trick question, his birthday is on 29 of february, he is actually 60, so 15 now. So 60 is the answer.
5. Milli stands for 1/1000 so 0.001 is the answer
6. Don't I get a discount on that fairy?
7. X is where the treasure is buried, so do I get a second chance after a failure?
8. x^2 + 2x => 4x = -8  so, the answer must be -2.
9. 50% the dice ends on 5 or not.
10. A lot of numbers.
