Answer:
x = 15
Step-by-step explanation:
Because PQ is parallel to JL, [tex]\frac{KP}{PJ} = \frac{KQ}{QL}[/tex]
Substituting, we have [tex]\frac{x-6}{3} = \frac{x}{5}[/tex]
5(x-6) = 3x
5x - 30 = 3x
2x = 30
x = 15
Answer:
x = 15
Step-by-step explanation:
Because PQ is parallel to JL,
Substituting, we have
5(x-6) = 3x
5x - 30 = 3x
2x = 30
x = 15

Step-by-step explanation:
Write an exponential function to describe the given sequence of numbers, assuming that the first number in the sequence corresponds to x = 0.
5.30, 180, 1080, 6480...
Answer:
[tex]y = 5(6) {}^{x} [/tex]
Step-by-step explanation:
A exponential function is represented by
[tex]y = ab {}^{x} [/tex]
where a is the vertical stretch and b is the base and x is the nth
power of x
Since the first number corresponds with zero, that means our y intercept is the first number.
This means when x=0 , y=5 so let find the value of 5.
[tex]5 = ab {}^{0} [/tex]
b to the 0th power equal 1 so
[tex]5 = a \times 1[/tex]
[tex]a = 5[/tex]
Our equation is for now
[tex]y = 5b {}^{x} [/tex]
Now let plug in 1,30
[tex]30 = 5b {}^{1} [/tex]
Divide 5 by both sides
[tex]6 = b {}^{1} [/tex]
Anything to the 1st power is itself so b equal 6.
So our equation is
[tex]y = 5(6) {}^{x} [/tex]
A library has 2000 books. There are 3 times as many non fiction books as fiction books. Write and solve an equation. PLEASE HELP ASAP!!!???
Answer:
x = fiction books
3x = nonfiction books
x + 3x = 2000
After you solve for x, (which is the number of fiction books), you can plug its value into the equation for nonfiction books (3x) and that will give you the number of non fiction books.

Which of the following are equivalent to 9x - 27?
Select ALL that apply.
9(x - 3)
3(3x - 9)
x(9x - 3)
3(3x - 7)
3(x - 9)
Answer:
1) 9(x - 3) = 9x - 27. So, 1) applies.
2) 3(3x - 9) = 9x - 27. So, 2) applies.
3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.
4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.
5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.
Step-by-step explanation:
1) 9(x - 3) = 9x - 27. So, 1) applies.
2) 3(3x - 9) = 9x - 27. So, 2) applies.
3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.
4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.
5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.
The expressions that are equivalent to 9x - 27 are:
9(x - 3)
3(3x - 9)
To determine which expressions are equivalent to 9x - 27, let's simplify each of the given options:
9(x - 3):
Expanding the expression, we get 9x - 27.
This expression is equivalent to 9x - 27.
3(3x - 9):
Expanding the expression, we get 9x - 27.
This expression is equivalent to 9x - 27.
x(9x - 3):
Expanding the expression, we get 9x² - 3x.
This expression is NOT equivalent to 9x - 27.
3(3x - 7):
Expanding the expression, we get 9x - 21.
This expression is NOT equivalent to 9x - 27.
3(x - 9):
Expanding the expression, we get 3x - 27.
This expression is NOT equivalent to 9x - 27.
Therefore, the expressions that are equivalent to 9x - 27 are:
9(x - 3)
3(3x - 9)
So, the correct options are 1 and 2.

Answer:
4 12/18, simplified is 4 6/9
Step-by-step explanation:
You change the fractions to improper fractions so 10 1/2 to 21/2 and 2 1/4 to 9/4. Since we can't divide, we change 9/4 to 4/9 and multiply. 21 times 4 is 84 and 2 times 9 is 18. Since that is an improper fraction, we have to change it to a mixed number. 18 can go into 84 4 times, and 18 x 4 is 72. 84 minus 72 is 12 so the final answer is 4 12/18 (simplified 4 6/9)
Hope this helps :)

The drama club is selling gift baskets to raise money for new costumes. During the fall play, they sold a combined 28 regular gift baskets and 24 deluxe gift baskets, earning a total of $1,188. During the spring musical, they sold 28 regular gift baskets and 13 deluxe gift baskets, earning a total of $836. How much are they charging for the different sized gift baskets?
The drama club is charging $____ for a regular gift basket and $____ for a deluxe gift basket.
Answer:
28
Step-by-step explanation:
Hi! So what we're gonna want to do here is set up a system of equations. Lets say x = regular baskets and y = deluxe baskets. You would set up the system like this:
28x + 24y = 1,188
28x + 13y = 836
So since the number before the x is the same in both equations, we are going to want to cancel that out.
28x + 24y = 1,188
-1(28x + 13y = 836)
----------------
28x + 24y = 1,188
-28x - 13y = -836
Add the two equations together! There will be no x value :)
11y = 352
y = 32... The deluxe basket is going to cost $32
Put the y value into one of the equations to solve for x.
28x + 13(32) = 836
28x + 416 = 836
28x = 420
x = 15... The regular basket will cost $15
Hope this helps!
