Therefore to obtain a 1:1 ratio:

=30 candles/18 candle holders * (18/30)

Therefore she needs to buy 18 packs of candles and 30 packs of candle holders to have exactly the same number of candles and holders

Answer: x=6, y=20

Step-by-step explanation:

Since ΔBCD and ΔTUS are congruent triangles, we can set the sides equal to each other.

y=2y-20 [subtract both sides by 2y]

-y=-20 [divide both sides by -1]

y=20

--------------------------------------------------------------------------------------

3x+32=9x-4 [add both sides by 4, and subtract both sides by 3x]

36=6x [divide both sides by 6]

x=6

Answer:

$f(x - 4) = x^2 - 6x+ 8$

Step-by-step explanation:

Given

$f(x) = x^2 + 2x$

Required

Find f(x - 4)

Substitute x - 4 for x

$f(x - 4) = (x- 4)^2 + 2(x - 4)$

Expand

$f(x - 4) = x^2 - 8x + 16 + 2x - 8$

Collect like terms

$f(x - 4) = x^2 - 8x + 2x+ 16 - 8$

$f(x - 4) = x^2 - 6x+ 8$

The average of four different positive integers is 9. What is the greatest value for one of the integers?

saul85 [17]

From the given information; Let the unknown different positive integers be (a, b, c and d).

An integer is a set of element that are infinite and numeric in nature, these numbers do not contain fractions.

Suppose we make an assumption that (a) should be the greatest value of this integer.

Then, the other three positive integers (b, c and d) can be 1, 2 and 3 respectively in order to make (a) the greatest value of the integer.

Therefore, the average of this integers = 9

Mathematically;

$\mathbf{\dfrac{(a+b+c+d)}{4} =9}$

$\mathbf{\dfrac{(a+1+2+3)}{4} =9}$

$\mathbf{\dfrac{(6+a)}{4} =9}$

By cross multiplying;

6+a = 9 × 4

6+a = 36

a = 36 - 6

a = 30

Therefore, we can conclude that from the average of four positive integers which is equal to 9, the greatest value for one of the selected integers is equal to 30.
