Answer all questions plzz.. 2/2^2 3^4/3^4 3k^2/7k 7n^4 * 4n

Ilya [14]

Answer:

1. 1/2 or .5 (same thing)

2. 1

3. -4k

4. 28n^5

Step-by-step explanation:

2/2^2 → 2/4 = .5

3^4/3^4 → 81/81 = 1

3k^2/7k = -4k

7n^4 x 4n = 28n^5

At a historical landmark, candles are used to simulate an authentic atmosphere. A volunteer is currently putting new candles in

myrzilka [38]

Answer:

Each small candleholder holds 3 candles, and each large one holds 5 candles.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of candles that a small candleholder holds.

y is the number of candles that a large candleholder holds.

24 small candle holders and 3 large candle holders, using a total of 87 candles.

This means that

$24x + 3y = 87$

Simplifying by 3

$8x + y = 29$

$y = 29 - 8x$

14 small candle holders and 7 large candle holders, for a total of 77 candles.

This means that $14x + 7y = 77$

Simplifying by 7

$2x + y = 11$

$y = 11 - 2x$

Since $y = 29 - 8x$

$11 - 2x = 29 - 8x$

$6x = 18$

$x = \frac{18}{6}$

$x = 3$

$y = 29 - 8x = 29 - 8*3 = 29 - 24 = 5$

Each small candleholder holds 3 candles, and each large one holds 5 candles.

Find the gradient from this equation 2x + 5y = 1

slega [8]

Answer:-2/5

Step-by-step explanation:

Now the above equation can be rewritten as 5y= -2x+1

Dividing this expression through by 5, we have 5y/5 = -2x/5 + 1/5

y= (-2/5)x + 1/5

Comparing with the general equation of a line;

y = mx + c; m= gradient; C= constant along the y-axis

m= -2/5
