Georgia [21]

Answer:

7 donkeys

Step-by-step explanation:

Given

A system consisting of donkeys and tourists

Heads = 50

Legs = 114

Required

Calculate number of donkeys.

Represent donkeys with D and tourists with T.

By means of identification; donkeys and tourists (human) both have 1 head.

This implies that

Number of Heads = D + T

50 = D + T ----- Equation 1

While each donkey have 4 legs, each tourists have 2 legs.

This implies that

Number of legs = 4D + 2T

114 = 4D + 2T ---- Multiply both sides by ½

114 * ½ = (4D + 2T) * ½

57 = 4D * ½ + 2T * ½

57 = 2D + T ----- Equation 2

Subtract equation 1 from 2

57 = 2D + T

- (50 = D + T)

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

57 - 50 = 2D - D + T - T

7 = D

Recall that D represents the number of donkeys.

So, D = 7 implies that

The total number of donkeys are 7

$\frac{-6xy^{3}z^5}{-36x^{2}y^{2}z^4}$

First cross out the -6 and -36. Six will go into 6 one time and 6 will go into -36 six times so we have the following after crossing out.

$\frac{-6xy^{3}z^5}{-36x^{2}y^{2}z^4}$
$\frac{xy^{3}z^5}{6x^{2}y^{2}z^4}$ <---After crossing out

Next cross out the x / x^2 which will give us the following:
$\frac{xy^{3}z^5}{6x^{2}y^{2}z^4}$
$\frac{y^{3}z^5}{6xy^{2}z^4}$ <---After crossing out

Now cross out the y^2 / y^3
$\frac{y^{3}z^5}{6xy^{2}z^4}$
$\frac{yz^5}{6xz^4}$ <----After crossing out

All that is left is to cross out the z^5 / z^4 and we are done.
$\frac{yz^5}{6xz^4}$
$\frac{yz}{6x}$ <----After crossing out and we are done.

$\frac{-6xy^{3}z^5}{-36x^{2}y^{2}z^4} = \frac{yz}{6x}$

Nat2105 [25]

Answer:

The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.

Step-by-step explanation:

The LCM of 13 AND 17 is 221

The LCM of 40 AND 60 is 120

lcm (40; 60) = 120 = 23 × 3 × 5
