X has to be higher than 1. 5-3 is 2, which is equal to two but not greater than. X cannot be less than 1. To show this in an inequality:

x $\geq$ 1

$x-3\geq2 implies x \geq 3+2
hence x \geq 5$ .

this means x has smallest value 5.

THE SMALLEST VALUE OF 5X will thus be 5 * 5 = 25

Can someone tell me how to do it, i have more problems like this

BigorU [14]

Answer:

$\large\boxed{\dfrac{7n}{30}=\dfrac{7}{30}n}$

Step-by-step explanation:

$\dfrac{2n}{5}+\left(-\dfrac{n}{6}\right)=\dfrac{2n}{5}-\dfrac{n}{6}$

To subtract both fractions we need a common denominator.

$LCD=(5)(6)=30$

$\dfrac{2n}{5}=\dfrac{2n\cdot6}{5\cdot6}=\dfrac{12n}{30}\\\\\dfrac{n}{6}=\dfrac{n\cdot5}{6\cdot5}=\dfrac{5n}{30}$

Therfore

$\dfrac{2n}{5}-\dfrac{n}{6}=\dfrac{12n}{30}-\dfrac{5n}{30}=\dfrac{12n-5n}{30}=\dfrac{7n}{30}=\dfrac{7}{30}n$

Solve the system if possible by using Cramer's rule. If Cramer's rule does not apply, solve the system by using another method.

Answer:

D = 0 , Dx = 4 , Dy = -6 , Dz = 2

Step-by-step explanation:

As per<u> cramer's rule</u>,

D = | 7 6 4 | = 0

| 3 3 3 |

| 4 4 4 |

Dx = | 10 6 4 | = 4

| 1 3 3 |

| 2 4 4 |

Dy = | 7 10 4 | = -6

| 3 1 3 |

| 4 2 4 |

Dz = | 7 6 10 | = 2

| 3 3 1 |

| 4 4 2 |
