Which number is an irrational number

zhenek [66]

Answer:

Un número irracional es un número que no se puede escribir en fracción - el decimal sigue para siempre sin repetirse. Los decimales no siguen ningún patrón, y no se puede escribir ninguna fracción que tenga el valor Pi. Números como 22/7 = 3.1428571428571... se acercan pero no son correctos.

Can you please help me?!

Nezavi [6.7K]

Answer:

d) $x=5$

Go to station 10

Step-by-step explanation:

$-\left(1+7x\right)-6\left(-7-x\right)=36$

Expand:

$-1-7x+42+6x=36$

$-x+41=36$

Subtract 41 from both sides:

$-x+41-41=36-41$

$-x=-5$

Divide both sides by -1:

$\frac{-x}{-1}=\frac{-5}{-1}$

$x=5$

You divide a number and get a remainder of 4. what 1 - digit number can the divisor of the problem?

ahrayia [7]

Answer:

Any of the numbers 5,6,7,8,9 could be the divisor of the problem.

Step-by-step explanation:

Division

If I divide a number and get a remainder of 4, then the divisor must be greater than 4. A divisor of 4, for example, would lead to a remainder of (maximum) 3.

Thus, our divisor can only be one among the numbers: 5,6,7,8,9. If the dividend is exactly 4, then the divisions

4/5, 4/6, 4/7, 4/8, and 4/9

they all produce the same remainder of 4.

Thus, any of the numbers 5,6,7,8,9 could be the divisor of the problem
