Question

a number multiplied by 7 is 42​

Answer 1

$\huge \star \; \bf \underbrace {ANSWER} \: \star$

‣ Given :

$\textsf {A number multiplied by 7 gives 42}$

‣ To Find :

$\textsf {The number}$

‣ Solution :

$\textsf {Let the number be x}$

$\textsf {So,}$

→ $\sf {x × 7 = 42}$

→ $\sf {7x = 42}$

→ $\sf {x = \frac {42}{7}}$

→ $\sf {x = 6}$

$\implies \textsf {\underline {Hence, the number is 6.}}$

Answer 2

Answer:

answer is 8

Step-by-step explanation:

you can think of factors as the number that you multiple to get another number.

in this case 2,3,6, and 7 are all number you can multiple to get another number to get 42.

so, they are all factors of 42

however, they are not all the factors of 42.

start with 1

1* 42 = 42

factors : 1...42

try 2

2* 21 = 42

factors : 1,2...21,42

try 3

3 * 14 = 42

factors : 1,2,3,...14,21,42

try 4

4* no whole number can be multiple by 4 to get 42 , so we skip it.

try 5

5* no whole number can be multiple by 5 to get 42 , so we skip it.

try 6

6* 7= 42

1,2,3,6,...7,14,21,42

since there are no whole number between 6 and 7 , all of the positive factors have been found .

all of the number above can have thier sign and will continue to be factors of 42

1,2,3,6,7,14,21,42 -1, -2, -3, -6, -7, -14, -21, -42

2¹* 3¹* 7*¹

2's exponent : 1+1= 2

3's exponent : 1+1 = 2

7's exponent : 1+1 = 2

2*2*2= 8

confirm that 42 has 8 factors :

1,2,3,6...7,14,21,42

i hope i help you
