Answer:

1/3

Step-by-step explanation:

Turned 20 minutes, so the minute hand turned 20 times per hour

There are 60 minutes in 1 hour, so the minute hand turns 60 times per hour

Therefore, the fraction is 20/60, simplified to 1/3

A student was required to multiply a number by 4 and add 6 to it. Instead he added 6 to it first and then multiplied by 4. What

GalinKa [24]

Answer:

The correct answer is 18

the correct expression is $(4n+6)$

Step-by-step explanation:

let the number be n

therefore if he is required to multiply n by 4 and added to 6 we have

$(4n+6)= 0-----1$

given that he did otherwise by adding 6 to n and multiply by 4 we have

$(n+6)4= 36------2$

Firstly we need to solve for n in equation 2

$4n+24= 36\\4n= 36-24\\4n= 12\\$

Dividing both sides by 4 we have

$n= \frac{12}{4\\}\\n= 3$

In order to solve for the correct answer let us input n=3 in equation 1 we have

$=(4n+6)= 0-------1\\=(4*3+6)= 0\\=(12+6)=0\\= 18$
