Every 6th voter gets a button. Every 7th voter gets a sticker. Which voter is the first to receive both items?

MrMuchimi

Answer:

Step-by-step explanation:

Use LCM of 6 and 7 to find a number that is the same:

6 12 18 24 30 36 42

7 14 21 28 35 42

Since 42 shows up in both, the 42th voter gets a button and sticker.

Hope this helped.

describe the relationship between n and 4 that will make the value of the expression 7× n/4 greater than 7

Norma-Jean [14]

So set up an equation!

7* n/4 > 7

So trying to get the variable alone...

n/4 > (7/7) aka 1
n> 1*4
n> 4

Try it out!

7* 6/4 = 42/4 = 21/2= 10 and 1/2

It is greater than 7
