80/4Sherman goes golfing every 6^\text{th}6 th 6, start superscript, start text, t, h, end text, end superscript day and Brad goes golfing every 7^\text{th}7 th 7, start superscript, start text, t, h, end text, end superscript day. If Sherman and Brad both went golfing today, how many days until they will go golfing on the same day again

They will go on golfing until 42 days on the same day again.

Step-by-step explanation:

Given:

Sherman goes golfing every 6th day and Brad goes golfing every 7th day.

If Sherman and Brad both went golfing today.

Now, to find the days until they will go golfing on the same day again.

Sherman goes golfing for every

And Brad goes golfing for every

So, to get the days until they will go golfing on the same day again find the least common multiple (LCM) of 6 and 7.

Therefore, they will go on golfing until 42 days on the same day again.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
