Which phrase best represents the following?
n
_ =7
5
1 answer:
Hey there!
“ n/5 = 7 ”
Usually whenever you have a letter value in mathematics it’s understood as a(n) UNKNOWN value; people label them as a invisible 1
~ FIRST: you have to MULTIPLY both of your SIDES by 5
1n/5 • 5 = 7 • 5
~ CANCEL out; 1/5 • 5 because that gives you a 1
~KEEP: 7 • 5 because it gives the value of your “n”
New equation: n = 7 • 5
7 • 5 = 35
Answer: n = 35 ☑️
Regular division problem: 35/5 = 7 so this makes it true!
Random fact; math actually repeats a lot.. so it can become easier for you to understand or tackle problems like this on your own!
Good luck on your assignment and enjoy your day!
