i need to write an algebraic expression for each word phrase. Can you check if I am correct:
2) 13 less than a number q
i got : 13 - q
4) the quotient of a number n and 4
i got: n/4
6) the number of days in w weeks
n * w
8) the cost of p photocopies if each one costs $ .15
$.15 * p
2 is wrong.
You can also write 6 and 8 as
nw
$0.15p
for #2 it should be q - 13 is that right.
for # 6 is 7*w ok
2 -- right.
Check with your teacher about 6 and 7.
Great effort! Let's go through each question and check if your answers are correct:
2) "13 less than a number q" means you are subtracting 13 from the number q. So the correct algebraic expression is q - 13.
4) "The quotient of a number n and 4" means you are dividing the number n by 4. So the correct algebraic expression is n/4.
6) "The number of days in w weeks" means you are multiplying the number of weeks w by the number of days in a week, which is 7. So the correct algebraic expression is 7w.
8) "The cost of p photocopies if each one costs $0.15" means you are multiplying the cost per photocopy, which is $0.15, by the number of photocopies p. So the correct algebraic expression is 0.15p.
So, the revised algebraic expressions are:
2) q - 13
4) n/4
6) 7w
8) 0.15p
Keep up the good work!
