• What is a quotient?
• A quotient is the answer to a division problem!
• if this guy could just explain how to do it instead of all the extra i wouldnt be so confused.
• you dare insult this random guy's teaching abilities?
• I still need help because i got a question its 10 less than j is 35.like what dose that supposed to mean?
• ★To model, (to write), the equation for…
"Ten less than j is 35"

Ten less than
means to subtract 10

Ten less than j
means to subtract 10 from j

j - 10 is 35
"is" means equals

so…
Ten less than j is 35
=
j - 10 = 35 ←equation made!

Needs to be with j isolated,
(to equal j)…

j - 10 = 35
=
j -10 +10 = 35 + 10
=
j = 35 + 10 ←equation = j
=
j = 45

(≧▽≦) I hope this helps!

• :( im stressed out now
• its very confusing its not helping with my problem!
• what is your problem exactly?

• For the question 'Write an equation to represent the following statement.
The quotient of 36 and 3 is j.' I put 3 x _j_ = 36.
Then it said 'wrong. The answer is 36/3 = j."
Isn't that the same thing?
• While the equations are equivalent, it does not directly interpret the words. Quotient is divide, and you show no divide, verbs are generally =, and j is isolated on the right. You did not represent the statement, you changed the equation for some reason.
• At Sal says divide by 8.5.Don't you need to multiply?

• Actually, you need to divide because that's how to get p by itself.
• p is x when xxx=x+1 p is called the plastic ratio
• is product multiplication or division

• A product is when two or more numbers are multiplied together. For example, when 12 and 5 are multiplied together, the product is 60.
