• 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?
• What is a quotient?
• A quotient is the answer to a division problem!
• 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?
• i can,t do it crying right now
• I think you divide the total amount of money they have, by the number it costs for one.

ex. 100\$ and 2\$ per item.

(100/2=50 | 50 = # amount of items that can be bought)
• 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.
• Anyway how is ya'll day going?
