1. Sammy reads the same number of pages from his book each night. The expression 228 – 12x shows how many pages he has left to read on any given night. What does the constant in the expression represent? the total number of pages Sammy has read so far the total number of pages in Sammy’s book <---- the number of pages Sammy reads each night the total number of nights Sammy has been reading

228 total pages and x would be total number of night he read. he read 12 pages per night
Would 228 be the constant?
Thanks for Medal:) @CrazyCountryGirl
The constant is the number that stands by itself
ammy reads the same number of pages from his book each night. The expression 228 – 12x shows how many pages he has left to read on any given night. What does the number 12 in the second term represent? the total number of pages Sammy has read so far the total number of pages in Sammy’s book the number of pages Sammy reads each night <--- the total number of nights Sammy has been reading
@IM5er101

i think its option c. the no: of pages sammy reads each night
That's what I thought too. :):):) Sammy reads the same number of pages from his book each night. The expression 228 – 12x shows how many pages he has left to read on any given night. What does the term 12x represent? the total number of pages Sammy has read so far <----- the total number of pages in Sammy’s book the number of pages Sammy reads each night the total number of nights Sammy has been reading
@mathmath333 @IM5er101 @IMStuck
You need more help?
its a. the total no of pages he had read so far , i think
12x represents the number of pages he reads per night, with x being the number of nights left he has to read.
so the choice for that last one is "the number of pages Sammy reads each night".
In some states, you pay a sales tax on items you purchase. A sales tax is a percent of what a customer pays for an item that costs c dollars. The expression 0.07(c – 0.05c) represents the amount of sales tax in a certain state that would be collected on an item that has been discounted by a certain percent. The expression has two factors. What does the factor c – 0.05c represent? the regular cost of the item the discounted cost of the item <--- the discount percent the amount of the discount

I'm not sure how to do this one.. In some states, you pay a sales tax on items you purchase. A sales tax is a percent of what a customer pays for an item that costs c dollars. The expression 0.07(c – 0.05c) represents the amount of sales tax in a certain state that would be collected on an item that has been discounted by a certain percent. The expression has two factors. What is the sales tax percent? _________ %
@mathmath333 @IM5er101 Last one. :)
@agent0smith @ganeshie8
0.07(c-0.05 c)=0.07*c-0.07*0.05 c i think its 0.07*0.05C
What's C?
c= dollars as given in the question
@mathmath333 So the final answer would be.... 0.0035?
oh yea
