Answer:

Question 8.)  Choice d.)  4 + x + 6x  = 4 + 7x

Question 9.) Choice b.)  18 - 15 + 4n + 5n  simplifies to  9n + 3

Step-by-step explanation:

For the first question, like terms are terms that have the same variables, and not necessarily the same coefficient numbers.

first problem,    x + y + xy  all have unique terms.  x  is different from y and is different from xy

so it cannot be A.

Choice d. has like terms  x and 6x  so  4 + x + 6x can simplify to 4 + 7x

Choice b.)  18 - 15 + 4n + 5n  simplifies to  9n + 3

Lelechka [254]

Answer:

Option A) is correct.

Step-by-step explanation:

The final cost of a sale item is determined by multiplying the price on the tag by 75%.

So. if the final cost is represented by $F and the price on the tag is $t, then the relation between  F and t will be  

F = 0.75t.

This relation is linear since the ratio of the change in the final cost compared to the rate of change in the price tag is constant.  

Therefore, option A) is correct. (Answer)

puteri [66]
First multiply the big numbers. 3*1.20= ($3.60) and 5*1.20= ($6) 
Now the fractions, 1/12 would equal 10 cents. 5/12 + 1/12= 6/12 which would also equal (60 cents).   3.60+6.00+.60= $10.20

You can use the alternate interior angles theorem to put XVW as 52 degrees and then add 52 and 60 up and subtract from 180 since every triangle has 180 degrees
