Can someone me with a few of these questions

15x, 35x+75y, , 5+c

Step-by-step explanation:

When we have unknown amounts, we use a variable to write a term.

Books cost $6.25 each plus a shipping & handling fee of $8.75 for a total of $15. We use a variable like x to represent how many books we order at $15. So 15x.

We do the same for chairs and sofas. Each chair costs $35 so we write 35x. Each sofa costs $75 so we write 75y. We add together for 35x+75y

We write expressions based on situations or just descriptions. n divided by 7 is and 5 more than c is 5+c.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
