Answer:

1. x = -7

2. x = 6/13

3. x = 7/12

Step-by-step explanation:

1. x = 21 / -3

x = -7

2. 13x = 6

x = 6 / 13

x = 6/13

3. -12x = -7

x = -7 / -12

x = 7/12

By selling old CD Sarah has a store credit of $153 a new CD cost $18 what are the problem numbers of new cCD Sarah can buy
DiKsa [7]
Rileyflipflop, \frac{153}{18} = 8 \frac{1}{2}, since she can't buy half a CD, she's limited to no more than 8 CDs. If x = the cost of one CD, then x CDs cost $18x. Since we are limited to $153, our equation looks like... 18x < 153x < 8 \frac{1}{2} Again, since we can't buy half a CD, your answer should actually be... x ≤ 8 since we can buy 8 CDs or fewer.

Over the last 3 years, salesperson A has earned twice as much as salesper B who in turn has averaged 50% more than salesper C. T
bekas [8.4K]
<span>A has earned twice as much as B so: A=2B
B has averaged 50% more than C so: B=C+0.5C
Combined is 220K, So A+B+C=220,000

The last equation can be re-written as:
2B+1.5C+C=220K
AND since A=2B, it can be rewritten again as:
3C+1.5C+C=220K

Now you can get C finally, since B=1.5C you can get B, then to get the average, just divide that by 3 (years) and you should be done.
So B = 60000 for 3 years</span>
