The answer 
<span>2x - y + z = -3          (1)
2x + 2y + 3z = 2       (2)
3x - 3y - z = -4          (3)

</span> (1) - (2)              3y +2z =5
 3 .(1) - 2.(2)       3y+5z = -1<span>

let 's solve 
</span>3y +2z =5
3y+5z = -1<span>
z= - 2, and 3y =5+4=9,  y=3, so  </span>2x - 3 -2 = -3 implies x= 1
<span>
finally x=1, y=3 and z= -2
proof 
</span>2x - y + z = -3??     2.1 - 3 -2 = -3  (true)<span>

Countering a cost $9.40 per sales tax. After sales tax, it cost $9.87. What is the sales tax rate?
Nady [450]
STEP 1:
find the sales tax (decimal form)

x= sales tax

Cost + (Cost * Sales Tax)= Total
plug in known numbers

$9.40 + ($9.40 * x)= $9.87

9.40 + 9.40x= 9.87
subtract 9.40 from both sides

9.40x= 0.47
divide both sides by 9.40

x= 0.47/9.40

x= 0.05 sales tax decimal form


STEP 2:
find sales tax percentage

= 0.05 * 100
or move decimal to the right two decimal places

= 5% sales tax percent form


ANSWER: The sales tax is 5% (or 0.05 in decimal form)

Hope this helps! :)

How is this supposed to be solved, i don’t really understand.
dezoksy [38]

Answer:

$2561.99 a quarter

Step-by-step explanation:

Just add together what they pay every year, then multiply by 25.5% (because that's the quarterly premium.)

Annual cost = insurance + dental + vision

                    = 8900 + 772 + 375 = $10047 a year.

Quarterly cost = 25.5% of annual cost

   Whenever you see of, think of multiplication!

   25.5% = .255

Quarterly cost = .255 * 10047 = <u>$2561.99 a quarter</u>
