Answer:
500 items
Step-by-step explanation:
plug the $320000 into C
320000=500x+70000
1. substract 70000 from both sides (always get rid of adding/substracting first)
320000=500x+70000
<u>-70000 -70000</u>
250000=500x
2. divide both sides by 500 (you divide both sides by whatever number is in front of x so you can isolate it)
<u>250000/500=500x/500</u>
500=x
there you go :D good luck and have a good day

Answer:
B) -4
Step-by-step explanation:
(5/2)x + y = 2
x + (2/3)y = 4
y = 2 - (5/2)x
x + (2/3)(2 - (5/2)x) = 4
x + 4/3 - (5/3)x = 4
(-2/3)x = 8/3
-2x = 8
x = -4
Answer: Odds in favor = Number of successes: Number of failures
Step-by-step explanation:
Example
A jewelry box contains 5 white pearl, 2 gold rings and 6 silver rings. What are the odds of drawing a white pearl from the jewelry box?
Number of successes = 5
Number of failures = 2 + 6 = 8
Numbers of ways to draw a white pearl: number of ways to draw another jewelry.
5:8
The odds are 5:8
