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:
the second one. They need to be in the same order of congruency.

The answer for the question is -1.5
Answer:

Step-by-step explanation:
Let the numbers be x and y
<h3>Given condition:</h3>
x + y = 48 --------(1)
y = 7x -------------(2)
Put Eq. (2) in (1)
x + 7x = 48
8x = 48
Divide 8 to both sides
x = 48/8
<h3>x = 6</h3>
Put x = 6 in Eq. (2)
y = 7 (6)
<h3>y = 42</h3>
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
If we refer to the longest side as x and the shortest side as y and the medium side as z then we come up with this formation:
x+y+z= 22
y is shorter than x by 5 inches so y= x-5
z is longer than y by 2 inches therefore z= x-5 +2
therefore:
x+(x-5)+(x-5+2)=22
x+x-5+x-5+2=22
3x-8=22
3x= 22-8
3x=14
x=

replace x in y and z in previous formations
