Answer:
192 km
Step-by-step explanation:
the same ratios apply to the situation
if 1 cm is 8 km, 24 cm could be calculated using ratios
1/8 = 24/x
2y - 3y + y = 0
-y + y = 0
0 = 0
Hence, y has infinite possibilities of value since the equation is true without there being any use of y in it.
Hence, y could be any value.<span />
If the green suitcase is 36 pounds and the other suitcase is 10 pounds lighter than 3/4 just find what 3/4 is and subtract 10. Then you have the weight of the Blue suitcase. So the suitcase is 17 pounds. B=3/4G -10 but G =36 so B= 3/4 •36 -10 for the total just add. One is 36. One is 17. 53 pounds for both

Answer:
The UPC is not valid..
Step-by-step explanation:
The Universal Price Code is represented in the form of bars which is scanned when we purchase something.
The last digit of the UPC is the check digit.
Give UPC = 375407370090
To check whether the UPC is valid or not.
Step 1:
Add the digits at odd positions.
3 + 5 + 0 +3 + 0 + 9 = 20
Step 2:
Multiply the number obtained in step 1 by 3
20*3 = 60
Step 3:
The digits at even positions have to be added. The last digit has to be ignored as it is a check digit.
7 + 4 + 7 +7 +0 = 25
Step 4:
Add the numbers obtained in Step 2 and step 3
60 + 25 = 85
Step 5:
The number obtained in step 5 is subtracted from the next multiple of 10.
In the above case,
85 will be subtracted from 90.
90 - 85 = 5
For a valid UPC, the answer to step 5 is equal to the last digit of UPC.
In the above case, the answer is 5 which is not equal to zero.
So, the UPC is not Valid.
