Answer: 3/2x - 3 = y
Step-by-step explanation:
3x - 2y = 6
+2y = +2y
3x = 6 + 2y
-6 = -6
3x-6 = 2y
/2 = /2
3/2X - 6/2 = y
3/2x - 3 = y
Answer:
45
Step-by-step explanation:
Total score = 35 + (-10) + (-15) + 20 + 5
Total score = 35 - 10 - 15 + 20 + 5
Total score = 60 - 25
Total score = 45

3:4 = 7
3/198 = 7/x
solve for x using cross multiplying
3/198 = 7/x
198(7) = 3x
1386 = 3x
/3 /3
462 = x
Therefore, there are 462 workers.
Proof:
3/198 = 4/x
198(4) = 3x
792 = 3x
/3 /3
264 = x
264 + 198 = 462.
264 / 4 = 66
198 / 3 = 66
462 / 7 = 66
