Answer:
Step-by-step explanation:
angle y is 122 degree because angle y and x are supplementary angles or cointerior angles are supplementary
0.7 = 7/10 = 14/20
The missing numbers are 10 and 14
P r o p o r t i o n s
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
Answer:
-1/2
