Answer:
124250cm, 1242.5m or 1.2425km
Step-by-step explanation:
0.6% = 6/100
6/100 = 0.006
0.006*1.25 = 0.0075
1.25km = 1250m = 125000cm
0.0075km = 7.5m = 750cm
125000 - 750 = 124250
Therefore:
The answer is 124250cm, 1242.5m or 1.2425km

Y + 4/9 = 2/3
Let's convert 2/3 into 6/9 so it will be easier to subtract.
Y + 4/9 = 6/9
Subtract 4/9 on both sides.
Y = 2/9 Hope this helps!
Answer:
The length of each red rod is 10 cm and the length of each blue rod is 14 cm
Step-by-step explanation:
Let
x ----> the length of each red rod in centimeters
y ----> the length of each blue rod in centimeters
we know that
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is the point (10,14)
see the attached figure
therefore
The length of each red rod is 10 cm and the length of each blue rod is 14 cm
