X = 4y
3x - y = 70
substitute the x in the second equation with the other half of the first equation.
3(4y) - y = 70
12y - y = 70
11y = 70
y = 6.36 repeating, or 6 4/11
now use this to solve first equation
x = 4 (6 4/11)
x = 25.45 repeating
done
Answer:

Step-by-step explanation:
0.5 percent (calculated percentage %) of what number equals 12? Answer: 2,400.
Answer:
HI=JG(2)=144
The radius is half the diameter, so JG(2)=HI.
They shouldn’t have to wait for each other because they are doing everything the same.
Both 3 miles away, both start at the same time, both at current rate
157 is equal to half of the circumference...
C=2πr so C/2 is:
πr=157
r=157/π ft
r≈50 ft
