Answer
351.9
Step-by-step explanation:
Circumference is pi times diameter. so take 28 times pi times 4 to get the distance of going that circumference 4 times.
Algebra emerged at the end of the 16th century in Europe.
5-y/2 = 9
First, we do the inverse operation and subtract 5 from both sides.
5 - y/2 = 9
-5 -5
-y/2 = 4
Now, we do the inverse operation ( multiply by the reciprocal)
-y/2 = 4
-y/2 * -2 = 4* -2
y= -8
y=-8
Now we have our final answer: y=-8
Check our work
5 - - 8/2= 9
5+4=9
9=9
OUR ANSWER IS CORRECT! :)
