Determine the equation (y)
Let the steady rate be represented with r.
So, the equation (y) can be determined using:
Answer mon
Step-by-step explanation:
$2.50+3x=$9.25, if you need to work it out, then you do $9.25-$2.50. You take your answer and divide by three... whatever your solution is, equals X. There you go!
if the diameter of a circle is 15, its radius is half that or 7.5.
