This should help you here are the steps of your problem :)
2*(1/2)*r+2*r+1 = 9*(1/10) // - 9*(1/10)
2*(1/2)*r+2*r-(9*(1/10))+1 = 0
2*(1/2)*r+2*r-9/10+1 = 0
3*r+1/10 = 0 // - 1/10
3*r = -1/10 // : 3
r = -1/10/3
r = -1/30
r = -1/30
So your answer would be 1/30

Answer:
x= 48 and PMO= 55
Step-by-step explanation:
PMO= LMO so 55= x+7
x+7=55
-7 -7
x=48
Pmo = x+7 so (48)+7 = 55
Answer:
x = -4
Step-by-step explanation:
x/8 = -1/2
-1/2 = ?/8
2 * 4 = 8
-1 * 4 = -4
2 * 4 = 8
-1/2 = -4/8
x = -4
