You have to take away 25-20.59 then divide the answer by 0.21
yes they do
they both would a ratio of 3:1
Answer:
135.5 and 47.5
Step-by-step explanation:
135.5+47.5=183
135.5-47.5=88
3:2 because 18/12 and 30/20 both reduce to 3/2
Standard form is ax+by=c
normally a is positive and a and b are integres
y=mx+b
m=slope
b=yint
y=1/2x+3
minus 1/2 x both sides
-1/2x+y=3
times -2
x-2y=-6
