Answer:
1/30=x/180
Step-by-step explanation:
The way that Ronnie wrote his proportion is wrong since 180/x is saying that he will miss 180 days of school. The fraction 1/30 means that he would miss 1 day out of 30 days, which is correct. But the fraction 180/x would mean that he is missing 180 days of school, which is wrong.
Solving:
1/30=x/180
180/30=6
1 x 6 = 6 days
He will miss 6 days of school in 180 days.
The sides of a rhombus are equal length, so you have
... 5x + 20 = 6x + 10
... 10 = x . . . . . . . . subtract 5x+10
Then the side lengths are
... 5·10 +10 = 70
