What about it. anything spesific?
If a ratio of skiers and snumboarders is 1:2, and if there are 1250 snowboarders more than skiers, it means that is that there 2500 snowboarders and 1250 skiers.
How to check it? 2500 is 1250 more than 1250 and the ratio is still 1:2 (there are two times more snowboarders than skiers). Both conditions are fulfiled, so it's correct.
Answer:
A.
Step-by-step explanation:
The sum of angles of a triangle is 180. if you add 85+45+60 you get 190. That is more than 180.
Just solve the equation, x + 0.15x + 0.06x = 15
1.21x = 15,
x = $12.39 (nearly)
I would do 12 x 10 = 120
to compensate do 120 - 12 =108 same as 12*9 = 108
The estimate is decent, because we are only $12.00 from the real answer.
