Answer: 10
p = Pamela’s age, j = Jiris’ age
2j = p
p + j = 30
Then change things around a bit...
p + j = 30 or
30 - p = j
Then substitute
2(30 - p) = p
And solve
2(30 - p) = p
60 - 2p = p
60 = 3p
p = 20
0.674 means that it 674/1000
which mean that if the model consist of 1000 squares, you have to shade 674 of the squares.
If the model consist of 500 squares, you have to shade 337 of the squares ( you get the number after dividing both 674 and 1000 with 2)
Can you please add a picture of the problem or type all the measurements and information?
