Well the whole ratio is 14 sooooo
98 ÷ 14 =7
for food tents it would be 9 x 7 which is 63
And for retail tents 5 x 7which is 35
so the whole ratio is 63: 35
18 points scored for a pair was 40 % of the final score
then final score is 100%
therefore if 40 % accounts for 18 points
100 % = 18 / 40% *100%
= 45 points is the final score
if we back calculate = 18 /45 *100 = 40%
Therefore the final score is 45 points
2x3=6
3x2=6
6 divided by 2=3
6 divided by 3=2
9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9
I think you basically just got to add everything up . I mean , i can already tell this is a graph question but it says perimeter so perimeter somehow means add everything up. But im still not too sure ..
