Answer:
210
Step-by-step explanation:
7:5
First add the ratios
7+5=12
Put each ratio over the denominator 12 then multiply each by the total
7/12×1260= 735
5/12 × 1260 = 525
To find how many more winners than losers
735-525= 210
Substitute 1 equation in the other
y = 2x-2 -----(1)
3y+x = 15 -----(2)
substitute (1) into (2)
3(2x-2)+x=15
6x-6+x=15
7x=21
x=3
now substitute x=3 into (1)
y =2(3)-2
y= 4
coordinates of point of intersection = (3,4)
Let Tritt's age = t & Jan's age = 2t - 3
if the sum of their ages equals 30 then..

combine terms and simplify

now simply divide

and to find Jan's age just plug 9 in


Jan's age = 15
Tritt's age = 9
