Answer:
let ratio be 3x,11xand13x
perimeter=298cm
3x+11x+13x=298
27x=298
x=298/27=11approax
shortest side=3×11=33
Step-by-step explanation:
you are right .
1. 0.25. This is because if you have -18.75 and then you add 20 to it you would be left with 0.25.
2. -1.25. This is because if you add AM and Noon together you would get that answer.
3. 14.1. If you do 1.43 + 12.67 then you would get that answer.
direct variation
y = kx
substitute in and solve for k
14 = k(-4)
14/-4 =k
k = -7/2
y = -7/2 x
y = -7/2 * -6
y = 42/2 = 21
