Wanda cycled a total of 8 kilometers by making 2 trips to work. How many trips will Wanda have to make to cycle a total of 12 kilometers? Assume the relationship is directly proportional.

3

Step-by-step explanation:

well, if she cycles 8 kilos in 2 trips, then 1 trip would amount to 4 kilos, so therefore, 3 trips would equal 12 kilos

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
