Who walks faster if hichman walks 84 feet in 7 seconds or Brittany who walks 110 feet in 20 Second

Hichman will walk faster.

Step-by-step explanation:

Hichman walks 84 feet in 7 seconds and Brittany walks 110 feet in 20 Second.

We need to say who walks faster.

For Hichman,

Distance, d = 84 feet and time, t = 7 s

Speed,

For Brittany,

Distance, d = 110 feet and time, t = 20 s

Speed,

It can be seen that speed of Hichman is 12 ft/s and the speed of Brittany is 5.5 ft/s. It is clear that the speed of Hichman is more than that of Brittany. Hence, Hichman will walk faster.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
