Answer:
The side length is 11 ft
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
121 ft^2 = s^2
Take the square root of each side
sqrt( 121 ft^2) = sqrt(s^2)
11 ft = s
The side length is 11 ft

Answer:
y = -5x + 4
Step-by-step explanation:
slope = -5x
y-intercept = 4
y = mx + b --> slope intercept formula
y = -5x + 4 --> final solution
To determine the cost of each item, we need to set up equations. From the problem statement, we have three unknowns so we need three equations. We set up equations as follows:
let x cost of small pizzas
y cost of soda
z cost of salad
two small pizzas, a liter of soda, and a salad cost $14
2x + y + z = 14
one small pizza, a liter of soda, and three salads cost $15
x + y + 3z = 15
three small pizzas, a liter of soda, and two salads cost $22
3x + y + 2z = 22
Solving for x, y and z, we will have:
x = $ 5
y = $ 1
z = $ 3
