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
Step-by-step explanation:
step 1. x + 4.75 - 6.55 = 5.43
step 2. looks like b is the only answer.
m pq = 2 Have a good day! sorrey if i'm wrong
Answer:
The slope is -4 over -5
Step-by-step explanation:
Your equation should be y2-y1 over x2-x1. At first you will get -8 over -10 then you simplify and get -4 over -5
2/5 will be shaded in the original how I got it s that you make a rectangle and make fifths inside and shade in 3/5 of that and see what matches up on the top.
