Answer:
Yesss
Step-by-step explanation:
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
Answer:
7 cents/mile
Step-by-step explanation:
You are looking for a unit rate of cents per mile.
Change the dollar amount to cents, and divide by the number of miles.
$13.08 * (100 cents)/$ = 1308 cents
(1308 cents)/(183 miles) = 7.001 cents/mile
Answer:
-7 = h
Step-by-step explanation:
15.3 + 1h = 1.3 - 1h
<u> +1h +1h</u>
15.3 + 2h = 1.3
Remember what you do to one side you MUST do to the other.
15.3 + 2h = 1.3
<u>-15.3 -15.3</u>
2h = -14
Now to isolate the variable you divide both sides by 2 to get, h = -7
Hope that helps and have a great day!
