<u>Step 1: Define</u>
<em>Identify</em>
Point (7, 0)
Equation y = x - 7
<u>Step 2: Find</u>
- Substitute in point [Equation]: 0 = 7 - 7
- Subtract: 0 = 0
Since 0 = 0 is true, then it would be a solution to the equation.
Answer:
The number of calories is going to be pretty close to proportional to the area of the pizza. Figure out the area of a 6-ince pizza, and then figure out the area of a 14-inch pizza. Then you're going to get a proportion:
(Area of 14 inch pizza) is to (Area of 6 inch pizza) as (Number of calories in 14 inch pizza) is to (Number of calories in 6 inch pizza.
You know the areas of both sizes and the number of calories in the 6 inch pizza, so you should be able to find the number of calories in the 14 inch pizza.
Then divide by 8 to get the number of calories in each slice.
Answer: 3 balloons
Step-by-step explanation:
The ratio would be pink balloons to total balloons (aka pink/total), so 5 to 20 (aka 5/20). This simplifies to 1/4. If the new total is 12, and x represents pin balloons, then you can do 1/4=x/12. By cross multiplying, you get 12=4x. Divide both sides by 4 and x would equal 3. Therefore, the party store should expect to sell 3 pink balloons.
