Answer:
Use all the given information:
<em>Price of a slice in $ -</em><em> x</em>
<em>Number of slices- </em><em>3</em>
<em>Total cost of slices-</em><em> 3x</em>
<em />
<em>Price of chopped cheese in $- </em><em> 2+x</em>
<em>Number of chopped cheeses-</em><em> 4</em>
<em>Total cost of chopped cheeses-</em><em> 8+4x</em>
<em />
<em>Total cost- </em><em>7x+8</em>
<em />
Step-by-step explanation:
We are told that the price of a slice is x and that Dashaun bought 3 slices.
So to find the total amount paid for slices, multiply the price by the number of slices:
We are told that the price of chopped cheese is $2 more than a slice. Use y as the cost for chopped cheese:
Dashaun bought 4 chopped cheeses.
To find the total cost of chopped cheeses bought, multiply the cost per cheese by the amount of cheese purchased:
Insert the value of y:
Use the distributive property:
This is the total cost for the chopped cheeses.
To find the total of lunch, add the prices for the slices and cheeses together:
The total cost for lunch is <em>7x+8</em>

The radius of the hemisphere is 9.5 inches.
The diameter of the hemisphere is 19 inches.
The surface area of the hemisphere is 850.2 inches²
<h3>How to find the surface area of an hemisphere?</h3>circumference of a circle = 2πr
where
- r = radius
Therefore,
19π = 2πr
2r = 19
r = 19 / 2
r = 9.5 inches
diameter = 9.5 × 2 = 19 inches
Therefore,
surface area of an hemisphere = 3πr²
surface area of an hemisphere = 3 × 3.14 × 9.5²
surface area of an hemisphere = 850.155 inches²
surface area of an hemisphere = 850.2 inches²
