Answer: $10.20
Step-by-step explanation:
Let's first collect the information from the word problem.
<h3><em>We are told:</em></h3>
- Bought 15 pies and 7 cake slices
- Total cost was $55.22.
- Pies cost
as much as a slice of cake
<h3><em>We need to solve for:</em></h3>
- Total cost of 1 pie and 2 cake slices
1. Create an equation/expression:
To solve the problem, we need to find the price of a pie and cake slice.
Using the information gathered, the equation is:

<em>x = the cost of the slice of cake.</em>
<em />
2. Simplify/Solve

- Great! we have the price of a slice of cake. ($4.25)
Remember that the pie is
of a slice of cake, so now find the price of the pies.
Pie = 
Pie = $1.70
- Awesome! We know a slice of cake costs $4.25 and a slice of pie costs $1.70.
3. Check your work!
<em>Check to make sure the math is done correctly!</em>

Good! It is verified that our calculations are correct.
4. Solve!
1 pie and 2 cakes cost: 
- $10.20 is our final answer!

Hi there!
x=8
<u><em>1.Subtract the answer with the 3 / subtract the terms:</em></u>
<u><em /></u>
<u><em /></u>
<u><em>2.Divide the two terms:</em></u>
<u><em /></u>
<u><em /></u>
Therefore, x=8
<u><em /></u>
cubic means 3 so there is a total o 3 roots
there is 1 real zero ( where the line crosses the x axis) the other 2 would be complex zeros
Answer is D
Answer:
B
Step-by-step explanation:
The volume (V) is calculated as
V = area of triangular face × depth
Area of triangle =
bh ( b is the base and h the height )
Here b = 3 and h = 4 , then
A =
× 3 × 4 = 6 Km²
Now depth = 2, thus
V = 6 × 2 = 12 Km³ → B
