To solve this problem, we can set two equations.
Let x be the cost of coffee and y be the cost of latte.
Two coffees and one latte: 2x + y = 10.50
y=10.50 - 2x ...(1)
Three coffees and two lattes: 3x + 2y = 17.00...(2)
Put (1) into (2), we have:
3x + 2(10.50-2x) = 17.00
3x + 2(10.50) - 2(2x) = 17.00
3x + 21 - 4x = 17
Put the unknown to one side:
3x -4x = 17 - 21
-x = -4
When there are negative numbers on both sides, we can take the negative signs away:
x= 4
Therefore, cost of one coffee is A. $4.00.

Answer:
OR
Step-by-step explanation:
Vertex form of a parabola is given as:
Where (
) is the vertex and 
are the points on the parabola.
We are given that, the vertex is (3, -2) and another point on parabola is given as (2, 3).
First of all, putting the vertex in the vertex equation as given above:
Now, putting the values of 
as 2, 3 and let us find the unknown variable 
:
Therefore, the equation in vertex form can be written as:
OR
A- 5.3 cm
B- 17.8m
C-9.7 in
D-12 cm
E- 8.3ft
F-25.5m
Answer: x=26-14
Step-by-step explanation :you need to subtract on both sides so that why it is x=26-14.
