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.
Hope ot helps!
With this equation, all you have to do to solve for a is to divide both sides by 12b and <u>your answer will be 
</u>
Answer: 36.75
Step-by-step explanation:
147 degree = 4x

Answer:m
M=11/2
Step-by-step explanation:
Slope is equal to the change in y over the change in x, or rise over run.m=change in y change in x The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).m=y2−y1x2−x1 Substitute in the values of x
and y into the equation to find the slope.m=−4−(7)−6−(−4)
