Answer:
7/2 or 3.5
Step-by-step explanation:
The y-axis represents the cost is dollars. The x-axis is the amount of gasoline in gallons. To find the cost in dollars per gallon, choose a point on the graph, and divide the dollars (y-coordinate) by the gallons (x-coordinate).
cost = (21/4) / (3/2)
cost = 21/4 * 2/3
cost = 42/12
cost = 7/2 = 3.5
Answer:
See below
Step-by-step explanation:
Start by subtracting 5.2 from both sides of the equation
so "subtraction property of equality " I suppose ......
then the next step would be divide both sides by 2.5
which would be division property of equality
Answer:
x=5
Step-by-step explanation:
We can use the Triangle Angel Bisector Theorem
AB 2x-1
----------= --------------
AC 3x
9 2x-1
----------= --------------
15 3x
Using cross products
3x*9 = 15*(2x-1)
Distribute
27x = 30x-15
Subtract 30x from each side
27x-30x = 30x-30x-15
-3x = -15
Divide by -3
-3x/-3 =-15/-3
x =5
3 + 2 = 1 + 4
2 + 15 = 10 + 7
8 + 9 = 19 - 2
12 - 7 = 14 - 9
Hope this helped!
