Answer:

29 degrees

Step-by-step explanation:

angle ABD = (x + 9) degrees

angle DBC = (2x - 19) degrees

angle ABC = angle ABD + angle DBC

50 = (x + 9) + (2x - 19)

= 3x - 10

3x = 50 + 10

x = 60/3

x = 20

Substitute x = 20 into angle ABD = (x + 9)

angle ABD = 20 + 9

angle ABD = 29 degrees

Please help me with this word problem!
IRISSAK [1]

Answer:

f(g)=25g

Step-by-step explanation:

Let g be the number of gallons so f(g) is the number of miles traveled per g gallons.

We know for our problem that Brian's car gets 25 miles per gallon. Since the gallons is represented by g, his car will travel a total distance of 25g (where g is the number of gallons.

We also know that the total distance is given by f(g), so we can put the two expressions together to get our function:

f(g)=25g

Let's check:

- If he uses 1 gallon (g=1), so

f(1)=25(1)

f(1)=25 miles

He will travel 25 miles with one gallon.

- If he uses 2 gallons (g=2), so

f(2)=25(2)

f(2)=50

He will travel 50 miles with two gallon.
