Answer:
Cost to paint 4 walls of a room = $24.20
Cost of painting 3 walls of a room =$18.15
Step-by-step explanation:
(a) Abby purchased 4 2/5 gallons of paint to paint 4 walls of a room in her house.
1 gallon cost = 5.50
So 22/5 gallons cost = 
Cost to paint 4 walls of a room = $24.20
(b)cost of painting 4 walls of a room = $24.20
cost of painting 1 wall of a room = 
Cost of painting 3 walls of a room = 6.05 * 3= $18.15
Let the numbers be x and y.
x*y=HCF*LCM=6*60=360
thus
y=360/x
next we find the list of combinations of x and y and test if they satisfy the conditions above:
(6,60),(12,30),(18,20),(24,15)
out of the above, only (6,60) and (12,30) satisfy both conditions. Thus our answer is:
(6,60) or (12,30)
Answer:
$12 per hour
Step-by-step explanation:
In order to find her hourly rate we have to find the amount of dollars billed per hour. To do this we can use this expression: 
Let's use the points (1, 27) and (2, 39) in the expression:
Now let's simplify the expression:
39 - 27 = 12
2 - 1 = 1
The expression simplifies to 12/1, or 12. This means that Brenda is billed $12 every hour she uses her phone.
I hope this helps :)

Let the vertex angle be x.
Base angles in the isosceles triangle are congruent.
Let the base angles be α=34°
Total sum of the inner angles in the triangle is 180°.
We can make equation
2α+x=180° => x=180-2α=180-68=112
The measure of the vertex angle is 112°
Good luck!!!
