Answer:
66 degree
Step-by-step explanation:
given:
angle FAB = 48 degree
angle ECB = 18 degree
in triangle HBC , angle H is also 48 degree degree since the line is parallel the connection between angle H and angle A is alternate interior angle and alternate interior angle are always equal.
so angle H = 48 degree
in triangle HBC
angle H + angle C = angle ABC (sum of two interior opposite angles are equal to the exterior angle formed)
48 + 18 = angle ABC
66 = angle ABC
Answer: -x + 4y
Step-by-step explanation:
-3(2x-y) + 2y+2(x+y)
-6x + 3y + 2y + 2x + 2y
-6x + 2x +3y + 2y + 2y
-6x + 5x + 4y
-x + 4y
Answer. True

Answer: it will take Doug's son 6 days if he works alone
Step-by-step explanation:
It takes dad three days to re-roof a house. If his son helps him the job can be done in two days. This means that the time that the job takes will reduce because they worked together.
Let x = the number of days it will take Doug's son if he works alone,
Doug's unit rate of working will be 1/3
Doug son's unit rate of working will be 1/x
Their unit rates are additive because they will work simultaneously. Each will work at his own unit rate.
Combined unit rates will be
1/3 + 1/x = (x + 3)/3x
Since it will take 2 days if they work together, their combined unit rate will be 1/2
(x + 3)/3x = 1/2
2(x + 3) = 3x
2x + 6 = 3x
3x - 2x = 6
x = 6 days
Here is an example 8(3x+2) first you would multiply 8 times 3x and you would get 24x, and then you would multiply 8 times 2 and you get 16 so your final answer is 24x+16
