Answer:
a = 9
Step-by-step explanation:
2(a + 7) = 5a - 13
We want to bring a to one side, I will choose to bring it to the right
First, expand the bracket by multiplying 2 with a + 7
2a + 14 = 5a - 13
Bring the -13 to the left by adding 13 to both sides
2a + 14 + 13 = 5a - 13 + 13
Simplify
2a + 27 = 5a
Bring the 2a to the right by subtracting 2a from both sides
2a - 2a + 27 = 5a - 2a
Simplify
27 = 5a - 2a
27 = 3a
Bring the 3 to the left by dividing both sides by 3
27÷3 = a
Simplify
a = 9
Answer:
In 29 1/2 days, the total pipe laid is 
mile.
Step-by-step explanation:
The length of pipe laid in 1 day = 1/8 mile
So, the length of pipe laid in half day = half of (1/8 mile)
= 
Now, 29 1/2 days on simplification means 29 and half day.
So, length of pipe in 29 days = 
mile
Now adding the length laid in half day = 
So, in 29 1/2 days, the total pipe laid is mile.
Answer:
{-1,0,1}
Step-by-step explanation:
The domain of a function is the set of all input values. The input values are the first coordinate in any coordinate pair (x,y).
So the domain here is {-1, 0, 1}.
