Answer:
That is 1 as 1+1=2 and twicing it is 4.
Using front end estimation, we round to the nearest ten, so 13 rounded to the nearest ten is 10, 26 to the nearest ten is 30, and 22 to the nearest ten is 20. We add 10 + 30 + 20 to get 60.

Answer:
x=0.27
Step-by-step explanation:
The given expression is

To solve this equation, we graph the functions:

and

From the graph, the two curves intersects at x=-0.24 and x=0.27.
But the domain of the logarithmic function is x>0
Therefore x=0.27
Answer:
x=14
PN=MN=85
Step-by-step explanation:
It is an isosceles triangle because PQ=MQ and QN is perpendicular to PM. PN=MN
8x-27=6x+1
2x=28
x=14
PN=MN=85
