8x+3
Combine like terms! Multiply the 3 by the 2x and 1 as well, since it is in parenthesis.
Step-by-step explanation:
The problem asks to find the values "b" and "c" in a way that
the solutions of the equation |x - b| = c are x= 1/2 and x= -1/3.
It means that "b" is the center of the segment [-
].
This segment has the length 
Hence, the half of this length is 
.
Therefore, the center of the segment is 
Thus the value of "b" is found: it is b = 
.
Then the value of "c" is c =
.

Answer:
5.67
Step-by-step explanation:
Let's examine both factors...
1.35 comes from 135, it's 100 times smaller, so this factor would force me to move the decimal point by 2 positions to the left.
4.2 comes from 42, it's 10 times smaller, so this factor would force me to move the decimal point by 1 position to the left.
In total, the decimal point would have to be moved by 3 positions, to the left... so 5,670 would become 5.67
Which is easily verifiable just by looking at the end equation, even without calculating it:
1.35 * 4.2 would give something around 5... not around 50 nor 500.
