Answer:
The correct answer is a) 16
Step-by-step explanation:
To find this first distribute the interior negative to both terms in the parenthesis.
9 - {x - (7 + x)}
9 - {x - 7 - x}
Now simplify the like terms.
9 - {-7}
Now distribute the negative once again.
9 + 7
And complete the indicated operation.
16
5x - 6 = 29
Add 6 to both sides
5x = 25
Divide both sides by 5
x = 5
After you have multiplied but you have all these numbers, look to see how many decimal places the numbers you have multiplied.
Lets say you multiply:
23.45
x 2.1
= 49.245
Because your first number had 2 decimal places and your second number had 1 decimal place you add that and that is how many decimal places your product has. In this case there is three.
