calculate the value of the expression
the quantity 12+(-2) divided by 7 +(-3)+ (2)(-9)
To calculate the value of the expression, we follow the order of operations.
First, we calculate what is inside the parentheses: 12 + (-2) = 10
Next, we calculate any multiplication or division from left to right: (2)(-9) = -18
Now, we have the expression: 10 / 7 + (-3) + (-18)
Now we add and subtract from left to right: 10 / 7 = 1.43
1.43 + (-3) = -1.57
-1.57 + (-18) = -19.57
Therefore, the value of the expression is -19.57.
