To expand and distribute -5(-3-11g), we can use the distributive property. The general form of the distributive property is a(b + c) = ab + ac.
In this case, a is -5, b is -3, and c is -11g. So, the expression becomes:
-5 * -3 + -5 * -11g
Simplifying further, we get:
15 + 55g
Therefore, the expanded and distributed form of -5(-3-11g) is 15 + 55g.
here are the answer options:
-55g + 15
-55g + 15
55g - 15
55g - 15
55g + 15
55g + 15
-55g - 15
Apologies for the error in my previous response. The correct expanded and distributed form of -5(-3-11g) is -55g + 15. Therefore, the correct answer option is: -55g + 15.

To simplify the expression 2/8x + 3/10y - 5/8x + 4/10y, we need to combine like terms.
Like terms are terms that have the same variables raised to the same powers. In this case, we have "x" terms and "y" terms.
First, let's combine the "x" terms:
2/8x - 5/8x = (2 - 5)/8x = -3/8x
Now, let's combine the "y" terms:
3/10y + 4/10y = (3 + 4)/10y = 7/10y
Therefore, the simplified expression is: -3/8x + 7/10y.

To evaluate the expression a - b/3 when a = 9 and b = 6, we substitute the values of a and b into the expression.
a - b/3 = 9 - 6/3
First, we simplify the fraction 6/3:
6/3 = 2
Now, we substitute this value back into the expression:
9 - 2 = 7
Therefore, when a = 9 and b = 6, the value of a - b/3 is 7.
