Answer 6

\dfrac{11}{12}-\dfrac{1}6q+\dfrac{5}6q-\dfrac{1}3

Combine like terms to create an equivalent expression.
Enter any coefficients as simplified proper or improper fractions or integers.

Answer 7

[AI-generated answer — Bot GPT 3.5]

To combine like terms in the expression \(\dfrac{11}{12} - \dfrac{1}{6}q + \dfrac{5}{6}q - \dfrac{1}{3}\), we first add the terms involving \(q\) and simplify the constants:

\(\dfrac{11}{12} + \dfrac{5}{6}q - \dfrac{1}{6}q - \dfrac{1}{3}\)

Combining the terms with \(q\): \(\dfrac{11}{12} + \dfrac{5}{6}q - \dfrac{1}{6}q - \dfrac{1}{3}\) simplifies to \(\dfrac{11}{12} + \dfrac{4}{6}q - \dfrac{1}{3}\)

Now, let's simplify the fraction and coefficient of q further:

\(\dfrac{11}{12} + \dfrac{2}{3}q - \dfrac{1}{3}\)

Combining the constants, we get \(\dfrac{11}{12} + \dfrac{2}{3}q - \dfrac{1}{3} = \dfrac{11}{12} + \dfrac{2}{3}q - \dfrac{4}{12}\)

Finally, this simplifies to: \(\dfrac{11}{12} + \dfrac{2}{3}q - \dfrac{4}{12}\)

So, the equivalent expression is: \(\dfrac{11}{12} + \dfrac{2}{3}q - \dfrac{4}{12}\)

Answer 8

3.4-2.8d+2.8d-1.3

Answer 9

[AI-generated answer — Bot GPT 3.5]

In the expression \(3.4 - 2.8d + 2.8d - 1.3\), we can combine like terms by adding the terms with \(d\) and simplifying the constants:

\(3.4 - 2.8d + 2.8d - 1.3\)

Combining the terms with \(d\), the expression simplifies to:

\(3.4 - 1.3\)

Now, subtract 1.3 from 3.4:

\(3.4 - 1.3 = 2.1\)

Therefore, the simplified equivalent expression is \(2.1\).

Answer 10

6\left(\dfrac{1}{2}w-\dfrac{3}{4}\right)

Answer 11

[AI-generated answer — Bot GPT 3.5]

To simplify the expression \(6\left(\frac{1}{2}w - \frac{3}{4}\right)\), we first distribute the 6:

\(6 \times \frac{1}{2}w - 6 \times \frac{3}{4}\)

This simplifies to:

\(3w - \frac{18}{4} = 3w - \frac{9}{2}\)

Therefore, the simplified equivalent expression is \(3w - \frac{9}{2}\)
