Study Notes

Simplifying Expressions

The expression (3 + 8x + 11) simplifies to (8x + 14).
The expression (3(72x)) calculates to (216x).

Evaluating Expressions

Evaluating ((-3 + 5) + (-2)) results in (0).
The sum (-2 + (-3) + (-7)) equals (-12).
The computation (-14 + 2 + (-9) + 25) simplifies to (4).
The evaluation of (83 + (-34) + (-62)) gives (-13).
The expression (27 - 217) results in (-190).
Evaluating (17 - (-13)) yields (30).
The calculation (112 - (53 - 8)) results in (67).
The expression ((26 - 35) - (-13)) simplifies to (4).
The evaluation of ((104 - 96) - (-8)) gives (16).
The expression (75 - (-15) + (-30) - 20) simplifies to (40).

Combining Like Terms

The expression (7a + (-8) + 5) simplifies to (7a - 3).
The expression (-4 + (-2x) + 6) combines to (2 - 2x).
The computation (6a + 5a) results in (11a).
The expression (18t - (-6)t) simplifies to (24t).
Evaluating (3(x + 2) + 8(x - 3) - 6x) gives (5x - 18).

Solving Equations

For consecutive integers summing to (53):
- Let (x) be the first integer. The second integer is (x + 1).
- Set the equation (x + (x + 1) = 53). Solving gives the integers (26) and (27).
For three consecutive integers summing to (81):
- Set (81 = 3x + 3). Solving the equation gives consecutive integers (26), (27), and (28).

Evaluating Fractions

The calculation (\frac{1}{4}(-36)) results in (-9).
Evaluating (-\frac{1}{7}(-35)) yields (5).
The expression ((-63a) \div (-9)) simplifies to (7a).
The computation ((85c) \div (-5)) gives (-17c).
The expression (\frac{143a}{-13}) simplifies to (-11a).
Evaluating (-\frac{355x}{5x}) results in (-71x^2) for (x \neq 0).

Calculating Averages

The average of the numbers (22), (-8), (-23), and (-7) is (-4).
For the numbers (21), (-13), (-18), and (34), the average is (6).
