1. The given expression is $12t + 20$. 2. This is a linear algebraic expression in terms of $t$.

1. **State the problem:** Solve the equation $$\frac{4}{3b-3} = \frac{9}{b+3}$$ for $b$. 2. **Rewrite the equation:** We have two fractions set equal: $$\frac{4}{3b-3} = \frac{9}{b

1. The problem is to find the domain and range for the function $y=4^x$. 2. The domain of an exponential function $y=a^x$ where $a>0$ and $a \neq 1$ is all real numbers because $x$

1. Stating the problem: Simplify the expression $$\frac{1}{x^2-3} + \frac{1}{x^2+2}$$. 2. Find a common denominator which is the product of the two denominators: $$ (x^2-3)(x^2+2)

1. Problem 48: Given $$S=\frac{2x+t}{r}$$, solve for $$x$$. Multiply both sides by $$r$$ to clear the denominator:

1. We are asked to factorise the quadratic expression $81c^2 - 16d^2$. 2. Notice that this is a difference of squares because $81c^2 = (9c)^2$ and $16d^2 = (4d)^2$.

1. **State the problem:** Simplify the expression $$(9a + 4b) - (-9b + 8a)$$. 2. **Remove parentheses:** Subtracting the second parentheses means distributing a minus sign:

1. We are asked to multiply the complex numbers $(3+2i)$ and $(4+5i)$. 2. Use the distributive property (FOIL method):

1. The problem asks for algebraic assistance or tutoring based on your request. 2. Since no specific problem was given, please provide an algebra question or math topic you need he

1. The inequality $x \geq y$ means that $x$ can be either greater than or equal to $y$. 2. This includes both possibilities: $x > y$ (greater than) and $x = y$ (equal to).

1. The problem is to solve an equation or expression directly with a complete solution. 2. Since no specific equation was provided, please provide the exact equation or expression

1. The problem involves understanding the expression given the inequality $x > y$ and interpreting $x - z$. 2. We are to identify which option correctly matches the expression or a

1. The problem presents the expression $$\frac{0 - 11}{17.54} = 114 \quad \text{and} \quad \frac{55.56 + 114}{n} = 10a$$ and seems to ask to analyze or solve these. 2. First, simpl

1. The problem seems to be about understanding the expression $x - z$ given the inequality $x > y$. 2. The expressions in options a, b, c, and d involve $y$, $z$, and variations wi

1. We are given the condition $x \geq y$ and want to analyze which of the options correctly completes the statement $x - z \geq$ something. 2. Since $x \geq y$, subtracting $z$ fro

1. We are given the variable \( \text{old mode} = 2.1 \).\n\n2. Since this is a statement of a value and not an equation or problem to solve, the value of \( \text{old mode} \) is

1. State the problem: Solve the inequality $-5x \geq 9$ and find the solution set from the replacement set $\{-4, -3, -2, -1, 0, 1\}$.\n\n2. Solve the inequality algebraically: \n$

1. Let's identify what the symbol \( \neq \) means in mathematics. 2. The symbol \( \neq \) stands for "not equal to." This means two values are different.

1. State the problem: Solve the equation $2x - 4 = 16$ for $x$. 2. Add 4 to both sides to isolate the term with $x$:

1. **Problem:** Create a simple algebra worksheet for students involving solving linear equations. 2. Solve for $x$: $$2x + 5 = 13$$

1. **State the problem:** Solve the equation $20 - x = 10$ for $x$. 2. **Isolate the variable:** To find $x$, subtract 20 from both sides:
