Solve Linear Equation
1. Stating the problem: Solve the equation $x + \frac{5}{4} = -\frac{1}{2}$ for $x$.
2. To isolate $x$, subtract $\frac{5}{4}$ from both sides:
Fraction Addition
1. **State the problem:** Calculate $-\frac{8}{15} + 0.6$.
2. **Convert 0.6 to a fraction:**
Simplify Fraction
1. Stating the problem: Simplify the expression $$\frac{-8}{15} + 0$$.
2. Since adding zero to any number does not change its value, the expression remains $$\frac{-8}{15}$$.
Solve Equation
1. Stating the problem: Solve the equation $x - \frac{3}{4} = \frac{2}{7}$ for $x$.
2. To isolate $x$, add $\frac{3}{4}$ to both sides of the equation:
Multiply Negative Fractions
1. Stating the problem: Calculate the product of $2.8$ and $-\frac{20}{7}$.
2. Express the multiplication explicitly:
Function Machine

2. Input to function mach
Factorization And Calculus
1. **Express the following in factors:**
(i) Simplify $\frac{(n+2)!}{(n+2)!} = 1$ because any nonzero number divided by itself equals 1.
Missing Problem
1. The problem asks to solve two subproblems: 1a and 1b.
2. Since the specific problems 1a and 1b are not visible from the provided Google Drive link, I cannot directly access them
Solve Linear Equation
1. **State the problem:** Solve the equation $8f=96$ for $f$.
2. **Isolate $f$:** To solve for $f$, divide both sides of the equation by 8.
Base Equation
1. The problem gives the equation $17_r = 5$ and asks to find $r$.
2. The notation $17_r$ means the number 17 in base $r$.
Solve For F
1. The problem states that 3 times a number $f$ equals 15, or mathematically, $3f=15$.
2. To find the value of $f$, divide both sides of the equation by 3 to isolate $f$:
