1. (i) Evaluate without using mathematical tables or calculator:

[tex]\[ \frac{-2(5+3) - 9 \div 3 + 5}{-3 \times -5 + 2 \times 4} \][/tex]


Sagot :

Let's solve the given expression step-by-step.

Given expression:
[tex]\[ \frac{-2(5+3) - 9 \div 3 + 5}{-3 \times -5 + 2 \times 4} \][/tex]

### Step 1: Evaluate the numerator

First, we simplify the numerator:
[tex]\[ -2(5+3) - 9 \div 3 + 5 \][/tex]

#### Step 1.1: Resolve the parentheses
[tex]\[ -2(8) - 9 \div 3 + 5 \][/tex]

#### Step 1.2: Perform the multiplication and division
[tex]\[ -16 - 3 + 5 \][/tex]

#### Step 1.3: Combine the terms
[tex]\[ -16 + 5 - 3 = -14 \][/tex]

So, the numerator is [tex]\(-14\)[/tex].

### Step 2: Evaluate the denominator

Now, we simplify the denominator:
[tex]\[ -3 \times -5 + 2 \times 4 \][/tex]

#### Step 2.1: Perform the multiplications
[tex]\[ 15 + 8 \][/tex]

#### Step 2.2: Add the results
[tex]\[ 23 \][/tex]

So, the denominator is [tex]\(23\)[/tex].

### Step 3: Perform the division

Finally, we divide the numerator by the denominator:
[tex]\[ \frac{-14}{23} \][/tex]

This simplifies to approximately [tex]\(-0.6087\)[/tex].

### Final Answer

The evaluated result of the given expression is:
[tex]\[ \frac{-2(5+3)-9 \div 3+5}{-3 \times -5+2 \times 4} = -0.6087 \][/tex]
