Explanation

Waheed runs 9 miles in 1 hour.

We need to find how many hours it will take him to run 108 miles.

= 108 ÷ 9 = 12 hours

Explanation

We are given the equation:

w = (2/3)t + 6

and asked to find w when t = 12.

Step-by-step:

w = (2/3 × 12) + 6

w = 8 + 6

w = 14

Explanation

42 ÷ 7 = Rs. 6 per folder

50 ÷ 6 ≈ Rs. 8.33 per folder

56 ÷ 8 = Rs. 7 per folder

72 ÷ 9 = Rs. 8 per folder

Explanation

Sum of angles in a quadrilateral = 360°

Given angles:

• 109°
• 67°
• 82°

Add them:

109 + 67 + 82 = 258°

Now subtract from 360°:

360° − 258° = 102°

Explanation

The first set {-7.2322, ..., √5, √15, 8.27541 ...} includes only irrational numbers because:

• √5 and √15 are irrational (not perfect squares).
• The decimals appear non-repeating and non-terminating.

Explanation

The model shown (– – – → + +) suggests starting with a negative and ending with a positive result.

–2 + 3 = 1, which matches that transition from negative to positive.

Explanation

On the number line, Point X is clearly positioned at -4, which is four units left of 0.

Explanation

The diamond symbol is placed at -3 on the number line, it directly matches the position mentioned.

Since symbols on a number line represent specific values, the diamond at -3.

Explanation

The equation 3(4x) = (4x)3 shows that the order of multiplication does not affect the result.

This is the Commutative Property of Multiplication, where a × b = b × a.

Explanation
